* The name of this '''toolbox''' is '''test underscore toolbox.'''

* The purpose of this '''toolbox''' is to demonstrate how to add an external '''C library'''.

* It contains commands required to compile the external library '''mul.c '''file in to a '''dot so''' file

* It also automatically copies the '''dot so '''file and '''header file''' into a '''directory''' named as '''thirdparty'''

This '''thirdparty '''directory is now ready to be used in the '''test_toolbox'''

Before that, here are some important points about the library compilation process

depends on the '''Operating System''' in use.

* It also depends on the targeted external '''software library'''.

* Most '''libraries''' will provide specific '''build''' instructions such as '''make, cmake '''etc.

* These could be crucial in order to generate '''libraries''' in the correct form.

* The '''toolbox''' makes use of a '''Gateway Function''' to communicate with the '''library'''.

* Every new '''function''' added via an external '''library,''' requires a separate '''gateway function'''.

* These '''gateway functions''' are '''CPP files''' inside the '''sci gateway slash cpp directory'''.

|-
|On slide
| Dear Friends,

Welcome to the spoken tutorial on '''“LaTeX on Windows using TeXworks”'''

|-
|On slide

| In this tutorial we will learn to,
# Download and install '''MikTeX'''
# Write basic '''LaTeX''' documents using '''TeXworks'''
# Configure '''MikTeX''' to download missing packages

|-
|On slide
| To record this tutorial, I am using '''Windows7 '''operating system and MikTeX2.9

|-
|On slide

| Let us now see the salient features of '''TeXworks'''

# It is platform independent
# It has an embedded pdf reader
# It supports Indian language typesetting

|-
|On slide

| Before we start with '''TeXworks''', we have to install '''MikTeX'''.

'''MikTeX''' is an up-to-date implementation of '''TeX/LaTeX''' and related programs for '''Windows'''.

It contains the necessary packages to create basic documents in '''LaTeX '''on '''Windows'''

Moreover, '''TeXworks''' is a default editor available with '''MikTeX''' installation.

|-
| On the browser
|Go to the website [http://www.miktex.org/ www.]'''miktex'''[http://www.miktex.org/ .org]

|-
|Click on that link

| Click on the download link for recommended '''MikTeX''' installer.

This will download the '''MikTeX''' installer.

|-
| Choose Desktop in Save location

|Download and save it on your '''Desktop.'''

It is a large file, about 154 mega bytes.

Hence, it will take some time to download.

|-
| Switch to the Desktop and point to the file.
|I have already downloaded this file. Here it is.

|-
|Double-click >> click Run

| Double click on this file to start the installation.

Check the check box and click on '''Next'''.

Choose all default options.

|-
| Show the installation process

|The installation will take around 5 to 10 minutes.

I have already installed '''MikTeX''' on my computer.

Hence I will not proceed with the installation.

|-
|
|After successfully installing '''MikTeX''' on your computer,

let us see how to use the '''TeXworks''' editor which comes with '''MikTeX.'''

|-
|Click on Windows>>All programs >> '''MikTeX'''>>'''TeXworks'''

| Click on the '''Windows start''' button.

Click on '''All Programs'''.

Click on '''MikTeX2.9'''

Click on '''TeXworks'''

|-
|
| '''TeXworks''' editor will open.

Let me open an already existing '''LaTeX''' document.

|-
| Click on File >> Open >> hello.tex
|I will click on '''File,''' then click on '''Open''' and choose the directory.

Then I will open the file '''hello.tex'''.

|-
|Point to some of the coloured text

Point also to the user content

| You can see that the text written in the file is colored.

This is called '''syntax''' '''highlighting'''.

It helps the user differentiate between the user content and the '''LaTeX''' syntax.

|-
|
|In case the '''LaTeX''' syntax is not highlighted, do the following.

|-
|Click on Format
| In the '''TeXworks''' window, click on '''Format''' button available on the '''Menu bar'''.

|-
|Select '''Syntax Colouring'''>>'''LaTeX'''.
| Select '''Syntax Colouring''' and then click on '''LaTeX'''.

|-
|
| If you want '''TeXworks''' to apply '''syntax highlighting''' every time you create a '''LaTeX''' document, do the following

|-
| Click on '''Edit''' >> '''Preferences'''
|On the '''menu''' bar, click on '''Edit''' and then click on '''Preferences'''.

|-
| Editor tab>> dropdown>> Syntax Colouring
|In the '''Editor''' tab, click on the dropdown button which gives options for '''Syntax Colouring'''.

|-
| Choose '''LaTeX'''>>Ok
|Choose '''LaTeX''' and then click on '''Ok.'''

|-
|
|In this way, '''syntax''' '''highlighting''' will be applied to all documents created in the future.

|-
|
|Now we are ready to compile our '''LaTeX''' document.

|-
|Press Ctrl+T keys
| Press '''Ctrl''' and '''t''' keys together to start the compilation.

|-
|
| Once the document is compiled without errors, the resulting '''pdf''' will be opened.

|-
| Point to the pdf document
|Note that this '''pdf''' reader comes along with '''TeXworks.'''

It is the default '''pdf''' reader used by '''TeXworks''' to display the compiled '''pdf''' documents.

|-
| On slide
|We have completed the basic installation of LATEX

This is sufficient for many formatting requirements

You may now leave this tutorial

Practice the remaining LATEX tutorials on the playlist

|-
| On slide
|While practising other tutorials, you may get the following error message:
“The required file ABC is missing.
It is a part of the following package:
XYZ”

Here ABC is a file inside the package XYZ

ABC and XYZ will be specific to your case

|-
| On slide
|When you get such an error message, listen to the rest of THIS tutorial

Two ways to solve that problem are explained in the rest of this tutorial

At least one of them should work for you

Goodbye for now

|-
| On slide
|Do you want to know how to solve a problem of the following type:
“The required file ABC is missing.
It is a part of the following package:
XYZ”

Listen to the rest of this tutorial and practise with me

|-
|
| Now let us compile a '''Beamer''' document.

|-
| On slide

|Beamer package by default is not included in the '''MikTeX''' setup that we have installed.

This means that we have to
*download it from some source and
*add it to our current '''MikTeX''' distribution

|-
| On slide

|There are two ways of installing a missing package.

One way is to install it on the fly while we are compiling a '''LaTeX''' document

This '''LaTeX''' document will typically require a package not available in your '''MikTeX''' distribution.

Other way, is to manually choose and install a package using '''Package''' '''Manager''' of '''MikTeX'''.

|-
|
|Let us see the first method.

|-
|
| We will
* open and compile a '''LaTeX''' document,
* which requires '''MikTeX'''
* to install packages from the '''internet'''.

|-
| Close '''TeXworks'''
|First close the '''TeXworks''' editor.

|-
|Click on Start>> All programs >> '''MikTeX'''

| It is required that we open the '''tex''' file with administrator privileges.

Click on the '''start''' button.

Then click on '''All programs'''.

Click on '''MikTeX2.9'''

|-
| Right-click '''TeXworks''' >> Run as Administrator
|Right click on '''TeXworks''' and choose '''Run as Administrator'''

This will launch the '''TeXworks''' editor with '''administrator''' privileges.

|-
|Click on File>> Open>> beamer.tex
| Now click on '''File.'''

Then click on '''Open'''

Choose the file '''beamer.tex'''

|-
|Press Ctrl+T keys
| Press '''Ctrl''' and '''t''' keys together to start the compilation.

|-
| Dialog box
|A '''Package Installation '''dialog box will open.

It will ask to install the missing package '''beamer.cls. '''

|-
|Click Change
| Click on '''Change '''button on this dialog box.

|-
| Dialog box
|'''Change Package Repository '''dialog box will open.

|-
|Choose as told
| Choose the option '''Packages shall be installed from the internet option.'''

|-
|Click Connection Settings
| Click on '''Connection Settings.'''

|-
|
| It will prompt you to configure the '''proxy''' settings.

|-
| Point to '''Use proxy server '''option
|If you are not on a '''proxy''' network then leave the '''Use proxy server checkbox''' unchecked.

|-
| Click on the checkbox
|Since i am on a '''proxy''' network, i will enable the option by clicking on the checkbox

|-
|Type proxy address
| I will enter the '''proxy''' address.

|-
|Type the port number
| I will enter '''proxy''' port number.

|-
|Click on '''Authentication required '''checkbox
| I will enable the option '''Authentication required '''by clicking on the corresponding checkbox

|-
|Click OK>>Next
| Click on '''Ok'''. And then click on '''Next'''

|-
|
| It will ask me the '''proxy username '''and''' password.'''

|-
|Enter proxy>>OK
| I will enter the information and click on '''OK'''.

|-
|Choose one repository >> Finish
| It will show a list of various remote package repositories.

Choose one from the list and click on '''Finish.'''

|-
|Click Install
| Click on '''Install'''.

It will install the '''beamer.cls '''package

|-
|Dialog box
| Once again the '''Package Installation '''dialog box will open.

|-
| Point to '''pgfcore.sty'''
|It will prompt to install the missing package '''pgfcore.sty.'''

|-
| Uncheck the checkbox
|You may uncheck the option '''Always show this dialog before installing packages'''.

If you do this, '''MikTeX''' will not prompt you again, if it encounters a missing package.

|-
| Click Install
|Click on '''Install.'''

|-
|
|Now if there any more missing packages, it will automatically install it, without asking for your permission.

|-
| Point to the output side.
|Once the installation completes, it will finish the compilation and open the '''pdf''' output.

We can see that we have successfully compiled a '''Beamer''' document.

|-
|Click on Start >>All programs >>'''MikTeX'''>> Maintenance(Admin) >> Package Manager(Admin)

| Now let us see the second method of installing missing packages.

Click on the '''Windows''' start button.

Click on '''All Programs'''.

Click on '''MikTeX2.9'''

Click on '''Maintenance (Admin)'''

Cick on '''Package Manager (Admin)'''

|-
|
| It will show a list of various packages available

Now let us take a look at this list.

|-
| Point to the columns
|There are six columns in this list.

These are '''Name, Category, Size, Packaged date, Installed on date''' and '''Title'''.

|-
|
|The '''Installed on''' column is very important to us.

|-
| Point to the blank column entries
|The packages for which this column is blank indicates that these packages are not installed.

|-
|
|Let us see how to install a particular package.

|-
|check this step of proxy authentication
| Let me choose the package '''abc''', for example.

|-
| Point to the plus button
|Notice that the moment I choose the package, the '''plus''' button on the top left side gets enabled.

|-
| Click on the plus button
|The '''plus''' button is the '''install''' button.

Click on the '''plus''' button.

|-
|
|A window will open which will list the number of packages you have chosen to install or uninstall.

|-
| Click Proceed
|Click on '''Proceed'''.

|-
| Proxy dialog box
|Since I have configured a '''proxy''' network connection, it will prompt me for the '''proxy username''' and '''password'''.

|-
| Type proxy
|Let me type my '''username''' and '''password'''

|-
| Click Ok
|Click on '''Ok'''

|-
|Window

| A window will open which will show the download progress of the package selected for installation.

It may happen that it fails to download the requested package due to remote server connectivity issues.

In that case, change the package repository and try again.

|-
| Click Close
|We can see that the installation of selected package is completed.

Click on '''Close'''.

|-
| Point to the entry
|The package list will get refreshed.

Notice that 11 september 2013 appears in the '''Installed''' '''on''' column for package '''abc.'''

'''MikTeX''' is an up-to-date implementation of '''TeX/LaTeX''' and related programs for '''Windows'''.

It contains the necessary packages to create basic documents in '''LaTeX '''on '''Windows'''

Moreover, '''TeXworks''' is a default editor available with '''MikTeX''' installation.

|-
| On the browser
|Go to the website [http://www.miktex.org/ www.]'''miktex'''[http://www.miktex.org/ .org]

|-
|Click on that link

| Click on the download link for recommended '''MikTeX''' installer.

This will download the '''MikTeX''' installer.

|-
| Choose Desktop in Save location

|Download and save it on your '''Desktop.'''

It is a large file, about 154 mega bytes.

Hence, it will take some time to download.

|-
| Switch to the Desktop and point to the file.
|I have already downloaded this file. Here it is.

|-
|Double-click >> click Run

| Double click on this file to start the installation.

Check the check box and click on '''Next'''.

Choose all default options.

|-
| Show the installation process

|The installation will take around 5 to 10 minutes.

I have already installed '''MikTeX''' on my computer.

Hence I will not proceed with the installation.

|-
|
|After successfully installing '''MikTeX''' on your computer,

let us see how to use the '''TeXworks''' editor which comes with '''MikTeX.'''

|-
|Click on Windows>>All programs >> '''MikTeX'''>>'''TeXworks'''

| Click on the '''Windows start''' button.

Click on '''All Programs'''.

Click on '''MikTeX2.9'''

Click on '''TeXworks'''

|-
|
| '''TeXworks''' editor will open.

Let me open an already existing '''LaTeX''' document.

|-
| Click on File >> Open >> hello.tex
|I will click on '''File,''' then click on '''Open''' and choose the directory.

Then I will open the file '''hello.tex'''.

|-
|Point to some of the coloured text

Point also to the user content

| You can see that the text written in the file is colored.

This is called '''syntax''' '''highlighting'''.

It helps the user differentiate between the user content and the '''LaTeX''' syntax.

|-
|
|In case the '''LaTeX''' syntax is not highlighted, do the following.

|-
|Click on Format
| In the '''TeXworks''' window, click on '''Format''' button available on the '''Menu bar'''.

|-
|Select '''Syntax Colouring'''>>'''LaTeX'''.
| Select '''Syntax Colouring''' and then click on '''LaTeX'''.

|-
|
| If you want '''TeXworks''' to apply '''syntax highlighting''' every time you create a '''LaTeX''' document, do the following

|-
| Click on '''Edit''' >> '''Preferences'''
|On the '''menu''' bar, click on '''Edit''' and then click on '''Preferences'''.

|-
| Editor tab>> dropdown>> Syntax Colouring
|In the '''Editor''' tab, click on the dropdown button which gives options for '''Syntax Colouring'''.

|-
| Choose '''LaTeX'''>>Ok
|Choose '''LaTeX''' and then click on '''Ok.'''

|-
|
|In this way, '''syntax''' '''highlighting''' will be applied to all documents created in the future.

|-
|
|Now we are ready to compile our '''LaTeX''' document.

|-
|Press Ctrl+T keys
| Press '''Ctrl''' and '''t''' keys together to start the compilation.

|-
|
| Once the document is compiled without errors, the resulting '''pdf''' will be opened.

|-
| Point to the pdf document
|Note that this '''pdf''' reader comes along with '''TeXworks.'''

It is the default '''pdf''' reader used by '''TeXworks''' to display the compiled '''pdf''' documents.

Listen to the rest of this tutorial and practise with me

|-
|
| Now let us compile a '''Beamer''' document.

|-
| On slide

|Beamer package by default is not included in the '''MikTeX''' setup that we have installed.

This means that we have to
*download it from some source and
*add it to our current '''MikTeX''' distribution

|-
| On slide

|There are two ways of installing a missing package.

One way is to install it on the fly while we are compiling a '''LaTeX''' document

This '''LaTeX''' document will typically require a package not available in your '''MikTeX''' distribution.

Other way, is to manually choose and install a package using '''Package''' '''Manager''' of '''MikTeX'''.

|-
|
|Let us see the first method.

|-
|
| We will
* open and compile a '''LaTeX''' document,
* which requires '''MikTeX'''
* to install packages from the '''internet'''.

|-
| Close '''TeXworks'''
|First close the '''TeXworks''' editor.

|-
|Click on Start>> All programs >> '''MikTeX'''

| It is required that we open the '''tex''' file with administrator privileges.

Click on the '''start''' button.

Then click on '''All programs'''.

Click on '''MikTeX2.9'''

|-
| Right-click '''TeXworks''' >> Run as Administrator
|Right click on '''TeXworks''' and choose '''Run as Administrator'''

This will launch the '''TeXworks''' editor with '''administrator''' privileges.

|-
|Click on File>> Open>> beamer.tex
| Now click on '''File.'''

Then click on '''Open'''

Choose the file '''beamer.tex'''

|-
|Press Ctrl+T keys
| Press '''Ctrl''' and '''t''' keys together to start the compilation.

|-
| Dialog box
|A '''Package Installation '''dialog box will open.

It will ask to install the missing package '''beamer.cls. '''

|-
|Click Change
| Click on '''Change '''button on this dialog box.

|-
| Dialog box
|'''Change Package Repository '''dialog box will open.

|-
|Choose as told
| Choose the option '''Packages shall be installed from the internet option.'''

|-
|Click Connection Settings
| Click on '''Connection Settings.'''

|-
|
| It will prompt you to configure the '''proxy''' settings.

|-
| Point to '''Use proxy server '''option
|If you are not on a '''proxy''' network then leave the '''Use proxy server checkbox''' unchecked.

|-
| Click on the checkbox
|Since i am on a '''proxy''' network, i will enable the option by clicking on the checkbox

|-
|Type proxy address
| I will enter the '''proxy''' address.

|-
|Type the port number
| I will enter '''proxy''' port number.

|-
|Click on '''Authentication required '''checkbox
| I will enable the option '''Authentication required '''by clicking on the corresponding checkbox

|-
|Click OK>>Next
| Click on '''Ok'''. And then click on '''Next'''

|-
|
| It will ask me the '''proxy username '''and''' password.'''

|-
|Enter proxy>>OK
| I will enter the information and click on '''OK'''.

|-
|Choose one repository >> Finish
| It will show a list of various remote package repositories.

Choose one from the list and click on '''Finish.'''

|-
|Click Install
| Click on '''Install'''.

It will install the '''beamer.cls '''package

|-
|Dialog box
| Once again the '''Package Installation '''dialog box will open.

|-
| Point to '''pgfcore.sty'''
|It will prompt to install the missing package '''pgfcore.sty.'''

|-
| Uncheck the checkbox
|You may uncheck the option '''Always show this dialog before installing packages'''.

If you do this, '''MikTeX''' will not prompt you again, if it encounters a missing package.

|-
| Click Install
|Click on '''Install.'''

|-
|
|Now if there any more missing packages, it will automatically install it, without asking for your permission.

|-
| Point to the output side.
|Once the installation completes, it will finish the compilation and open the '''pdf''' output.

We can see that we have successfully compiled a '''Beamer''' document.

|-
|Click on Start >>All programs >>'''MikTeX'''>> Maintenance(Admin) >> Package Manager(Admin)

| Now let us see the second method of installing missing packages.

Click on the '''Windows''' start button.

Click on '''All Programs'''.

Click on '''MikTeX2.9'''

Click on '''Maintenance (Admin)'''

Cick on '''Package Manager (Admin)'''

|-
|
| It will show a list of various packages available

Now let us take a look at this list.

|-
| Point to the columns
|There are six columns in this list.

These are '''Name, Category, Size, Packaged date, Installed on date''' and '''Title'''.

|-
|
|The '''Installed on''' column is very important to us.

|-
| Point to the blank column entries
|The packages for which this column is blank indicates that these packages are not installed.

|-
|
|Let us see how to install a particular package.

|-
|check this step of proxy authentication
| Let me choose the package '''abc''', for example.

|-
| Point to the plus button
|Notice that the moment I choose the package, the '''plus''' button on the top left side gets enabled.

|-
| Click on the plus button
|The '''plus''' button is the '''install''' button.

Click on the '''plus''' button.

|-
|
|A window will open which will list the number of packages you have chosen to install or uninstall.

|-
| Click Proceed
|Click on '''Proceed'''.

|-
| Proxy dialog box
|Since I have configured a '''proxy''' network connection, it will prompt me for the '''proxy username''' and '''password'''.

|-
| Type proxy
|Let me type my '''username''' and '''password'''

|-
| Click Ok
|Click on '''Ok'''

|-
|Window

| A window will open which will show the download progress of the package selected for installation.

It may happen that it fails to download the requested package due to remote server connectivity issues.

In that case, change the package repository and try again.

|-
| Click Close
|We can see that the installation of selected package is completed.

Click on '''Close'''.

|-
| Point to the entry
|The package list will get refreshed.

|-
|
| Now let us compile a '''Beamer''' document.

|-
| On slide

|Beamer package by default is not included in the '''MikTeX''' setup that we have installed.

This means that we have to
*download it from some source and
*add it to our current '''MikTeX''' distribution

|-
| On slide

|There are two ways of installing a missing package.

One way is to install it on the fly while we are compiling a '''LaTeX''' document

This '''LaTeX''' document will typically require a package not available in your '''MikTeX''' distribution.

Other way, is to manually choose and install a package using '''Package''' '''Manager''' of '''MikTeX'''.

|-
|
|Let us see the first method.

|-
|
| We will
* open and compile a '''LaTeX''' document,
* which requires '''MikTeX'''
* to install packages from the '''internet'''.

|-
| Close '''TeXworks'''
|First close the '''TeXworks''' editor.

|-
|Click on Start>> All programs >> '''MikTeX'''

| It is required that we open the '''tex''' file with administrator privileges.

Click on the '''start''' button.

Then click on '''All programs'''.

Click on '''MikTeX2.9'''

|-
| Right-click '''TeXworks''' >> Run as Administrator
|Right click on '''TeXworks''' and choose '''Run as Administrator'''

This will launch the '''TeXworks''' editor with '''administrator''' privileges.

|-
|Click on File>> Open>> beamer.tex
| Now click on '''File.'''

Then click on '''Open'''

Choose the file '''beamer.tex'''

|-
|Press Ctrl+T keys
| Press '''Ctrl''' and '''t''' keys together to start the compilation.

If you do this, '''MikTeX''' will not prompt you again, if it encounters a missing package.

|-
| Click Install
|Click on '''Install.'''

|-
|
|Now if there any more missing packages, it will automatically install it, without asking for your permission.

|-
| Point to the output side.
|Once the installation completes, it will finish the compilation and open the '''pdf''' output.

We can see that we have successfully compiled a '''Beamer''' document.

|-
|Click on Start >>All programs >>'''MikTeX'''>> Maintenance(Admin) >> Package Manager(Admin)

| Now let us see the second method of installing missing packages.

Click on the '''Windows''' start button.

Click on '''All Programs'''.

Click on '''MikTeX2.9'''

Click on '''Maintenance (Admin)'''

Cick on '''Package Manager (Admin)'''

|-
| Type proxy
|Let me type my '''username''' and '''password'''

|-
| Click Ok
|Click on '''Ok'''

|-
|Window

| A window will open which will show the download progress of the package selected for installation.

It may happen that it fails to download the requested package due to remote server connectivity issues.

In that case, change the package repository and try again.

|-
| Click Close
|We can see that the installation of selected package is completed.

Click on '''Close'''.

|-
| Point to the entry
|The package list will get refreshed.

|On slide
| Dear Friends,

Welcome to the spoken tutorial on '''“LaTeX on Windows using TeXworks”'''

|-
|On slide

| In this tutorial we will learn to,
# Download and install '''MikTeX'''
# Write basic '''LaTeX''' documents using '''TeXworks'''
# Configure '''MikTeX''' to download missing packages

|-
|On slide
| To record this tutorial, I am using '''Windows7 '''operating system and MikTeX2.9

|-
|On slide

| Let us now see the salient features of '''TeXworks'''

# It is platform independent
# It has an embedded pdf reader
# It supports Indian language typesetting

|-
|On slide

| Before we start with '''TeXworks''', we have to install '''MikTeX'''.

'''MikTeX''' is an up-to-date implementation of '''TeX/LaTeX''' and related programs for '''Windows'''.

It contains the necessary packages to create basic documents in '''LaTeX '''on '''Windows'''

Moreover, '''TeXworks''' is a default editor available with '''MikTeX''' installation.

|-
| On the browser
|Go to the website [http://www.miktex.org/ www.]'''miktex'''[http://www.miktex.org/ .org]

|-
|Click on that link

| Click on the download link for recommended '''MikTeX''' installer.

This will download the '''MikTeX''' installer.

|-
| Choose Desktop in Save location

|Download and save it on your '''Desktop.'''

It is a large file, about 154 mega bytes.

Hence, it will take some time to download.

|-
| Switch to the Desktop and point to the file.
|I have already downloaded this file. Here it is.

|-
|Double-click >> click Run

| Double click on this file to start the installation.

Check the check box and click on '''Next'''.

Choose all default options.

|-
| Show the installation process

|The installation will take around 5 to 10 minutes.

I have already installed '''MikTeX''' on my computer.

Hence I will not proceed with the installation.

|-
|
|After successfully installing '''MikTeX''' on your computer,

let us see how to use the '''TeXworks''' editor which comes with '''MikTeX.'''

|-
|Click on Windows>>All programs >> '''MikTeX'''>>'''TeXworks'''

| Click on the '''Windows start''' button.

Click on '''All Programs'''.

Click on '''MikTeX2.9'''

Click on '''TeXworks'''

|-
|
| '''TeXworks''' editor will open.

Let me open an already existing '''LaTeX''' document.

|-
| Click on File >> Open >> hello.tex
|I will click on '''File,''' then click on '''Open''' and choose the directory.

Then I will open the file '''hello.tex'''.

|-
|Point to some of the coloured text

Point also to the user content

| You can see that the text written in the file is colored.

This is called '''syntax''' '''highlighting'''.

It helps the user differentiate between the user content and the '''LaTeX''' syntax.

|-
|
|In case the '''LaTeX''' syntax is not highlighted, do the following.

|-
|Click on Format
| In the '''TeXworks''' window, click on '''Format''' button available on the '''Menu bar'''.

|-
|Select '''Syntax Colouring'''>>'''LaTeX'''.
| Select '''Syntax Colouring''' and then click on '''LaTeX'''.

|-
|
| If you want '''TeXworks''' to apply '''syntax highlighting''' every time you create a '''LaTeX''' document, do the following

|-
| Click on '''Edit''' >> '''Preferences'''
|On the '''menu''' bar, click on '''Edit''' and then click on '''Preferences'''.

|-
| Editor tab>> dropdown>> Syntax Colouring
|In the '''Editor''' tab, click on the dropdown button which gives options for '''Syntax Colouring'''.

|-
| Choose '''LaTeX'''>>Ok
|Choose '''LaTeX''' and then click on '''Ok.'''

|-
|
|In this way, '''syntax''' '''highlighting''' will be applied to all documents created in the future.

|-
|
|Now we are ready to compile our '''LaTeX''' document.

|-
|Press Ctrl+T keys
| Press '''Ctrl''' and '''t''' keys together to start the compilation.

|-
|
| Once the document is compiled without errors, the resulting '''pdf''' will be opened.

|-
| Point to the pdf document
|Note that this '''pdf''' reader comes along with '''TeXworks.'''

It is the default '''pdf''' reader used by '''TeXworks''' to display the compiled '''pdf''' documents.

Single Board Heater System

Rupakrokade:

A single-board heater system is a low cost, open source, lab-in-a-box setup. It consists of a heater assembly, fan, temperature sensor, ATmega16 microcontroller and associated circuitry. A block diagram representation of the same is shown in figure below. A stainless steel blade whose temperature has to be controlled serves as the plant. Nichrome helical coil with 20 turns kept at a small distance from the steel blade, acts as the heater element. AD590, a monolithic integrated circuit temperature transducer, is soldered beneath the steel plate. A computer fan, a low cost and commercially off the shelf component, is used to cool the plate from below.

[[File:SBHSblkdig.jpg|650px]] [[File:Sbhs-new.jpg|500px]]

The plant has a small time constant, less than a minute, that allows completion of an experiment in a short time. This in turn facilitates performance of a large number of experiments in a single laboratory session. The speed of response not being too fast allows the measurements to be seen with naked eye, as it happens in industrial systems. It also demonstrates other measurement issues, such as, noise. The codes for hardware interface and control experiments, and manuals are available at [http://fossee.in/moodle http://fossee.in/moodle].

In these series of tutorials we would talk about the hardware device, its features and components. We would also talk about how to access this device using [http://spoken-tutorial.org/wiki/index.php/Scilab Scilab]. These tutorials are made for both [http://spoken-tutorial.org/wiki/index.php/Ubuntu Ubuntu-Linux] as well as Windows Operating System. We would also see how to access the SBHS device remotely under Virtual Labs project.

This device aims at serving a small portable lab for an individual or an institute. The application of this device is in the Control Systems area of Engineering. All Undergraduate level experiments and most Post graduate level control experiments can be performed on the SBHS device. The user is however expected to have a fair understanding of Control System terminologies, for example Transfer Function.

The Spoken Tutorial Effort for SBHS is being contributed by Anuradha Amrutkar, Shalini Shrivastava and Rupak Rokade from IIT Bombay. The preliminary work on SBHS was contributed by Inderpreet Arora and Kaushik Venkata Belusonti, former students of IIT Bombay.

Locate the '''ports (COM & LPT)''' option.

Here it is

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| Double click on the '''Ports(COM & LPT)''' option

Else look for '''USB Serial Port'''.

For '''RS232''' connection, the port number mostly remains '''COM1'''.

For '''USB''' connection, it may change to some other number.

Note down the appropriate '''COM''' number.

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| Click on the identified COM port number

Sometimes the '''COM''' port number you get after connecting a '''USB''' cable is a two-digit number.

The '''serial tool box''' which connects your board and computer, can handle only single-digit port number.

Hence, it is necessary to change your '''COM''' port number.

|-

Let me switch to the slides.

The '''Fan, Heater '''and''' Temperature''' are displayed on the '''SBHS''' display as shown in the image.

If this is not the case, then it means that '''Scilab''' is not communicating with '''SBHS'''.

|-

To '''reset''', press the '''Reset''' button for 1 or 2 seconds and then release it.

The '''reset''' operation makes '''Heat''' 0% and '''Fan''' 100%.

However '''0''' is displayed for both on the '''LCD'''.

Else look for '''USB Serial Port'''.

For '''RS232''' connection, the port number mostly remains '''COM1'''.

For '''USB''' connection, it may change to some other number.

Note down the appropriate '''COM''' number.

|-

Sometimes the '''COM''' port number you get after connecting a '''USB''' cable is a two-digit number.

The '''serial tool box''' which connects your board and computer, can handle only single-digit port number.

Hence, it is necessary to change your '''COM''' port number.

The '''dead time''' and '''time constant''' is calculated from the time axis.

| style="background-color:#ffffff;border:1pt solid #000000;padding:0.097cm;"| Replicate this on the '''SBHS''' output figure we just saved on the '''Desktop.'''

Let me open this file

I have used '''paint brush''' which is a default image editing tool on '''Windows'''

I have got the values of

* gain equal to 2.78
* '''dead time''' equal to x seconds
* and '''time constant''' equal to y seconds

Note that these are all approximate values.

The values depend on the accuracy with which you draw the tangent line at the inflection point.

| style="background-color:#ffffff;border:1pt solid #000000;padding:0.097cm;"| After you get the required values, refer to the table given by '''Ziegler-Nichols''' to calculate the value of '''PID'''.

Let me switch to the slides

For a '''proportional''' '''controller''', we need to calculate only the value of '''proportional''' gain

In my case the value of '''proportional''' gain comes out to be X

But a unity gain will have no noticeable effect.

Hence I approximate the value to 2

Now let us see how to implement the '''proportional''' '''controller''' on SBHS

We would modify the step test code for this

In the next line type '''global''', leave a space and then type '''temp''' and press '''Enter'''

In the next line type '''err''' '''equal''' '''to''' '''setpoint''' '''minus''' '''temp'''

Add semicolon at the end and press '''Enter'''

In the next line type '''heat equal to 2''' multiplied by '''err'''

Double click on the file '''run'''

This will open the '''SBHS''' client application

Login with your '''username''' and '''password'''

Make sure you are logging in at the booked '''slot''' time

Expect the message '''Ready to execute Scilab code'''

Type '''getd space dot dot slash common underscore files'''

Press '''enter'''

Switch to the '''Scilab''' editor

execute the file '''proportional.sce'''

If the network is fine then it will automatically open the '''xcos''' window with

'''proportional''' '''controller''' '''xcos''' diagram

Execute the '''xcos''' diagram and expect a plot window

|-

| style="background-color:#ffffff;border:1pt solid #000000;padding:0.097cm;"| The plot window will have three plots '''heat fan temperature'''

Setpoint will also be plotted in the temperature graph

Observe that the '''proportional''' '''controller''' computes the value of '''heat''' in order to achieve the '''setpoint''' value of temperature

Run this experiment long enough to observe what happens after a step change in '''setpoint''' occurs.

I will now pause this recording until the experiment is executed for sufficient time

You can observe that the '''proportional''' '''controller''' inherently has the property of offset

A '''proportional''' '''controller''' will always have an offset between the setpoint value and the actual value

If you modify and save the codes in a higher version of scilab then these codes cannot be re-used in '''Scilab 5.3.3'''

This is because a software is always backward-compatible, never forward-compatible.

I have already installed '''Scilab 5.3.3.'''

Now the next step is to download the experiment '''Scilab''' code.

SBHS is a 3000 rupee device with its hardware design and codes released as an open source. However, please note that the actual price during purchase may vary.

An open source software is used to interface SBHS.

More details can be sought from: sbhs.os-hardware.in

Hence, one can do realistic experiment in 10 minutes

This setup is also available for remote access under Virtual labs project

One can access it remotely and get a feel for it.

Later the user can buy it or assemble it and set it up as a lab at college or at home.

# Power Supply
# 8-bit micro-controller
# Display
# Fan
# Heater Assembly
# Temperature Sensor
# Instrumentation amplifier and associated circuitry
# ISP
# Serial and USB port

We would now see a brief explanation of the various blocks in SBHS.

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| Show slide
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| First we will see the Power Supply.

The Power supply is basically a 12V 400 watt SMPS.

This 12V supply is used directly but most of the circuitry requires 5V supply.

Hence separate voltage regulators are used wherever necessary.

Also, to avoid any ambiguous temperature readings due to power supply fluctuations, the voltage regulators for System and sensor are kept separate.

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| Show slide
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| Next is Micro-controller.

An 8-bit ATmega16 micro-controller is used.

Micro-controller plays a very important role.

It controls every single hardware present on the SBHS, directly or indirectly.

It executes various tasks like

# Setting up communication between computer and SBHS
# Controlling the amount of current passing through the heater coil
# Controlling the fan speed
# Reading the temperature value
# Displaying parameter values and various other necessary operations.

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| Show slide
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| Next comes the Heater and Fan.

The heater assembly consist of a metal plate placed about 3.5 mm away from a nichrome wire coil.

When current passes through the coil, the coil gets heated.

This heat is transfered to the metal plate through convection increasing its temperature.

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| Show slide
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| The fan used is a small regular computer fan.

It is used for cooling the heated metal plate.

Due to some tried and tested reasons, it is placed below the heater.

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| Show slide
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| Next comes the Driver block.

This is nothing but a device which varies the amount of power delivered to the fan and heater.

MOSFETS are used for the same.

MOSFETS are operated as per the commands given by the micro-controller.

These MOSFET's are actually switched at some PWM frequency.

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| Show slide
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| Now we will talk about the Temperature sensor.

AD590 is the Temperature sensor used for sensing the temperature of the heated plate.

The output of this sensor is in micro ampere per kelvin.

The operating temperature ranges from -55 to 150 degree Celsius.

Moreover, it does not requires any further process of linearization.

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| Show slide
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| Next we will see Instrumentation amplifier.

Instrumentation amplifier is used for signal conditioning of the signal generated by AD590.

It also provides good input impedance for the temperature sensor

Hence, the signal generated by the sensor is not attenuated during signal conditioning.

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| Show slide
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| The Display and Indicators block.

Display constitutes of a 16x2 LCD display.

This means that the display is capable of displaying two lines of 16 characters each.

No separate controller is required since it has its own in-built controller.

It is used for displaying various parameters like temperature, fan, heater and machine ID (MID) .

It is operated in 4-bit mode.

The indicators include various on-board LEDs.

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| Show slide
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| Next we have Serial Voltage Level Converter block.

Used for conversion of signals from serial to TTL and vice versa

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| Show slide
