| 00:01 | Welcome to the Spoken tutorial on Arduino Programming with OpenModelica. |
| 00:08 | In this tutorial, we will learn about Arduino OpenModelica toolbox |
| 00:16 | Interfacing Arduino with OpenModelica |
| 00:21 | To record this tutorial, I’m using |
| 00:25 | Ubuntu Linux OS version 18.04 |
| 00:30 | Arduino Shield and Arduino Uno Board |
| 00:35 | To follow this tutorial, you should go through the below Arduino Spoken tutorial. |
| 00:42 | Getting ready for Arduino FLOSS. |
| 00:46 | In the above tutorial, you will learn |
| 00:50 | How to download the e-book and code files required for the experiments. |
| 00:56 | How to upload and compile Arduino programs in Arduino IDE. |
| 01:02 | About FLOSS Firmware |
| 01:05 | If you are not familiar with OpenModelica, go through the spoken tutorials on this website. |
| 01:13 | You will learn about |
| 01:15 | Introduction to OpenModelica |
| 01:18 | OpenModelica interface |
| 01:21 | Various perspectives and Simulation |
| 01:26 | I have downloaded the e-book on my Desktop. |
| 01:30 | Let us open the book Microcontroller Programming with Arduino and OpenModelica. |
| 01:38 | Refer to chapter 3 in the book. |
| 01:42 | Follow the steps and do the installation of Arduino IDE and OpenModelica depending upon your OS. |
| 01:51 | Installation steps are given for Windows and Linux OS. |
| 01:57 | The experiments that are covered in the book are tested in Ubuntu Linux 18.04 and Windows 10 OS. |
| 02:07 | Connect the Arduino UNO board with Arduino shield to the USB port of the computer |
| 02:15 | Note the below points: |
| 02:18 | 1. Launch Arduino IDE |
| 02:21 | 2. Check the port |
| 02:24 | 3. Upload the Floss firmware
That is, in the Arduino IDE, upload the file available at Origin slash tools slash floss hyphen firmware slash floss hyphen firmware dot ino |
| 02:40 | As discussed in the earlier tutorial, the above steps have to be done before proceeding further. |
| 02:48 | By default, OpenModelica does not have the capability to connect to Arduino. |
| 02:55 | All such add-on functionalities are added to OpenModelica using the toolbox. |
| 03:02 | These functions are required to run various experiments on the Arduino UNO board. |
| 03:09 | It also establishes a serial communication with Arduino. |
| 03:15 | We have different toolboxes for Windows and Linux OS. |
| 03:21 | The Arduino-OpenModelica toolbox can be found inside the directory
Origin slash tools slash OpenModelica slash windows or Origin slash tools slash OpenModelica slash linux |
| 03:40 | First we have to load the toolbox depending upon your OS. |
| 03:46 | I’ll show how to load the toolbox in Linux. |
| 03:51 | Open the terminal by pressing Ctrl+Alt+T keys. |
| 03:57 | I have installed Arduino IDE and OpenModelica 1.1.7 in my Linux system as specified in the book. |
| 04:08 | Go to the folder where OpenModelica is installed as shown and launch the OpenModelica. |
| 04:16 | Next, we have to load the Arduino OpenModelica toolbox. |
| 04:22 | Click on File and then click on the OpenModel slash Library File(s) option. |
| 04:30 | Navigate to Origin slash tools slash openmodelica slash linux. |
| 04:37 | Select Arduino.mo and test_firmware.mo and click Open. |
| 04:44 | In OMEdit, under the Libraries panel, look for three new libraries. |
| 04:51 | They are Arduino, Modelica_Synchronous, Modelica_DeviceDrivers and test_firmware.mo. |
| 05:04 | This confirms that the Arduino OpenModelica toolbox has been loaded successfully. |
| 05:12 | Next let us run the OpenModelica program in chapter 8. That is, Interfacing a Thermistor. |
| 05:21 | This program will read and display the thermistor values. |
| 05:26 | Switch back to the OmEdit interface. |
| 05:30 | The codes are available inside the Arduino OpenModelica toolbox under the Libraries panel. |
| 05:38 | Select Arduino -> SerialCommunication -> Examples -> thermistor -> therm_read. |
| 05:48 | Double-click on the file to open. |
| 05:51 | Click on the Simulate button on the top right corner. |
| 05:56 | Click on the Ok button in the simulation setup window. |
| 06:01 | We can see the thermistor value displayed on the screen. |
| 06:06 | Rub the thermistor with the fingertips. |
| 06:10 | It will transfer heat from the person's finger, thereby raising the temperature of the thermistor. |
| 06:17 | Accordingly, we can observe the change in the thermistor values. |
| 06:23 | Points to remember:
Whenever you plug the Arduino Uno board into the computer, check for the port. |
| 06:33 | Then execute the commands required for read-write permission. |
| 06:39 | Don’t upload any Arduino program after uploading the FLOSS firmware to Arduino Uno board. |
| 06:47 | This would overwrite the FLOSS firmware. |
| 06:51 | Check if the Arduino-OpenModelica toolbox is properly running or not. |
| 06:58 | You have to load the Arduino OpenModelica toolbox each time when you launch the OMEdit. |
| 07:06 | With this we come to the end of this tutorial. Let us summarize. |
| 07:13 | In this tutorial, we learnt about
