hardware-prerequisite.jpg
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Connect''' SMPS''' and '''USBasp''' to the '''Mainboard''' as shown in the picture.

Keep these connections throughout this tutorial.

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Open the LDmicro
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Let us open '''LDmicro'''.

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"|
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| First we’ll see the working of an '''OSR''' instruction.

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Insert ‘Instructions -> Insert Contact’ >> Place the cursor to the right of the contact >> Insert ‘Instructions -> Insert Coil’
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Insert a '''Contact''' and a '''Coil''' as shown.

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Double-click on contact >> Type switch in name box >> Click OK button

Double click on the coil >> Rename it as ‘LED1’ >> Click OK button
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Rename the Contact as '''‘switch’''' and rename the Coil as '''‘LED’'''.

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Place the cursor to the right of the contact >> Click ‘Instructions -> Insert OSR instruction’
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Add an '''OSR''' instruction to the right of '''Xswitch'''.

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"|
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| We will now check the working of this logic.

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Click Simulate -> Simulation mode >> Click Simulate -> Real-time simulation
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Let us turn on the simulation mode.

For that, click '''Simulate''' and then on '''Simulation mode.'''

Next, start real-time simulation as shown.

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"|
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Observe the state of '''Xswitch''' and '''YLED''' in the I/O list.

Initially the state of both '''Xswitch''' and '''YLED''' are 0.

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Double-click on ‘Xswitch’ in the I/O list
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Change the state of '''‘Xswitch’''' to 1.

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Highlight rung
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| We can notice that '''YLED''' energises for a brief moment.

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"|
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| This is because '''OSR''' generates a pulse on each rising edge of its input signal.

The pulse width is equal to one '''PLC''' scan cycle.

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"|
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| For a close observation, let us increase the '''PLC''' cycle time.

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Click on Simulate -> Halt simulation >> Click on Simulate -> Simulation Mode
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Now, turn off the simulation mode.

For that, click '''Simulate''' and then on '''Halt Simulation.'''

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Click Simulate -> Simulation mode >>

Click Simulate -> Real-time simulation
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Now again start real-time simulation.

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Double-click on ‘Xswitch’
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Change the state of '''Xswitch''' to 1.

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Highlight rung
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| We can observe that within 3s '''YLED '''will get energised.

Also it stays energised for about 3 seconds.

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Double-click on ‘Xswitch’ in the I/O list

Highlight state of YLED in the I/O list
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| After that, change the state of '''Xswitch''' to 0.

We can see that the falling edge has no effect on the state of '''YLED'''.

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Click on Simulate -> Halt simulation >> Click on Simulate -> Simulation Mode
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Turn off the simulation mode as shown.

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"|
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Now let us compile the logic.

The detailed steps on how to compile and save the logic are explained in the earlier tutorials.

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Click on Settings >> Click on Microcontroller >> Select AVR ATmega16 40-PDIP

Click on Settings >> Click on MCU parameters >> Change Crystal frequency to 16
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Click on '''Settings''' and select the microcontroller '''AVR ATmega16 40-PDIP.'''

Adjust its parameters as shown here.

Let the cycle time be 3000ms and change crystal frequency to 16 MHz.

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Double-click on Xswitch in I/O list >> Select PC0 >> Click OK button

Double-click on YLED in I/O list >> Select PA0 >> Click OK button
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Assign pin '''PC0''' to '''Xswitch.'''

Then assign pin '''PA0''' to '''YLED'''.

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Click on Compile >> Click on Compile >> Go to Desktop/LDmicro folder >> Rename it as ‘osr.hex’ >> Click on Save.

Click OK button
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Compile the logic as '''‘osr.hex’.'''

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Click on File >> Click on Save >> Go to Desktop/LDmicro folder >> Rename it as ‘osr.ld’ >> Click on Save
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Save the ladder diagram as '''osr.ld''' as shown.

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"|
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| We will now see the working of this logic on hardware.

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Connect Mainboard to PC using USBasp

laptop-usbasp.jpg

| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Connect the '''Mainboard''' to your laptop using '''USBasp'''.

This will prevent any hardware damage.

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| osr.png
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Let us see the connection details now.

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| osr.png
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Connect '''GND''' pin of the red LED of '''Traffic Light''' module to '''GND''' of the '''Mainboard'''.

Then connect '''+5V pin''' of the red LED to '''PA0''' pin of the '''Mainboard'''.

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| osr.png
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Connect '''GND''' and 5V of '''switchboard''' to GND and 5V of the '''Mainboard''' respectively.

Then connect '''NO1''' of the '''Switchboard''' to '''PC0''' of the '''Mainboard'''.

Make the connections as shown in the picture.

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"|

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Point to the output
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Press NO1 for about 3 seconds.

After releasing the switch NO1, the red LED glows for about 3 seconds.

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"|
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| The time for which the LED glows depends on PLC cycle time or scan cycle.

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"|
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Turn off the power supply.

Remove the connections made for this example.

|-

| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Now, we’ll look at the working of '''OSF''' instruction.

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Switch back to LDmicro
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Switch back to '''LDmicro'''.

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"|
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Instead of creating a new file, we will make changes in the previous file itself.

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"|
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| We will replace '''OSR''' with '''OSF''' instruction.

| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Initially the state of both '''Xswitch''' and '''YLED''' are 0

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Double click on Xswitch
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Now, change the state of '''Xswitch''' to 1.

We can observe there is no change in the state of '''YLED'''.

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"|
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Change the state of '''Xswitch''' to 0.

We can observe that the state of '''YLED''' changes to 1 for about 3 seconds.

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Highlight cycle time at the bottom of the screen
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Remember that, we have changed the cycle time to 3s.

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Highlight the rung
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Thus '''OSF''' generates the pulse on each falling edge of its input signal.

Note that rising edge doesn’t have any effect on it.

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Click on Simulate -> Halt simulation >> Click on Simulate -> Simulation Mode
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Turn off the simulation mode as shown.

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"|
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Now let us compile the logic.

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Highlight I/O list and status bar
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| We can observe that microcontroller and its parameters are already set.

Pin assignment is also already done.

|-
| style="background-color:#ffffff;border:1pt solid #000001;padding:0.176cm;"| Click on Compile >> Click on Compile As >> Go to Desktop/LDmicro folder >> Rename it as ‘osf.hex’ >> Click on Save.

Click OK button
