Arduino Simulation with Proteus 

We 'll show how to simulate the celebrated open-source electronics prototyping platform Arduino with Proteus .You can find other informations, project files and arduino software at its homepage.

  

 Let 's run ISIS Schematic:

To simulate the core of Arduino platform we need only a few components: the atmega328P Microcontroller, a Crystal and two Capacitors.Let' s look for these devices in the library:

Click on "P" button and write atmega as keyword:

 Double click on the model and this appears under Devices panel:

  

Same operations for the Crystal and Capacitor:

 

Now we have all the components in the panel Devices:

  

Let 's click on the components and place them on the layout:

 

  Right click on the component and select Rotate .. to place it correctly:

  

 Double click on the crystal and set the frequency to 16Mhz:

  

Double click on capacitors and set the values:

  

Let 's start wiring the circuit:

Click on "Terminals Mode" on the left toolbar and select the ground reference

  

Now select the power source

  

Connect the pins to the power source as in the picture below:

  

Finally we get the Arduino schematic:

 After downloading the software from the Arduino site run the program:

  

The Arduino main window appears

  

Let 's choose to load the blink example from File menu:

The window shows the C code of the program:

  

This program simply turn on and turn off a led with a period of 1 second for every function.Let's save the program in a directory of our choice:

  

  

The program is saved in pde format:

  

Come back to the program and click on the Verify button to check the correct syntax:

Once the syntax has been verified make sure that "Arduino Duemilanove or Nano w/ ATmega 328" is selected from Tools/Board menu:

  

Now click on the Upload button

  

At the end of the process an error message appears, because Arduino board is not connected, we can ignore it:

  

Instead make sure that applet directory has been created  in the directory of the pde file:

Let's open applet directory and we can see the hex file generated:

  

Now come back to the Arduino schematic and double click on the microcontroller, in the window that pops up select the hex file:

  

Select the following settings:

  

  

We' re ready to simulate.Click on play button in the bottom left corner of thelayout:

  

license VSM for AVR is required to enable the simulation.As result of running program the pin 19 of microcontroller start blinking with a period of 1 second
