I am trying to set up a minimal example that makes use of Model-Based Design Toolbox to generate PWM. If I build the model below and flash it I only have noice on the PTA2 pin. Whereas if I manually Programm it up it works (so the hardware seems to be fine.)
Hello [email protected],
Your model does not generates the signals on the pins because the timer is not started. There are some application, like Motor Control that requires to initialize the PWM at a certain moment in the application. In order to enable the timer, go to the PWM block, check the "Show advanced options" and then check the "Start PWM signals generation immediately after initialization". Should have been checked by default, but now we know the problem :smileygrin:.
If you need to start the timer at a certain moment inside the code, you need to add the following block, select the module and the Action Enable.
Hope this helps,

Hello [email protected],
We are talking about the same mot file? So if you manually program the generated mot file, it runs? Are you sure that the generated code reaches the board automatically? Because from your screenshot, the Download Code after Build is not checked, so the model will generated only the mot file and will not flash the mot on the controller.
Consider checking the the Download Code after Build, select OpenSDA if you are trying to run this code on the EVB or you have an OpenSDA and then select the correct Drive Name.
If my understanding is wrong, consider attaching your model to have a closer look on your settings.
Hope this helps you,
Marius
