I am trying a Simulink example called Asynchronous Scheduling for STM32F4-Discovery Board from the documentation on the Embedded Coder Support Package for STMicroelectronics Discovery Boards. I have followed all the required steps. I have been using a USB type A to Mini-B cable and a USB TTL-232 cable - TTL-232R 3.3V and it is not working. I can run and deploy my code on my STM32F4 and I am able to run my simulation without any errors from the diagnostic viewer. My problem is that I do not have any voltage value in my scope and any voltage value in my data inspector. Is there some other documentation on this example? Is there someone who knows what could be the source of my error?
