My idea is to generate 2, 3 or 4 PWM signals with the MiniZed board and using Vivado and Vitis, but any example with another board is useful for me.
I found a good tutorial by Adam Taylor to generate a simple PWM signal: https://www.hackster.io/adam-taylor/mini-but-mighty-the-minized-and-vitis-for-motor-control-9c376b
However, for more PWM signals I have to make changes to the hardware (Vivado) and the software (Vitis). Does anyone know what changes need to be made?
Hi guillengap you can use the AXI_Timer IP in the Programmable Logic area.
I made a tutorial for the Spartan-7. I think it will be easily portable to the minized.
I also made several PID controllers and a support library.
A simple App using the library
Another source of inspiration may be the Digilent drivers, although I think my solution with the AXI Timer is simpler and better supported by Vitis/Vivado.

In order to know how to use the Digilent's vivado library you can look at my last blog:
