You will find sample code in the repositories for STM32, e.g. on Github in some examples for NUCLEO-G474RE.

Please take a look at the AN4539 - HRTIM cookbook.

Hi Anand,

I use all 12 HRTIMs channels in my NUCLEO-G474RE port of MIcroPython.

https://forum.micropython.org/viewtopic.php?f=3&t=9082

This is a high resolution PWM application where I use a custom modg4ex.c to add HRTIM support. You can get a lot of mileage with the STM32CubeMX app to generate the initial 'C' code. The CubeMX generates brute force inline code for each channel so you need to refactor it into subroutines to shorten it up. The G474 is still a new beast so the cookbook and examples are of limited help.

best regards, RealSparky from the micropython forum
