STM32F334 and High Speed PWM

Hello!

Is it possible to implement the STM32F334 HRTIM PWM library?
How do I call the HAL library?
Linked Document Chapter 2.1, A Single PWM Generation Example.

HRTIM cookbook:http://www.st.com/resource/en/applicati ... 121475.pdf

Hi,
The stm32f3xx_hal_hrtim.h header file is linked into the Flowcode build, so you should be able to call the HAL functions from a C icon

Can you help me with an example?
Thanks!

Here I just did a copy'n'paste from the HRTIM cookbook, not that I'm confirming that it works, I've never tried it, but the C code is valid ...

The empty project is also bad.

Attached update to go into your Flowcode installation FCD\ARM\ directory.

Hello,

I've created a demo program for HRTIM PWM.
There may be a terrible part of the code. (spaghetti code): D
I do not really understand C programming.

Hi thanks for digging into this. I am going to be playing with pwm on the 446re chip. This is a big help.
