Bare Metal Timer PWM generation using DMA

[DJ1]

Hi guys, Can anyone list out a few steps which need to be followed for bare-metal code generation of using Timer in DMA for PWM generation. 

Thanks!

HAL stuff is hard to read and get through, but (most of) it works.
So you just need lots of concentration and perseverance...

When starting from scratch:
- read the RM
- "collect" relevant registers
- start simple: no settings, just a fixed frequency & duty cycle square
- then add stuff...

PS: DMA is one of the few things I use HAL, many of the HAL_DMA_Start functions are quite "slim" compared to the normal HAL stuff

Which STM32?

Show.

PS. +1 to what @LCE  wrote above.
