I have a PWM implementation for the STM32 (currently F3 & F7) but I'm not happy with it - which is why there currently is no PR.
Most of what I want to change is the use of the backend library, using the LL api instead of HAL. All STM32 bindings I could find in mynewt are based on the HAL library ... Is it acceptable to base a peripheral library on the LL api or is that not something to be done in mynewt? Have fun, Markus
