STM32: Allow specifying the GPIO speed on PWM pins #337

Closed WickedShell closed 4 years ago

This allows you to set the GPIO output speed using the PWM wrapper package, rather then use the hard coded maximum output speed. It's done as an optional argument, so this shouldn't be a breaking or behavioral change for anyone.

I tested this on a STM32F405, using a 10KHz PWM at a variety of duty cycles, and saw the expected change in output slew speed. I can provide some scope captures if needed.

@Fabien-Chouteau I sorta figured the bot would complain either way :) My name is Michael du Breuil.
