All pins are PWM now , all at once (STM32)

Had it working now for a while, the LED drivers im pwm-ing dont care about a bit of jitter so i cranked the frequency up to 100kHz.

I also modified the buffer to have 10% steps instead of 1%.

TODO: we still have the DMA complete and half complete interrupts, im sure i could dissable the half completed interrupts, so i bother even less my microprocessor
