I am trying to get some high speed PWM DMA code working on TIM4 CH3 and TIM4 CH4. I can get theTIM4 CH3 signal on D10 but the TIM4 CH4 on D9 doesn't output anything. Is there some hardware limitation ?
PD15 TIM4_CH4 seem viable, see if you can drive it up/down as a GPIO, proper AF settings, etc.
It is exported to two pins on the board CN12.48 and CN7.18 (D9)
