swap PWM H and PWM L Pins on STM32F4

Hi, let's say someone (maybe me) made their own VESC based hardware and was so dumb to mess up the pins from the stm32 to the gate driver... so now STM-L -> GateDriver-H and STM-H -> GateDriver-L same for phase U ,V and W.

I don't want to make a new PCB if there is a chance to swap the pins in software or maybe it's sufficient to change the ADC timer from Up to down Count ? 

 

 

thanks : Harry

It was not advised but it could work without changing pins.

You may change the pin assightments in hw config files.

Just look inside hwconfig as a ref. Example palta..h
