I changed the "standart" 0,001Ohm shunts with 0,0005Ohm ones because the drv8302 got damaged at above 200A peak. I installed the firmware for this shunts but it don`t work propably. Sometimes I can spinn the motor so it seems pretty close to work. motordetection always foult and FOC detection leads to wrong motor resistant and inductivity.(about faktor 10 both to high)
So what else to change to get the hardware run?
Input current seems to be not measured, too and virtuell GND sometimes went up when the motor is not spinning.
