Hi,
I wanted to have a quick test of the wiper motor in combination with pypilot. So I decided to use the vnh2sp30 instead of building my own h bridge.
But I get SYNC FWD_FAULT so the wiper motor can only turn in one direction. The only part for FWD_FAULT that I could find is reading the
fwd_fault_pin. I measured that pin...it's HIGH, so it souldn't show FWD_FAULT, right? Any ideas?
In servo.py I can see FWD_FAULT=4096*1 # overcurrent faults does that meen, that FWD_FAULT is shown on overcurrent too? I have not included a shunt sensor (waiting for delivery) so I tried to change the TakeAMPS to return always 0, but that didn't help.
Thanks
Patrick
