Hi everyone,
I am experimenting an MC33926 motor driver shield for Arduino from https://www.pololu.com/product/2503.
I did the soldering for all pins and connect it to an Arduino Uno R3. I am following the demo instructions https://github.com/pololu/dual-mc33926-motor-shield/tree/master/examples/Demo.
I uploaded the code and serial immediately said “fault” when I turn on the power supply for the pololu board. I use a power supply of 12V and 2.5A current limit. However, despite the serial “fault”, the motor still runs in one direction and stop when it reaches full range. This “fault” appears even though I tried disconnecting the motor from the pololu board. So I guess some problem may appear between arduino uno and mc33926.
I use a P16-P motor from actuonix. https://s3.amazonaws.com/actuonix/Actuonix+P16+Datasheet.pdf. It has stall current of 1A so I think 2.5A from power supply is enough.
Thank you for your help
