This all started with a quad mecanum wheel chassis from ebay. I've driven motors on most projects using the L298N modules, but that then means lots of jumper wires. So this time I want to try out an AT8236 module which I could sit as daughter boards on the main PCB.
Although the PCB is complete and I'm sharing code to test drive the motors, I still have more work to do to make this a driven robot or droid.
I decided to use the RP2040 PWM slicers to not only drive the power control signal but also count rotation. That way I don't have 8 hall sensors constantly interrupting the processor. But with only 8 slicers on the RP2040 and 8 Power lines to drive, that is tricky.
I talk through the design on my YouTube channel @DrJonEA.
