Universal Motor Driver DC Brush Motor demo code

McGyver

The online guide shows this drive can be used with DC Brushed motors yet doesn't point to any demo software for a start. Current demo and advanced code is for BLDC motors. Also, there is a difference in REV A & B. however I don't know if it matters for code. I have 2 Power chair motors I would like to use with it.

They are 24 VDC and preliminary amps testing went from 3 no load and 6 with hand friction on shaft. I am also wondering if this can be controlled by another MCU like BS2 or P1. I am looking at the hardware that is on the BOM for both REV thinking I need some PWM Robot code to try. Any questions and suggestions would be nice.

Guy over on the LinuxCNC forum uses these
on his CNC mill retrofit and he's really happy with them.

Was sure that I ordered some but apparently not.

My apologies for not being clearer,again. I was referring to Parallax product SKU 64010. https://www.parallax.com/product/universal-motor-driver-p2-add-on-board/ I do have a couple of those exact drives I used on an Arduino project. They sure came down in price.
Now, to myself, "where would that software be"?

Hi,
perhaps it would be a good idea to use a very small motor first to do some experiments. Use the rated voltage for that motor as supply voltage. Switch the low side of the H-bridge on permanently. Then switch on and off the high side. After that works use a PWM signal to the high side.
Good luck!
