Help with Adafruit Stepper and DC motor HAT

[gearjammer]

Hi,

I've been playing around with two hacked motors from my Mom's roomba and want to control them from my Pi - which is why I bought the Adafruit Stepper + DC motor HAT.

I wrote some code based on the ADAFruit python libs and am able to drive motors individually but not simultaneously! I'm powering the HAT with a 10000mAh 12v Li-ion battery. From other hacks of the roomba - I've figured out they're 12v motors but not sure if they pull more than 1.2A each - really doubt it.

So my big question is - can the HAT drive two motors simultaneously and what am I doing wrong?

Any help is appreciated.

The standard library only knows how to control motors one at a time. The AccelStepper library knows how to run them at the same time: https://github.com/adafruit/AccelStepper
