I understand the DRV8825 is a DRIVER class device with the 2 wires (step and direction) enabled (and it can control the Enable pin for a 3rd wire) but the DRV8825 has M0, M1, and M2 available to give Full Step, 1/2, 1/4, 1/8, 1/16 and 132 step resolution settings. Does/Can the AccelStepper library take advantage of that or is that something I need to control outside of the library? I've been looking through the code and I don't see anything that would use those pins but I'm not super good a C++ and could be overlooking something.

Thanks for the help.

Hi,

AccelStepper wont set up those configuration pins for you.

Cheers.

Thanks, I'll quit trying to find something that does not exist. Just was unsure and did not want to skip a valuable setting.
