How do I set the stepper micro-steps?

[UnexpectedMaker]

Seems like a silly question, but I see _uStepCount = 256 and no methods to change it?

I want to set my stepper to 8 microsteps, not 256.

All position calculations are done against _uStepCount.

Was this an oversight? or am I missing something?

Thanks :)

Hello,

I haven't looked a lot into it but it seems that 256 microsteps is the standard way of using this driver. As it has an internal motion controller there aren't really any drawbacks to having 256 usteps, AFAIK it emulates a sine wave which makes the motor behave more like a permanent magnet synchronous motor.

You can have a look at the CHOPCONF register if you really want a lower microstep setting. And feel free to submit a PR if it doesn't break anything else ;)
