I don't really understand how these two functionalities differ. One is measuring on both low side and high side, the other one only on low side.

The available threshold values are the same in both cases.

When would you use OCD_TH and not STALL_TH, and vice versa?

I also find that the granularity of the thresholds is way too coarse. Below my limit and the motor doesn't move, one step up and it crashes hard into obstacles. Is there any way to get a finer threshold?
