Other Parts Discussed in Thread: TIDA-00641
I am thinking of a design using drv8881P to drive two BDC or one stepper motor (with microstepping function) with one BOM, instead of two BOM, i.e. drv8881P for BDC and drv8881E for stepper motor respectively.
I learned that drv8881p and drv8881e maybe pin to pin compatible from a view of MCU( c2000 will be used in this case), but that way will involve two manufactory BOMs which is not preferred.
So, my questions are
1) will the drv8881P drive a stepper motor well? I am expecting at least 256 micro-stepping capability.
2) if the 1) is yes, what would be the best way to realize the microstepping? DAC on Vref or like the solution in TIDA-00641 ?
any input will be appreciated and please correct me if I totally misunderstand it.
