Hi,
As we are in the OSHW section I am looking for a design (hardware and software) for bipolar stepper motor driver that is based on Atmel AVR or ARM (preferably AVR) and does support micro-stepping.
I am asking for Atmel because currently it is the only MCU that I have mastered the programming tool chain and I have already different MCU versions and programmers for it.
I can design and make the hardware but I am not good enough to program it!!
Micro-stepping is hard and not easy to implement it in a good way!
My general idea would be some MOSFETs with gate driver and MCU with the proper protection.
Hope someone would help
