Hi all,
I want to control 2 stepper motors with my handyboard. I want to do
microstepping for high resolution. I already have a couple of vexta
unipolar(6 wire) steppers. I also have the TI Sn754410 H-bridge chips.
I now understand the need for H-bridges when dealing w/ bipolor
steppers, but can you still use H-bridges when the motors are unipolor?
Is there a need for external diodes? Should I use a ULN2803 instead?
Has anyone written any software for steppers yet?
