Hi every one, has anyone tried to drive a stepper motor from a old 5.25" floppy disk drive? The reason why I chose this was because it has a stepper motor already wired up to the driver IC, which is LB1656M. Trouble is the data sheet for the IC from Sanyo hasn't got enough information. All I got is the timing diagram. I can only make the IC to drive the motor continuously or not rotating at all. I can't stop the motor once it's in motion, and I can't make it move to the number of steps I want. Has anyone tried this IC before? Please help.
