The Constant Current Chopping Wave's Micro-Stepping Drive Circuit of the Stepping Motor Based on AT89C52

Putting forward and introducing the plan and its actualized technology of the constant current chopping wave's Micro-Stepping drive circuit controlled by Chip Microprocessor AT89C52 via reasonably selecting the stepping motor's winding Micro-stepping current wave in order to improve the micro-stepping precision of the drive circuit, to reduce its circulation and to increase its reliability.
