Abstract
This paper explains how to use the two step motors with driving chip ULN2803 and A3967SLB to control two step motors with different precisions. In order to achieve reverse rotation and forward rotation, A3967SLB controls its ports DIR, MSI, STEP based on its logic timing. On the other hand, ULN2803 controls stepper motor according to the excitation table. Both of the two different control methods can control the horizontal direction, and the vertical direction. In this way, we can make a general system based on 15 Single Chip Micro-computer.关键词
