Abstract

The invention provides a microcomputer precise positioning control system which comprises an integrated circuit board, a central processing unit, and a processor. The processor is used for processing the differential data outputted by the central processing unit, and the processed data is outputted to a driving circuit. The processor directly communicates with the integrated circuit board through the central processing unit, special communication and decoding chips are not needed, and the cost is saved greatly. After the serial communication port of the processor is used, a more safe and reliable communication function can be provided, and the stable working of the system is facilitated.

Description
