Design and implementation of serial communication control system based on STC89C52RC
Abstract
This paper is based on STC89C52RC and level translation chip MAX232,under DB9-pin serial cable, the standard of RS232,by the language of C51,design and realize a Communication Control System of Serial Ports.The mode of its serial ports is Full-duplex,the speed of data transmission is quite fast.The system can receive the control command which is sended by PC timely, make information reply and corresponding control operation according to the command.
Tests show that this system works reliable,performs stable,and it holds the characteristics of good portability and Strong scalability, it can be expended accourding with our wishes,so it has broad application space.
