Abstract:

In this artical, a new method of serial communication using special purpose level conversion chip MAX232 between PC and MCS 51 single chip microcontroller is introduced. The selection of the communication mode, setting of the baud rate of the 89C51 and its setting of communication are stated in detail. Through the analysis of the hardware and software design of the interface circuit, its practicability is presented.
