PC机与AT89C51单片机的串行通信系统设计
he communication system design of PC machine with AT89C51
本文介绍了应用AT89C51单片机与PC机进行串行通信的软、硬件设计方法和实现过程。PC机将需要传输的数据通过串行口传送给单片机，单片机接收并在LCD上显示接收的数据。系统采用MAX232芯片实现RS232的EIA电平与单片机TTL电平的转换，并采用1602液晶显示。
his article describes the hardware and software design of serial communication system between PC machine and AT89C51。The AT89C51 recives the datas that transmited by the pc and shows them on the LCD.the system translators the ETA to TTL using MAX232,then shows the datas on the LCD of 1602.
