：章介绍了数据采集系统中STC12系列单片机与PC机之间的串行通信。设计了sTc12c2052AD 与
MAX232的硬件电路，使用汇编语言编程，设置了串行1：7的工作方式，相应的波特率计算方法及特点，发送并接
收数据。单片机从EEPROM 中读取数据，通过R．S-232将其传入PC，并将数据存储在24C02中。-: Chapter introduces data acquisition system STC12 Series MCU and PC serial communication between machines. Designed sTc12c2052AD with MAX232 hardware circuit, the use of assembly language programming, set up the way the work of serial 1:7, the corresponding baud rate calculation method and the characteristics of sending and receiving data. Single-chip EEPROM read data from, by R. S-232 to incoming PC, and data storage in the 24C02.
