：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.

本程序是并口FLASH 39sf040读写程序,并给出调用函数.-This procedure is a parallel port to read and write FLASH 39sf040 procedures, and gives call function.

1.通过键盘、LCD来进行超低功耗实验 2 在一段时间内，如果用户没有进行按键操作，系统将进入“睡眠”－－低功耗状态 3 用户按键后，系统从低功耗状态转到正常的工作状态 4 在非低功耗状态下，程序接收键盘按键执行加法器操作(因为键盘和LCD限制不能实现复杂 5 的功能,如乘法、减法、除法等）.-1. Through the keyboard, LCD for ultra low-power experiment 2 over a period of time, if the user does not have keys to the operation, the system will enter a " sleep" - low-power status 3 users button, the system switch from the low-power state to normal working condition 4 in the non-low-power state, the implementation of procedures to receive the keyboard keys adder operation (because the keyboard and the LCD can not limit the complexity of the functions of 5, such as multiplication, subtraction, division, etc.).
