51单片机的多机串口互连 通信函数，提供缓冲区，通过P2口的输入决定从机号。在STC89C52，AT89S52上通过。-51 Single-chip interconnection of multi-machine serial communications function, providing a buffer, through the input port P2 from the machine its decision. In STC89C52, AT89S52 adopted.

基于89S52单片机的4位led显示程序，采用定时器记数，最大定时为-89S52-based MCU four led display program, using timer counting, Timing for the largest

说明：此程序使用标准PS2键盘输入，LCD1602液晶屏输出显示。此样例仅作测试使用 晶振使用12M或者11.0592M,本键盘使用部分字母和数字测试，其他按键不能使用，用 户可以自行扩展。由于开发板和程序的各种参数，程序中没有使用奇偶校验，不保证没有 误码,校验程序请自行添加。-Description: This program uses the standard PS2 keyboard input, LCD1602 LCD output display. This sample is only used for testing the use of crystal 12M or 11.0592M, this keyboard to use part of letters and numbers tests, other buttons can not be used, users can expand their own. As the development board and procedures for various parameters, the program does not use parity, does not guarantee that there is no error, verification procedures to add your own.
