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.

自制的数字电压表，用的的是AD0809这个芯片，希望能有用对大家。-Self-made digital voltage meter, is used in the AD0809 chip, hoping to be useful for everyone.

这个SP2358外扩串口芯片的C语言源程序。非好好用。-Extend outside the SP2358 chip serial C language source code. Non-properly used.

本程序是用于通用同步和异步串行接收器和转发器（ＵＳＡＲＴ），使用中断方式异步接收和发送数据通信源的程序文件。-this procedure is common for serial synchronous and asynchronous receiver and transponder (USARTs), the use of asynchronous interrupt receive and transmit data communication source program files.

液晶显示的完整程序，是你能很好的借鉴lcd的编程思想。-LCD complete procedures, is that you can draw very good lcd programming ideas.
