基于AVR单片机的CH451一应用。8个数码管，16个按钮开关。

该源程序是通过对键盘的扫描方式对键盘按键的识别-The source is the keyboard scan mode by the keyboard keys to the identification of

单片机的设计程序，我认为很好的，希望大家喜欢-MCU design process, I think that"s good, hope you like them! !

我做的按摸椅ＲＳ００１的键盘部分的Ｃ５１程序- I do according to trace chair R S 001 keyboards partial C 51 procedures

利用8051单片机实现对1602液晶显示器驱动，实现时钟功能。-8051 to realize the use of liquid crystal display driver 1602, realize the clock function.

飞利浦I2C接口源LPC932

51单片机的at89c51 的资料信息，可以进一步了解其用法-AT89C51 MCU 51 of the information, you can learn more about its usage

红外线遥控器按键检测程序. 通过检测两次下降沿之间的时间差判断接受到的数据位. 已经通过了测试,能够正确区分出32bit数据的遥控器按键键值. 具有数据重发功能,但是数据的重发有点频繁. 使用晶震频率为11.0592MHz,所有定时值都是基于这个频率计算. 占用很少量的CPU时间,使用了外部中断0接受数据,定时器0进行计数, 定时器1作为串口的波特率发生器(Band = 9600).-Infra-red remote control button detection program. By detecting falling edge twice to determine the time difference between the received data bit. Has passed the test, could correctly distinguish 32bit data button remote control key. With data re-issued, but data a bit of re-issued frequent. Zhenyuan frequency of use of crystal 11.0592MHz, all timing values are calculated based on this frequency. occupied by small quantities of CPU time, use the external interrupt 0 to accept data, timer 0 to count, timer 1 as a string port baud rate generator (Band = 9600).

用8253-8255编写的定时响铃程序 可以定时两个时间点，很经典的程序-spent 8253-8255 prepared by the regular beep procedures regular two points in time, classic procedures

一个很不错的按键单片机C程序-a very good button SCM C Program
