电脑音源切换控制器（带红外功能） 用AT89C251+CD4016切换控制，可控制四路以上的立体音源输入切换，一路立体声输出,有红外遥控PC功能。

在单片机应用设计中，4*4键盘是经常用到的，在这个程序种，提供了驱动键盘的基本函数，用户可以直接调用，可以很容易的移植到你的系统上。程序中并附带了，lcd1602的驱动程序-Application in the design of single-chip, 4* 4 keyboard is frequently used in the process of providing the basic function-driven keyboard, users can directly call, can be easily ported to your system. And incidental to the proceedings, lcd1602 driver

126*64或192*64LCD驱动程序包，控制芯片HD61202-126* 64 or 192* 64LCD driver package, control chip HD61202

蜂鸣器响 改变蜂鸣器的频率，通过改变延时时间 蜂鸣器的时间要是是靠延时来完成的-Buzzer buzzer ring to change the frequency by changing the delay time if the buzzer is the time to be completed by the time delay

用8051单片机 DS18B20显示是用LED,单片机用AT89S52. 做的温度控制系统-With the 8051 DS18B20 display is used LED, Microcontroller with AT89S52. To do temperature control system

计时器，５１源码，芯片是７7E58,精度是10uS，上升沿，下降沿，脉宽都可以测量，８路同时测量，１０个数据存储，指标就这样了-Timer, 51 source code, chip is 77E58, precision is 10uS, rising edge, falling edge, pulse width can be measured, 8-channel simultaneous measurement, 10 data storage, so the indicators
