一个液晶显示器TX240128程序。我把我小孩的相片做在上面了，如果你用51的片子就能调试你的显示器了。端口连接在程序中有定义。你看下就知道了哈！-A liquid crystal display TX240128 procedures. I put my kids to do in the photo above, if you use the 51 films will be able to debug your display has. Port in the procedure definition. You know facie Ha!

单片机控制键盘和led，键盘送入的数据在led 上显示，数据满四位后，键入的第5位数据在个位显示，前四位清零。-MCU control the keyboard and led, keyboard into the data led the show, data-4, Type the first five places in the data revealed that four former reset.

这是一个简单的红外解码程序，是针对9ms起始码和4.5ms结束码的红外信号。晶振用的是11.0592M的，经测试能用。-This is a simple infrared decoding procedure is 9ms start code and end code 4.5ms infrared signal. 11.0592M crystal is used, and can be tested.

在现代电子系统中，有为数众多的IC需要进行相互之间以及与外界的通信。为了提供硬件 的效率和简化电路的设计，PHILIPS开发了一种用于内部IC控制的简单的双向两线串行总线I2C-In modern electronic systems, there are a large number of IC need each other and communicate with the outside world. In order to provide the efficiency and simplify the hardware circuit design, PHILIPS developed an IC for internal control, a simple bi-directional two-wire serial bus I2C.
