说明：  遥控器使用方便，功能多．目前已广泛应用在电视机、VCD、DVD、空调等各种家用电器中，且价格便宜，市场上非常容易买到。如果能将遥控器上许多的按键解码出来．用作单片机系统的输入．则解决了常规矩阵键盘线路板过大、布线复杂、占用I／O口过多的弊病。而且通过使用遥控器，操作时可实现人与设备的分离，从而更加方便使用。下面以TC9012编码芯片的遥控器为例。谈谈如何用常用的51系统单片机进行遥控的解码。
(Remote easy to use, features and more. Has been widely used in TV, VCD, DVD, air conditioning and other household appliances, and the price cheap, the market is very readily available. If you can remote control many of the key decoder out. Single-chip microcomputer system used for input. The solution of conventional keyboard matrix circuit board is too large, complex wiring, occupied by I/O port too many ills. But also through the use of remote control operation can realize the separation of people and equipment, thus more convenient to use. The following code to TC9012 chip remote control as an example. To talk about how to use the 51 commonly used system for remote control single-chip decoder.)
