台湾普城公司生产的 PT2262 ,PT2272是一对很好的遥控编码、 解码芯片 ,但改变 PT2262 的地址和发射控制端 TE的控

制 ,需要几个开关同时动作 ,给用户带来不便。给出了用廉价单片机 AT89C2051 代替 PT2262 实现功能的方法 ,用软件来处

理开关的动作 ,操作简便易行。-Cape Town in Taiwan produced PT2262, PT2272 remote control is a pair of good encoding, decoding chip, but to change the address of PT2262 and launch control terminal TE control, while the action takes a few switches, causing inconvenience to users. Given instead of using low-cost microcontroller AT89C2051 PT2262 achieve functional way to deal with a software switch operation, the operation simple and easy.
