51系列单片机的软件串口模拟程序代码，可以实现串口扩展功能，经过项目验证可以直接放心使用，用c写成-51 series microcontroller simulation software serial code, can achieve serial expansion function, After certification projects can directly worry about, written with c

用C语言写的红外遥控解码程序，，，， 语法上没错，但解码完成后有错，，没个按键的都一样，，不知道什么问题，望指点，，EMAIL:wjsjdeng@sina.com.cn-C language to write the infrared remote control decoder,, the grammar is correct, but after the completion of decoding wrong, not a button are the same, and do not know what, look a spot, EMAIL : wjsjdeng@sina.com.cn

状态1：正常时，8个LED发光二极管（彩灯）循环点亮。 • 状态2：有报警时，蜂鸣器发出报警声（用P3.3接一个按键，模拟产生报警信号。当开关合上，发生报警；当开关断开，报警停止。用P3.7输出音频信号驱动扬声器，作为报警信号），同时8个LED发光二极管（彩灯）闪烁。 P3.2接一个按键，用于消除报警-Status 1: normal, eight LED light-emitting diodes (lantern) light cycle.
