/*红外解码的方法 NEC格式 upd6121
1、9Ms的高电平启动头，然后是4.5Ms的低电平，如果2.25Ms时就有高电平，是持续信号，不处理
2、然后以一个高电平和一个低电平为1Bit，高电平时间是0.5625Ms=562us，
高低电平时间比为1:1时是Bit1，比为1:3时是Bit0
3、Timer1中断执行100us采样周期，9Ms＝90，4.5Ms=45，高电平＝5，低电平最多15
4、共读入4Byte共24bit，第1、2Byte是CustomCode码和其反码，第3、4Byte是DataCode和其反码
5、CustomCode正确和DataCode效验正确的话，执行
6、红外接收器输出是反相的-/* IR decoding methods NEC format upd61211, 9Ms start of the high head, and then the low 4.5ms, if 2.25Ms when there is high, is a continuous signal, does not handle 2, and then to a high- level and a low level for 1Bit, high time is 0.5625Ms = 562us, high-low ratio of 1:1 when the time is Bit1, ratio of 1:3 is Bit03, Timer1 interrupt the implementation of 100us sampling period, 9Ms = 90,4.5 Ms = 45, high = 5, low-level maximum of 154, were read into 4Byte were 24bit, No. 1,2 Byte is CustomCode code and its anti-code, the first 3,4 Byte is DataCode and its anti-code 5, CustomCode correct and well-tested DataCode correct, the implementation of 6, infrared receiver output is RP s
