解码原理，利用arduino的微秒函数，通过端口中断（上升源，下降源），得到时间，就可以解码波形

void subir_decode(void)
{
volatile static unsigned long timerf,timerf1,timerf2;
volatile static unsigned long wcdata_decode,bkdata;
volatile static u8 wcshift,bit_enable_rx ;
timerf2 = micros() ;

timerf = 0 ;
//digitalWrite(LED_BLUE, !digitalRead(LED_BLUE));
if(timerf2>timerf1)
{
timerf = timerf2-timerf1 ;
}
timerf1 = timerf2 ;
if((timerf>5000)&&(timerf<20000))
{
// digitalWrite(LED_BLUE, !digitalRead(LED_BLUE));
      //Serial.write(timerf/100);
      wcshift = 31 ;
// wcdata_decode = 0x00 ;
}
else
{

         if(timerf<1800)
         {
            wcdata_decode = wcdata_decode&0xfffffffe ;

         }
         else
         {

            wcdata_decode = wcdata_decode|0x00000001 ;
         }
         if(wcshift>0)
         {
         wcshift-- ;
         wcdata_decode = wcdata_decode<<1 ;
         }
         else
         {


            bfirok = 1 ;
            wcirdecode = wcdata_decode ;


            bkdata = wcdata_decode ;

            wcshift = 255 ;

         // Serial.write((wcdata_decode&0x00ff0000)>>16);
         // Serial.write((wcdata_decode&0x0000ff00)>>8);
         // Serial.write((wcdata_decode&0x000000ff));
         }



}
