代码如下：

#define IRpin_PIN      PIND
#define IRpin          2

#define MAXPULSE 65000

#define RESOLUTION 20

uint16_t pulses[100][2];  // pair is high and low pulse
uint8_t currentpulse = 0; // index for pulses we're storing

void setup(void) {
  Serial.begin(9600);
  Serial.println("Ready to decode IR!");
}

void loop(void) {
  uint16_t highpulse, lowpulse;  // temporary storage timing
  highpulse = lowpulse = 0; // start out with no pulse length
 
    while (IRpin_PIN & (1 << IRpin)) {
     highpulse++;
     delayMicroseconds(RESOLUTION);

     if ((highpulse >= MAXPULSE) && (currentpulse != 0)) {
       printpulses();
       currentpulse=0;
       return;
     }
  }
  pulses[currentpulse][0] = highpulse;
 
  while (! (IRpin_PIN & _BV(IRpin))) {
     // pin is still LOW
     lowpulse++;
     delayMicroseconds(RESOLUTION);
     if ((lowpulse >= MAXPULSE)  && (currentpulse != 0)) {
       printpulses();
       currentpulse=0;
       return;
     }
  }
  pulses[currentpulse][1] = lowpulse;

  currentpulse++;
}

void printpulses(void) {
  Serial.println("\n\r\n\rReceived: \n\rOFF \tON");
  for (uint8_t i = 0; i < currentpulse; i++) {
    Serial.print(pulses[0] * RESOLUTION, DEC);
    Serial.print(" usec, ");
    Serial.print(pulses[1] * RESOLUTION, DEC);
    Serial.println(" usec");
  }
 
  Serial.println("int IRsignal[] = {");
  Serial.println("// ON, OFF (in 10's of microseconds)");
  for (uint8_t i = 0; i < currentpulse-1; i++) {
    Serial.print("\t"); // tab
    Serial.print(pulses[1] * RESOLUTION / 10, DEC);
    Serial.print(", ");
    Serial.print(pulses[i+1][0] * RESOLUTION / 10, DEC);
    Serial.println(",");
  }
  Serial.print("\t"); // tab
  Serial.print(pulses[currentpulse-1][1] * RESOLUTION / 10, DEC);
