Arduino录制电视遥控红外编码程序

趁着过年，把录制电视遥控红外编码的程序调试成功。

使用方法：
1.  首先输入遥控品牌名称
2.  输入每个按键需要记录的条数
3.  每个按键录制完成之后，提示按c/C继续，其它键退出。

代码

String brandName="";
byte maxRecordsPerButton=0;
boolean stop=false;
int currentRecord =0;

byte getNumber()
{
  char * value;

  String s;
  s=getChars();
  value = &s[0];

  return atoi(value);
}

String getChars(void)
{
  char rcv=' ';
  String str;
  while (rcv!='\n')
  {
    if (rcv!=' ')
      str += rcv;
    if (Serial.available()>0)
      rcv=Serial.read();
    else
      rcv=' ';
  } 
  return str; 
}

void setup()
{
  Serial.begin(9600);
  Serial.println("Please connect your datapin of IR Receiver to D2 for UNO, or D19 for MEGA1280");
  Serial.println(" ");
  Serial.print("Please enter the brand name of your remote:");

  brandName=getChars();
  Serial.println(brandName);
  Serial.println("");
  Serial.println("Please enter how many records ");
  Serial.print("would be recorded per button:");
  maxRecordsPerButton = getNumber();
  Serial.println(maxRecordsPerButton,DEC);

  Serial.println("  Ready to Record ...  ");
  currentRecord=0;
}

void loop()
{
  if (!stop)
  {
    while (currentRecord<maxRecordsPerButton)
    {
      if (currentRecord==0)
      {
        String buttonName="";
        Serial.println(" ");
        Serial.print("Please enter button name:");
        buttonName= getChars();
        Serial.println(buttonName);
      }
      /////

      Serial.println(" ");      
      Serial.println("Press the button, please...");
      listenIR();
      printpulses();

      Serial.println(" ");
      /////
      currentRecord ++;
      if (currentRecord==maxRecordsPerButton)
      {
        Serial.println(" ");  
        Serial.println(" ");     
        Serial.println("Press c or C to continue, others to exit...");
        char c;
        c=getChars()[0];
        switch(c)
        {
        case 'c':
        case 'C':
          currentRecord=0;
          break;
        default:
          //stop
          stop=true;
        }
      }
    }
  }
}

void listenIR()
{
  listenForIR();
}

采集部分程序是基于ladyada的代码

#define IRpin_PIN  PIND    
#define IRpin          2// the maximum pulse we'll listen for - 65 milliseconds is a long time
#define MAXPULSE 65000// what our timing resolution should be, larger is better// as its more 'precise' - but too large and you wont get// accurate timing
#define RESOLUTION 20 // What percent we will allow in variation to match the same code
#define FUZZINESS 20// we will store up to 100 pulse pairs (this is -a lot-)
uint16_t pulses[100][2];  // pair is high and low pulse 
uint8_t currentpulse = 0; // index for pulses we're storing

int listenForIR(void)
{
  currentpulse = 0;

  while (1) {
    uint16_t highpulse, lowpulse;  // temporary storage timing
    highpulse = lowpulse = 0; // start out with no pulse length

    //  while (digitalRead(IRpin)) { // this is too slow!
    while (IRpin_PIN & (1 << IRpin)) {
      // pin is still HIGH

      // count off another few microseconds
      highpulse++;
      delayMicroseconds(RESOLUTION);

      // If the pulse is too long, we 'timed out' - either nothing
      // was received or the code is finished, so print what
      // we've grabbed so far, and then reset
      if ((highpulse >= MAXPULSE) && (currentpulse != 0)) {
        return currentpulse;
      }
    }
    // we didn't time out so lets stash the reading
    pulses[currentpulse][0] = highpulse;

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

    // we read one high-low pulse successfully, continue!
    currentpulse++;
  }
}

void printpulses(void) {
  Serial.println("\n\r\n\rReceived: \n\rOFF \tON");
  for (uint8_t i = 0; i < currentpulse; i++) {
    Serial.print(pulses[i][0] * RESOLUTION, DEC);
    Serial.print(" usec, ");
    Serial.print(pulses[i][1] * RESOLUTION, DEC);
    Serial.println(" usec");
  }
  
  // print it in a 'array' format
  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[i][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);
  Serial.print(", 0};");
}

输入的结果如下


Please connect your datapin of IR Receiver to D2 for UNO, or D19 for MEGA1280

Please enter the brand name of your remote:SONY

Please enter how many records
would be recorded per button:3
  Ready to Record ...

Please enter button name:PowerON

Press the button, please...
