我正在退出狀態1為板Arduino / Genuino Uno編譯時出錯。嘗試執行基本的IR項目

Question

這是我要在Arduino上運行的代碼。

#include "IRremote.h"

int receiver = 11; // Signal Pin of IR receiver to Arduino Digital Pin 11

/*-----( Declare objects )-----*/
IRrecv irrecv(receiver);     // create instance of 'irrecv'
decode_results results;      // create instance of 'decode_results'

void setup()   /*----( SETUP: RUNS ONCE )----*/
{
  Serial.begin(9600);
  Serial.println("IR Receiver Button Decode"); 
  irrecv.enableIRIn(); // Start the receiver

}/*--(end setup )---*/


void loop()   /*----( LOOP: RUNS CONSTANTLY )----*/
{
  if (irrecv.decode(&results)) // have we received an IR signal?

  {
    translateIR(); 
    irrecv.resume(); // receive the next value
  }  
   }/* --(end main loop )-- */

/*-----( Function )-----*/
void translateIR() // takes action based on IR code received

// describing Remote IR codes 

{

  switch(results.value)

  {

  case 0xFF629D: Serial.println(" FORWARD"); break;
  case 0xFF22DD: Serial.println(" LEFT");    break;
  case 0xFF02FD: Serial.println(" -OK-");    break;
  case 0xFFC23D: Serial.println(" RIGHT");   break;
  case 0xFFA857: Serial.println(" REVERSE"); break;
  case 0xFF6897: Serial.println(" 1");    break;
  case 0xFF9867: Serial.println(" 2");    break;
  case 0xFFB04F: Serial.println(" 3");    break;
  case 0xFF30CF: Serial.println(" 4");    break;
  case 0xFF18E7: Serial.println(" 5");    break;
  case 0xFF7A85: Serial.println(" 6");    break;
  case 0xFF10EF: Serial.println(" 7");    break;
  case 0xFF38C7: Serial.println(" 8");    break;
  case 0xFF5AA5: Serial.println(" 9");    break;
  case 0xFF42BD: Serial.println(" *");    break;
  case 0xFF4AB5: Serial.println(" 0");    break;
  case 0xFF52AD: Serial.println(" #");    break;
  case 0xFFFFFFFF: Serial.println(" REPEAT");break;  

  default: 
    Serial.println(" other button   ");

  }// End Case

  delay(500); // Do not get immediate repeat


}

這是我的錯誤信息。 （我想我固定了第一個。）

Arduino: 1.8.0 (Windows 8.1), Board: "Arduino/Genuino Uno"

Answer 1

該錯誤是不言自明的：“為'IRremote.h'找到了多個庫”

看起來您在兩個位置都具有相同的庫文件。 刪除一個，編譯器就會知道要使用哪個。
