Error in IR receiver project

Question

I'm trying to receive remote information with an IR receiver and this is my code:

#include <IRremote.h>

int RECV_PIN = 11;
IRrecv irrecv(RECV_PIN);
decode_results results;

void setup() {
  Serial.begin(9600);
  irrecv.enableIRIn(); // Start the receiver
}

void loop() {
  if (irrecv.decode(&results)) {
    Serial.println(results.value, HEX);
    irrecv.resume(); // Receive the next value
  }
  delay(100);
}

I tried to upload this to Arduino and it says:

exit status 1
redefinition of 'int RECV_PIN'

How can I fix this?

Answer 1

Apparently the name RECV_PIN is used somewhere else, presumably in IRRemote.h -- although not in any version of it I can find. Anyway, just change the name of RECV_PIN to something which doesn't conflict.

For example:

int MY_RECV_PIN = 11;
IRrecv irrecv(MY_RECV_PIN);
