'irrecv' does not name a type

[Helghallen]

Hi:

I have searched and tried the various reinstalling libraries and such to no avail. I have code that will use irrecv.enableIRIn(); // Start the receiver with no issues, but in my new sketch it gives me the above error and I am not sure why.

My code is:
#include <boarddefs.h>
#include <IRremote.h>
#include <IRremoteInt.h>
#include <ir_Lego_PF_BitStreamEncoder.h>





#include <Adafruit_NeoPixel.h>

int IRpin = 02;  // pin for the IR sensor
IRrecv irrecv(IRpin);
decode_results results;
#define PIN 1


#ifdef __AVR__
  #include <avr/power.h>
  #endif
boolean LEDon = true; // initializing LEDon as true

Adafruit_NeoPixel strip = Adafruit_NeoPixel(36
, PIN, NEO_GRB + NEO_KHZ800);
void setup()
{
  strip.begin();
  strip.show(); // Initialize all pixels to 'off'
}
    irrecv.enableIRIn(); // Start the receiver

}

void loop()
{
       uint32_t gold = strip.Color(255, 255, 0);
         uint32_t blue = strip.Color(0, 0, 255);
         uint32_t green = strip.Color(0, 255, 0);
   
  if (irrecv.decode(&results))
    {
     
      irrecv.resume();   // Receive the next value
    }
 
  switch(results.value)
 {

  case 16738455:
  for( int i = 0; i<36; i++){
        strip.setPixelColor(i, blue);
        strip.show();
    }    // Solid Blue
  break;
 
  case 16724175:
   for( int i = 0; i<36; i++){
        strip.setPixelColor(i, green);
        strip.show();
    }   // Solid Green
  break;
 
  case 16718055:
  for( int i = 0; i<36; i++){
        strip.setPixelColor(i, gold);
        strip.show();
    }   // Solid Gold
  break;
 
 
 
  }
 
}


My goal is to make a neopixel ring turn to various colors and styles with the IR remote but this code won't compile and I am not sure why.

Thanks for any help

Look where your setup function ends.

That means that this

Code: [Select]

irrecv.enableIRIn(); // Start the receiver
is not in a function.
C++ doesn't like that.

[INTP]

Yep.

Also, my sketches have wire.h included for some reason.

I am not sure what you mean by that. I looked at the other sketch where this works and I don't see a difference?

#include <IRremote.h>

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

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

void loop()
{
  if (irrecv.decode(&results))
    {
      Serial.println(results.value, DEC); // Print the Serial 'results.value'
      irrecv.resume();   // Receive the next value
    }
 
 
}

Your setup:

Code: [Select]

void setup()
{
  strip.begin();
  strip.show(); // Initialize all pixels to 'off'
}



That setup:

Code: [Select]

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

Holy cow. That worked. I am so new to all this. But I understand now what I was doing wrong. I just moved the problem line into the same bracket thing as the strip commands.

thank you so much.

but now in trying to upload to my Gemma, it says the sketch is too big. I am too new at this that I am not sure what is making it that big?

[INTP]

Let's make sure you understand this, and it does bear belaboring.

Code: [Select]



void setup()
{

//setup stuff goes here

}




//you put stuff here


void loop()
{

//looping stuff goes here

}





And your code is large because of the included libraries.

[Helghallen]

Yes it does. Learning as I go and sometimes the old noggin doesn't quite put two and two together and get 4.
