Compiler Error - 'Color' was not declared in this scope

Projects Programming

I'm getting the error 'Color' was not declared in this scope on the code below with c = Color(255,0,0); being highlighted. I'm trying to get the LPD8806 LED strips to run a color pattern from the center and I'm missing something that's preventing the code to compile.

Thanks,
Phil

    #include "LPD8806.h"
    #include "SPI.h"

    int dataPin = 2;   
    int clockPin = 3;
    const int numPixels = 32;

    LPD8806 strip = LPD8806(32, dataPin, clockPin);

    void loop() {
          int i;
          uint32_t c;

          // Set all pixels to red
          c = Color(255,0,0);
          for (i=0; i < strip.numPixels(); i++) {
              strip.setPixelColor(i, c);
          }
          strip.show();
          delay(100);

     
          // Wipe from middle:
          c = Color(255, 255, 255); // white
          for (i=strip.numPixels() / 2 - 1; i >= 0; i--) { // half of strip, count down to 0
            strip.setPixelColor(i, c); // left pixel
            strip.setPixelColor(strip.numPixels() - 1 - i, c); // right pixel
            strip.show();
            delay(100);
          }
    }

Uh-oh... where is the setup? Even if you don't use the setup, you must do this:

void setup(){
}

Oh right, on the line of c = Color(255,0,0); you need to do this instead:

c = strip.Color(255,0,0);

Looks like Color is a member function of the object created. Just as you did with all the other member functions, you need to tell the compiler which object to call that function for.

And it works...thanks for the quick help!

And the setup must be before the loop.

Most assuredly, not the case. Try it with the most trivial example.

Huh?

Huh?

The order of the standard function definitions does not matter:

void loop() {
   // Do nothing
}

void setup() {
  // WAT?
}

This code works fine.

color wipe was not declared in this sicope

Yo, migueluzbel ... it's a good idea to check the date of any post before replying. (This one was 5 and a half years ago..)

Don't worry tho - it happens.
