LEDMatrix: field 'm_OutOfBounds' has incomplete type 'CRGB'

[JaredTamana]

Hi there. I'm trying to use LEDText on a WS2812B 32x8 controlled by a Nano 328P. When I try to include LEDText, I get an error regarding LEDMatrix's header file and the struct definitions of CRGB:

                 from D:\OneDrive\Documents\Arduino\sketch_may22a\ledtext\ledtext.ino:1:

LEDMatrix.h:27:17: error: field 'm_OutOfBounds' has incomplete type 'CRGB'

     struct CRGB *m_LED;

I'm not sure if this is a library issue or something I've done, but this occurs even when I've only written the bare minimum setup.

#include <Font12x16.h>

#include "config.h"

cLEDMatrix<-MATRIX_TILE_WIDTH, -MATRIX_TILE_HEIGHT, HORIZONTAL_ZIGZAG_MATRIX,
    MATRIX_TILE_H, MATRIX_TILE_V, HORIZONTAL_BLOCKS> ledmatrix;
CRGB *leds = ledmatrix[0];

// a bunch of definitions for FastLED code

void setup() {
  FastLED.addLeds<WS2812B, LED_PIN, COLOR_ORDER>(ledmatrix[0], ledmatrix.Size());
  FastLED.setBrightness(2);
  cLEDText ScrollingMsg;
}

void loop() {

  // a bunch of commented FastLED code

}

void drawPattern(uint16_t patternArray[], int patternSize, long int colour) {
  uint16_t nextPixel;
  int pixelCounter = 0;
  for (int i = 0; i < NUM_LEDS; i++) {
    for (int j = 0; j < patternSize; j++) {
      nextPixel = pgm_read_word(&patternArray[pixelCounter]);
      if (i == nextPixel) {
        ledmatrix.DrawPixel(floor(i / 8), (i % 8), colour);
        pixelCounter++;
      }
    }
  }
}

void singleLED(int number, int delaytime, long int colour) {
  ledmatrix.DrawPixel(floor(number / 8), (number % 8), colour);
  FastLED.show();
  delay(delaytime);
}

What're my next steps? Where am I tripping up?

Only had a quick look but noticed that you include the FastLED header after the LEDMatrix header, this will cause problems as the CRGB structure is only declared in FastLED :) Try this order:-

include

That'll do it! Thanks, I'm just getting back into Arduino, it's been a while :)
