Hi

1. The first character printed, repeats endlessly.
   It is too big ?
   Some variable does not count so much?

Not Compile.

I copied on the scetch:
Adafruit_mfGFX.cpp
Adafruit_mfGFX.h
fonts.cpp
fonts.h

Removed //#include "application.h"
Added #include <stdint.h>

#include <MCUFRIEND_kbv.h>
#define LCD_CS A3 // Chip Select goes to Analog 3
#define LCD_CD A2 // Command/Data goes to Analog 2
#define LCD_WR A1 // LCD Write goes to Analog 1
#define LCD_RD A0 // LCD Read goes to Analog 0
#define LCD_RESET A4 // Can alternately just connect to Arduino's reset pin
#define BLACK 0x0000
#define BLUE 0x001F
#define RED 0xF800
#define GREEN 0x07E0
#define CYAN 0x07FF
#define MAGENTA 0xF81F
#define YELLOW 0xFFE0
#define WHITE 0xFFFF
MCUFRIEND_kbv tft; // Shield has hard-wired pins
void setup() {
tft.reset();
uint16_t identifier = tft.readID();
tft.begin(identifier);
}
void loop() {}

I tried using this with the Neo Pixeks and neo matrix libraries, Its giving me errors about syncing with the other two libraries.

So, this looks like a nice tool. Trying to include it in a sketch for driving an LED matrix. On my initial effort, the installation complains of a lack of "application.h"

Really not sure how I am supposed to use this. Any clues?

Here are my includes:

include <Adafruit_GFX.h> // Core graphics library

include <RGBmatrixPanel.h> // Hardware-specific library

include<Adafruit_mfGFX.h>
