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>

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

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() {}
