oh sry im using a 32 X 32 RGB led Matrix made by adafruit. and the librarys are #include <Adafruit_GFX.h> // Core graphics library

#include <RGBmatrixPanel.h>

also here is a little bit of my code if it helps:

#define CLK 8

#define OE 9

#define LAT 10

#define A A0

#define B A1

#define C A2

#define D A3

RGBmatrixPanel matrix(A, B, C, D, CLK, LAT, OE, false);

void setup(){

matrix.begin();

}

void loop() {

//matrix.fillRect(0, 0, 32, 32, matrix.Color333(0, 7, 7));

matrix.drawLine(0, 0, 31, 0, matrix.Color333(7, 7, 7));

matrix.drawLine(0, 1, 31, 1, matrix.Color333(7, 7, 7));

matrix.drawLine(0, 2, 14, 2, matrix.Color333(7, 7, 7));

matrix.drawLine(18, 2, 31, 2, matrix.Color333(7, 7, 7));

}
