I have found a program who works on my display, if it can help you ..
#include <Adafruit_GFX.h> // Core graphics library
#include <RGBmatrixPanel.h> // Hardware-specific library
// Similar to F(), but for PROGMEM string pointers rather than literals
#define F2(progmem_ptr) (const __FlashStringHelper *)progmem_ptr
#define CLK 8 // MUST be on PORTB! (Use pin 11 on Mega)
#define LAT A3
#define OE 9
#define A A0
#define B A1
#define C A2
// Last parameter = 'true' enables double-buffering, for flicker-free,
// buttery smooth animation. Note that NOTHING WILL SHOW ON THE DISPLAY
// until the first call to swapBuffers(). This is normal.
RGBmatrixPanel matrix(A, B, C, CLK, LAT, OE, true);
// Double-buffered mode consumes nearly all the RAM available on the
// Arduino Uno -- only a handful of free bytes remain. Even the
// following string needs to go in PROGMEM:
const char str[] PROGMEM = "Adafruit 16x32 RGB LED Matrix";
int textX = matrix.width(),
textMin = sizeof(str) * -12,
hue = 0;
int8_t ball[3][4] = {
{ 3, 0, 1, 1 }, // Initial X,Y pos & velocity for 3 bouncy balls
{ 17, 15, 1, -1 },
{ 27, 4, -1, 1 }
};
static const uint16_t PROGMEM ballcolor[3] = {
0x0080, // Green=1
0x0002, // Blue=1
0x1000 // Red=1
};
void setup() {
matrix.begin();
matrix.setTextWrap(false); // Allow text to run off right edge
matrix.setTextSize(2);
}
void loop() {
byte i;
// Clear background
matrix.fillScreen(0);
// Bounce three balls around
for(i=0; i<3; i++) {
// Draw 'ball'
matrix.fillCircle(ball[0], ball[1], 5, pgm_read_word(&ballcolor*));
_ // Update X, Y position*
ball[0] += ball*[2];
ball[1] += ball[3];
// Bounce off edges*
if((ball[0] == 0) || (ball*[0] == (matrix.width() - 1)))
ball[2] = -1;
if((ball[1] == 0) || (ball[1] == (matrix.height() - 1)))
ball[3] = -1;
}
// Draw big scrolly text on top*
* matrix.setTextColor(matrix.ColorHSV(hue, 255, 255, true));
matrix.setCursor(textX, 1);
matrix.print(F2(str));
// Move text left (w/wrap), increase hue*
* if((--textX) < textMin) textX = matrix.width();
hue += 7;
if(hue >= 1536) hue -= 1536;
// Update display*
* matrix.swapBuffers(false);
