I have been playing with the 8x8 led matrixs and have had good success using the arduino pins. I now want to move on and use a MAX7219 LED Matrix Controller. I ran the code below and got errors, and am now stuck.
The code is an example and the same code that I have found when googling... So if you could help that would be great to get me started.
#include <Sprite.h>
#include <Matrix.h>
// Hello Matrix
// by Nicholas Zambetti <http://www.zambetti.com>
// Demonstrates the use of the Matrix library
// For MAX7219 LED Matrix Controllers
// Blinks welcoming face on screen
// Created 13 February 2006
/* create a new Matrix instance
pin 0: data (din)
pin 1: load (load)
pin 2: clock (clk)
*/
Matrix myMatrix = Matrix(0, 2, 1);
void setup()
{
}
void loop()
{
myMatrix.clear(); // clear display
delay(1000);
// turn some pixels on
myMatrix.write(1, 5, HIGH);
myMatrix.write(2, 2, HIGH);
myMatrix.write(2, 6, HIGH);
myMatrix.write(3, 6, HIGH);
myMatrix.write(4, 6, HIGH);
myMatrix.write(5, 2, HIGH);
myMatrix.write(5, 6, HIGH);
myMatrix.write(6, 5, HIGH);
delay(1000);
}
