LED 8x8 Matrix via shift registers

Matrix8 Library

LED 8x8 Matrix via shift registers.

This library control LED 8x8 matrix via two shift registers (for example 74HC595).

How to use

• Download all repo files
• Go to arduino IDE root
• Copy all files to library/Matrix8
• Just use!

Simple example

Drawing cross

#include "matrix8.h"

// Init matrix8
//   latch - 7
//   clock - 6
//   data  - 8
Matrix8 matrix(7, 6, 8);

void setup() {
  // Creating two diagonal lines (cross)
  for (int i = 0; i < 8; i++) {
    matrix.set(i, i, true);
    matrix.set(i, 7 - i, true);
  }
}

void loop() {
  // Loop draw
  matrix.draw();
}

Functions

• Matrix8(latch, clock, data) - init matrix8 constructor
• set(x, y, value) - set segment value by position
• draw() - draw row by row matrix
• draw(delay) - draw with delay after rows print, just for test
• getBuffer() - return matrix buffer pointer (example/smile-animate)
• clear() - clear matrix buffer
