I'm trying the library with your eBay matrix module, i have simplifyed the code for only drawing an expanding / contracting rectangle

#include <avr/io.h>
#include "LedMatrix.h"

LedMatrix  				ledDisplay	= LedMatrix(51, 53, 52, 16, 16);

void setup()
{
  ledDisplay.init(8);
  ledDisplay.blank();
  ledDisplay.update();
  Serial.begin(9600);
}

void loop()
{
  for (int i=0;i<16;i++) {
   ledDisplay.rectangle(0,0,i,6,1);
   ledDisplay.update();
   Serial.println(i);
   delay(50);
  }
  for (int i=16;i>0;i--) {
   ledDisplay.rectangle(0,0,i,6,0);
   ledDisplay.update();
   Serial.println(i);
   delay(50);
  }
  ledDisplay.blank();
  ledDisplay.update();
}

I have only 2 modules cascaded,

when matrix is defined 16x16 it work

LedMatrix(51, 53, 52, 16, 16);

when matrix is defined 16x8

LedMatrix(51, 53, 52, 16, 8);

all the two matrix show the same thing and

when matrix is defined 8x16

LedMatrix(51, 53, 52, 8, 16);

only one matrix module (on the left) work.

Probably you not intend develop the library for use it rectangular matrix, but if a day you want make the work... :slight_smile:
