8x8 matrix code help........................Please

Working on some code for my 8x8 matrix.....but it doesn't want to work, think I'm missing the instructions for how long to display each letter?

(oh and how would I make it scroll? :))

#include "LedControl.h"

LedControl lc=LedControl(12,11,10,1);

unsigned long delaytime=100;

void setup() {




void writeMatrix() {

  byte a[5]={B01111110,B10001000,B10001000,B10001000,B01111110};
  byte r[5]={B00111110,B00010000,B00100000,B00100000,B00010000};
  byte d[5]={B00011100,B00100010,B00100010,B00010010,B11111110};
  byte u[5]={B00111100,B00000010,B00000010,B00000100,B00111110};
  byte i[5]={B00000000,B00100010,B10111110,B00000010,B00000000};
  byte n[5]={B00111110,B00010000,B00100000,B00100000,B00011110};
  byte o[5]={B00011100,B00100010,B00100010,B00100010,B00011100};

void loop() { 

at some point you are going to want to call setRow, setColumn, or setChar to move the data from your variable to the actual chips/leds

Thank you Spinlock! got it sorted now :)

Are there any collections of matrix font per coded?

There's a good link about open source pre coded fonts over at http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1244856600/0
