Hi, So i've recently acquired https://www.sparkfun.com/products/759
, an LED Matrix + backpack and I've looked over the schematics and tried to build a project with it with its sample code given (http://www.sparkfun.com/datasheets/Components/LED_MATRIX_CODE.zip
) with an Arduino Duemilanove.
An experienced arduino user helped me with the wiring connections with male to male molex connectors but after all the appropriate connections were made, the LEDs only flashed its 'startup animation' which is 3 lines of colours scrolling 3 times.
We tried other code (http://tokage.cafe24.com/ww/2008/01/led_backpack.html
) and nothing changed.
We tried another arduino board (MEGA) and nothing changed about it.
We tried new wires and nothing changed about it.
So after a few hours of searching for tips on how to use the backpack provided by Sparkfun, we decided to turn to forums to see if anybody else has had any experience with this particular product and if they could be kind enough to give some sort of advice about it!
Essentially, I'm making a LED 8x8x3 interface that counts up by integers of 14 ticking multiple times per hour. The code starts/stops upon holding a button.
Thanks in advance!
