LED Matrix

I have made a LED matrix. It's made with 796 red LEDs. The panel is controled by a microchip PIC18F2580.

It can display up to 84 characters (in scrolling mode). In fix mode, it can display 16 characters. Blinking and reverse mode are also available.

I have drawn the electronic board with PROTEUS.

The project is made with two kind of cards and 7 cards at all.

The first one can be called "control card", is the one with the microcontroller, power supplies.

The last six cards are the same and can be called LEDs cards.

I choose to use a microchip PIC18F2580 (I ordered some samples directly on microchip website).

I programmed with MPLAB X IDE with XC8 compiler.
