Take a look at my power distribution scheme (interconnects) for the 8x8 panels at:
http://crjones.com/panel8x8
I got it working with 10 panels!

Also note, and no offense intended,
Paul's Demo Code only works for 2 panels.

Panel8x8 Library has been tested with 10 panels.

From Panel8x8 Wiki:

To make the panels wait for serial data,
Run the following sketch on the arduino:

#include <Panel8x8Serial.h>
Panel8x8Serial panel;
char *buffer[512]=". ";
void setup(){panel.Begin(buffer,512,strlen(buffer),0);}
void loop ...

Yup, You're right Paul,
I covered this in example 6 of my library.

Basically, Panel8x8 control is a text window,
Type in some text, and it appears on the panel.
Since I had this working pretty well,

I decided to code a Twitter Reader,
Same ...

Posted a short video < 4mb on how to use the Animator included in the support library.

Version 1.09 has been posted.
Please get the latest version if you're not up to date.

Would love to have some feedback of what you think of the library.

Whew,
Working the last bug in the library now.

You can now move all of your aminations to SD card,
Hook up an SD card reader to to the arduino,
and stream all those animations to the panel array.
Pretty much gives you unlimited animation capability.

Should be version 1.08 which I'm posting up ...

Rumor confirmed...
It's example 5 of my panel8x8 library....

Great question,

It's really easy to create animations with version 1.06 of the library & Microsoft Windows.
Version 1.06 supports updating the panels over the serial connection,
including Text and Graphics.
I've also included a set of DotNet utilities for creating graphics visually.
You can ...

When I chose LEDs for my build,
I chose something I knew the vendor would be stocking for a while.
As I was sure I'd be making several purchases.
Well, I started with 200, ramped up to 500,
Now I'm ordering by the 1,000.

I chose 697522 from JameCo,
About 9 cents per 100, or 7 cents per 1000.
Had a ...

I've posted a notice over in the 8x8 LED PANEL forum about a new library that I've created in support of the panels.
Check it out!
It's now a breeze to create animations, text, and directly output to the 8x8 Panels.

Code Library can also be found at:

Feedback ...

Remember that library I was teasing about?
Well, it's finally in production.

My first cut of the library is at
http://Code.Google.Com/p/panel8x8

The library comes with 5 examples at the moment:
Text Scrolling from RAM
Test Scrolling from FLASH
Animation from FLASH
Uses the Panels as direct output ...

I hear rumor that there's a new 8x8 library on the way.
Hmmm, sounds like game of life would be a great sample app.
Very evil grin!
