Re: String input from serial input instead of static progmem?

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

Panel8x8 Library has been tested with 10 panels.

"; void setup(){panel.Begin(buffer,512,strlen(buffer),0);} void loop(){pa...

Re: String input from serial input instead of static progmem?

Yup, You're right Paul, I covered this in example 6 of my library. http://code.google.com/p/panel8x8/wiki/Panel8x8Control 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 progr...

Re: Panel 8x8 Support 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 later ...

Re: Panel 8x8 Support 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 download...

Re: LED's in your video

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 g...

Re: Game of Life?

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! ;-)
