may I ask you for a circuit-schematic?

Sure. I know that I have to do it. 3 weeks ago I started to write a wrapd
witch is able to light the WRAP-LEDs and reacts on pressing the
WRAP-push-button. Bevore that, I havn't written any line of c-code for 10
or 15 years.

It was pretty hard to learn that stuff again ... but now it's included
into fli4l as wrap-addon. If you like, get the source from the .zip here:

Yes, i totally agree.

I'll see, what I get during programming ... I hope, my coworkers at fli4l
will help me on that.

Do you know how many milliamps are allowed to get out of the GPIO-header?

Meanwhile, I started a wiki-page at
http://wiki.port23.de/index.php?title=3DLC-Display_f%C3%BCr_das_WRAP

I collect all the stuff here.
