My prototype is finished and I start working on the code today. I'm also
using uclibc and kernel 2.6 with fli4l.

Yes cool work! I would have ordered such a PCB if there is a possibility
not to upload the firmware by myself. I do not want to order or solder a=20
programmer for this one-time job. Or are there changes in the firmware
expected?

@Till - is it possible to order both a PCB and an already programmed
Atmega? If so, please tell me the details (price, bank account ...) and i
will transfer the money asap to you.

Fine! You are driving the PCB and the LCD from USB? Or do you have a
seperate voltage feed?

For my GPIO experiments I ordered some MAX619/MAX1682/MAX1683.

I don't tink so.
1st - programming the Atmel is a problem for anybody out there who hasn't
to do anything with Atmels before.
2nd - using GPIO on WRAP enables the possibility to put the LCD in the
WRAP enclosure. O.K. not into the original one - but my enclosure has
enough room on the front to put a 16x2 LCD in.
3rd - my programming skills arn't as good as they should be. It's a good=20
project to increase them.
4th - there is our own fli4l-lcd package (much older than lcd4linux I
think). I think that implementing GPIO into that tiny thing is much easie=
r
for me than starting to do that with lcd4linux.

So please let me try.
