Jason, can you share these fonts at all. I am
making good progress on integrating LCD support
into my replacement firmware but I only have one
6x8 font set, and it's not complete. I need the
font to be in the vertical byte format that
the NXT display uses.

According to the worst case spec sheet, yes. Under
normal temperature and voltage conditions, like
in my office, it's a much bigger number.
I've reflashed my firmware hundreds of times
with no obvious side-effects.

Yes. I have a complete GCC build system, with
a line oriented interface to GDB through the
USB port.

I would really, really like this newsgroup to be
that one point of entry for this kind of
discussion.
It does a couple of things including:
1. Keeps focus in one place
2. Allows web or email information transfer
3. Is searchable
4. Keeps people coming back to Lugnet
Question for Lugnet admins...does this fit
in with your plans, and can I have an offline
discussion with you regarding this.
I was a very early member of Lugnet, and I am
still having trouble with passwords and account
management so that I can post via the web ionterface
when I'm on the road.
Cheers, Ralph Hempel
