Thanks for setting up the CVS project. I promise to start using it :-)

Yep, it still works the same way. The main change was to generalize the
character drawing code to draw arbitrary bitmaps, so I could draw icons,
etc. A character is just a bitmap, so lcd_string() now calls
lcd_bitmap() for each char.

I did change the format of the memory buffer to make the code easier.
(X and Y indices are swapped from the old code.) So if you have code
that depends on this, a small change is needed.

Sounds like a good idea to keep them separated. Maybe another directory
for the firmware implementation? As the project grows, I'm sure we'll
want to separate out other major pieces of the code.

Sounds good. We could use this to get started working on browsing UI.
There's plenty of work to do.

Thanks,
Gary
