Yes, it should be a config option.

-static char fontmap[95][12] = {

Yes please do so, this way people could have 'personalised' font maps.
Still, offer a config option to hardcode the fontmap file.
And a further improvement would be to support multibyte-strings for
localisation.
I would recommend having a simple font file like:
# Lines starting with # are ignored
# So are empty line
0x12345678 0x01 0x02 0x03 0x04 0x05 0x06 0x07 0x08 0x09 0x0A 0x0B 0x0C
where the first hexa number is the UTF-8 sequence to be recognised, and the
folowing single bytes are the patern to draw.
Of course, the font table will be sparse, and finding the character to
draw will need (smart) iteration throught the table. And because the table
might miss entries for some characters, have a default character be drawn
(eg 0x00000000).
Then, in the build procedure, have a litle script that parses that file format
and outputs either a .h file if the font is hardcoded, or a binary blob if the
font is dynamicaly loaded at run time.
So to sum up:
- text rendering should be configurable
- the font map can be either hard-coded to use the default font map,
or it can be dynamically loaded at runtime, so the user can create
their own font maps
- font map should be UTF-8 compliant, to allow localisation.
- the source font map format should be documented (at least in the
default font map).
Of course, this is but my opinion. :-)

Yann E. MORIN.
