You might also have a look at Text.c

There's no need to use a framebuffer and display its contents with the flush()-
call (as in MatrixOrbital.c), you can directly write to the display in the put()-
and bar()-functions, and use an empty flush()-function. But if you have a limited

'character reduction' or similar stuff, you will have to use a framebuffer and
the flush()-call.
