Thanks, Jim. It works.
Nice the features of displaying the current time (0x04), which makes me thinking that maybe the SP has an internal font generator...? In any case, I used the Freetype-generated bitmap, already available in my project, for the fonts (with FT_RENDER_MODE_MONO, since we can't display the anti-alias with binary pixels!). Results are good in this way.
In any case, I'll look into an upgrate to the SPP.
