Funny i usually check to see if any updates in the smartmatrix git page but i must have missed this.
AnimatedGIFs has it’s own repo, which is included as a subrepo in the SmartMatrix Library repo. I’ll only update the subrepo in SmartMatrix Library when I’m doing a full release of the Library.
Regarding Fonts, documentation is sparse:
note on use: Added -s option to tweak output to match format needed for SmartMatri… · pixelmatix/bdf2c@b07deb7 · GitHub
e.g. ./bdf2c -s -n fontname -b < font.bdf > font.c
You don’t have to replace a font, but that’s probably an easy way to add a font you want to SmartMatrix. You can add a new one to the list, but all fonts are included in program memory as of now. It’s on my list to only link fonts used in a sketch.
