waveshareFontGenerator
This tool can convert ttf fonts to a sFont struct needed for waveshare ePaper displays.
This is a prototype but workes fine for me.
As the epaper lib support only non-proportional fonts, finding the correct width can be tricky.
You can configure the sizes with command line arguments (go run main.go -h).
GO 1.13 is needed to compile this tool.
Usage example:
go run main.go -f /usr/share/fonts/myfont.ttf > myCustomFont.h
