Fonts
How to add new symbols:
- Browse the cheat sheets and pick symbols
- For each symbol, add its hex code (0xf641 for the ‘Ad’ icon, for example) to the Range list in the
fonts.json file
- Convert this hex value into a UTF-8 code
using this site
- Define the new symbols in
src/displayapp/screens/Symbols.h:
static constexpr const char* newSymbol = "\xEF\x86\x85";
inside fonts, there is a dictionary of fonts,
and for each font there is:
- sources - list of file,range(,symbols) wanted (as a dictionary of those)
- bpp - bits per pixel.
- size - size.
- patches - list of extra “patches” to run: a path to a .patch file. (may be relative)
- compress - optional. default disabled. add
"compress": true to enable
Navigation font
navigtion.ttf is created with the web app icomoon by importing the svg files from src/displayapp/icons/navigation/unique and generating the font. lv_font_navi_80.json is a project file for the site, which you can import to add or remove icons.
