The fonts are created with Fony.exe (http://hukka.ncn.fi/?fony) because Fontforge didn't do what I want (probably lack of experience). In Fony export the fonts to bdf-format. Maybe another one can edit them with Fontforge. Then run make_fonts.bat what calls bdf2u8g.exe with the needed parameters to produce the .h files. The .h files must be edited to replace '#include "u8g.h"' with '#include ', replace 'U8G_FONT_SECTION' with 'U8G_SECTION', insert '.progmem.' right behind the first '"' and moved to the main directory. How to integrate a new font: Currently we are limited to 256 symbols per font. We use a menu system with 5 lines, on a display with 64 pixel height. That means we have 12 pixel for a line. To have some space in between the lines we can't use more then 10 pixel height for the symbols. For up to 11 pixel set TALL_FONT_CORRECTION 1 when loading the font. To fit 22 Symbols on the 128 pixel wide screen, the symbols can't be wider than 5 pixel, for the first 128 symbols. For the second half of the font we now support up to 11x11 pixel. * Get 'Fony.exe' * Copy one of the existing *.fon files and work with this. * Change the pixels. Don't change width or height. * Export as *.bdf * Use 'bdf2u8g.exe' to produce the *.h file. Examples for the existing fonts are in 'make_fonts.bat' * Edit the produced .h file to match our needs. See hints in 'README.fonts' or the other 'dogm_font_data_.h' files. * Make a new entry in the font list in 'dogm_lcd_implementation.h' before the '#else // fall back' #elif ENABLED(DISPLAY_CHARSET_NEWNAME) #include "dogm_font_data_yourfont.h" #define FONT_MENU_NAME YOURFONTNAME #else // fall-back * Add your font to the list of permitted fonts in 'language_en.h' ... || ENABLED(DISPLAY_CHARSET_YOUR_NEW_FONT) ... )
