General discussion

Hi guys,
I need to add support to latin characters, but without loosing the the already formatated display.
So im trying to import the same font, but with all the chars i need.
I’m trying to use Google Fonts but i dont know which one is equal to the default lvgl font. Can u guys help me chose?

Best regards

I can save you the trouble. :wink: The TTFs are right here.

But those font dont have the ‘ç’ and ‘ã’ char that i need. I was trying to get the complete version.

The TTF is the same one that Google provides, as far as I know. We just don’t convert all the characters to the LVGL font format to save flash space. You have to reconvert it using the LVGL font converter.

I did check it and the TTF does have the c with cedilla (ç) at the very least.

Oh, thank you very much, i was able to generate the font again with the desired characters. One more thing, if i use [built_in_font_gen.py] with the Montserrat-Medium.ttf, am i able to change the default font range?

You can use the -r flag.
See

 ./built_in_font_gen.py --help
usage: built_in_font_gen.py [-h] [-s [px]] [--bpp [1,2,4]]
                            [-r start-end [start-end ...]]
                            [--symbols sym [sym ...]] [--font [file]]
                            [-o [file]] [--compressed] [--subpx]

Create fonts for LittelvGL including the built-in symbols. lv_font_conv needs to be installed. See https://github.com/littlevgl/lv_font_conv
Example: python built_in_font_gen.py --size 16 -o lv_font_roboto_16.c --bpp 4 -r 0x20-0x7F

optional arguments:
  -h, --help            show this help message and exit
  -s [px], --size [px]  Size of the font in px
  --bpp [1,2,4]         Bit per pixel
  -r start-end [start-end ...], --range start-end [start-end ...]
                        Ranges and/or characters to include. Default is 0x20-7F (ASCII). E.g. -r 0x20-0x7F, 0x200, 324
  --symbols sym [sym ...]
                        b'Symbols to include. E.g. -s \xc3\x81\xc3\x89\xc5\x90'
  --font [file]         A TTF or WOFF file
  -o [file], --output [file]
                        Output file name. E.g. my_font_20.c
  --compressed          Compress the bitmaps
  --subpx               3 times wider letters for sub pixel rendering
