## Generate the fonts:
* Open the [LVGL font converter](https://lvgl.io/tools/fontconverter)

* Click on Convert, and download the file `jetbrains_mono_bold_20.c` and copy it in `src/DisplayApp/Fonts`
Add new symbols:
* Browse the [cheatsheet](https://fontawesome.com/cheatsheet/free/solid) and find your new symbols
* For each symbol, add its hex code (0xf641 for the 'Ad' icon, for example) to the *Range* list (Remember to keep this
readme updated with newest range list)
* Convert this hex value into a UTF-8 code
using [this site](http://www.ltg.ed.ac.uk/~richard/utf-8.cgi?input=f185&mode=hex)
* Define the new symbols in `src/DisplayApp/Screens/Symbols.h`:
```
static constex char* newSymbol = "\xEF\x86\x85";
```
#### Navigation font
To create the navigtion.ttf I use the web app [icomoon](https://icomoon.io/app)
this app can import the svg files from the folder *src/displayapp/icons/navigation/unique* and creat a ttf file the
project for the site is *lv_font_navi_80.json* you can import it to add or remove icons
You can also use the online LVGL tool to create the .c
ttf file : navigation.ttf name : lv_font_navi_80 size : 80px Bpp : 2 bit-per-pixel range : 0xe900-0xe929
$lv_font_conv --font navigation.ttf -r '0xe900-0xe929' --size 80 --format lvgl --bpp 2 --no-prefilter -o
lv_font_navi_80.c
#### I use the method above to create the other ttf
