I am trying to add a few symbols. To get started I followed what the manual describes and tried to add the USB symbol, but fail. Fist of all, the link to the file converter is broken. I’ve used the one linked in the Tools section of the website navigation instead. Selected the Font-Awesome font, added 0xf287 for the USB symbol into the range field, and got presented with a usb.c file in my downloads. It only has 85 lines, I do not see anything that would be complex enough to describe the shape of the USB logo in it, so I already suspected this might not work at all, but gave it a chance because maybe there’s just some magic going on that I have yet to understand.
Had to edit the file to include
<lvgl.h> instead of
"lvgl/lvgl.h" (VScode/PlatformIO), added
#define LV_SYMBOL_USB "\xEF\x8A\x87" to my lv_conf.h, changed one working symbol with
LV_SYMBOL_USB. Everything compiled, uploaded and executed normally. Only as expected the Symbol was gone, no USB symbol displayed.
Is there anything I am missing?
