What do you want to achieve?
When We export the UI through squareline studio, the font variable is not correct.
By default it comes like:
UI_FONT_DATE-30
instead of
UI_FONT_DATE_30
And because of this Arduino throw compiler error:
error: missing binary operator before token “1”
10 | #define UI_FONT_DATE-40 1
I’m running on Windows 11, lvgl v8.4.0
