100's of compile Errors
I am trying to get the Lesson 3 demo to run for the 7" Advance HMI display.
I have copied across all the libraries, set the correct board type & settings, copied across the ESP32S3_120M file etc etc.
But I just get loads of compile errors, a few examples below:-
C:\Users\paul\OneDrive\Electronics\01 - Sketches\03 - CrowPanel\BigInch_LVGL\ui_Screen1.c: In function 'ui_Screen1_screen_init':

Hello ，
The error message indicates that font 40 is being used—this is a font you defined, right? You need to enable this font setting in the lvgl_conf.h file.
Additionally, did the elecrow code successfully compile?
This is not my code, it is the demonstration code which I downloaded from Elecrow's tutorial video links. Biginch_LVGL.
