Interfacing Waveshare 1.47" LCD With ESP32 & LVGL | Aravind VS

Interfacing a Waveshare 1.47 inch rounded corner LCD display module with ESP32 & LVGL library

Hello, I'm just trying to run a 1.69 inch Waveshare Display with ESP32 boards. So I wanted go give your project a try. But unfortunately it throws me an error that lv_conf.h is not found. This file isn't in the lvgl folder. You wrote "Assuming you have LVGL installed and configured correctly(skipping LVGL setup for brevity)" What do you mean by this? I installed the library with the Arduino library manager ..

ok, I found the installation guide for lvgl library and could integrate it successfully. But now I get lot of errors while compiling the script:

@Martius108 i guess u should downgrade the lvgl version, mine is working using this version : lib_deps = moononournation/GFX Library for Arduino@^1.4.6 lvgl/lvgl@8.1.0
