Using GFX Library for Guition JC8048W550

[memchi]

There is a sample project to download, but with some outdated and also adapted versions of ESP32 / GFX / LVGL and others: http://pan.jczn1688.com/directlink/1/HMI%20display/JC8048W550.zip

The GFX version in the zip is labeled 1.2.9 but with some adaptions. If I install the 1.2.9 version i do run into this problem:

When i install latest (1.4.7 for now) i run into this problem:

This examples instantiates bus and gfx as below, but "Arduino_ESP32RGBPanel" is behind a "#if (ESP_ARDUINO_VERSION_MAJOR < 3)". How to translate code below to the modern version? (I could live of course with a workaround, Downgrading ESP32 to 2.0.17 would be the worst)

please use arduino-esp32 2.x

Thank you for fast response. Had to adapt things, but it works now. Great! Is there any plan to be compatible to newest versions (ESP32 / GFX / LVGL)?
