LVGL Version Issues – Errors in Provided Code for 5-Inch Display

abbiewang · February 27

Hello,

I recently purchased the CrowPanel ESP32 5-inch display and have been trying to run the example code provided for LVGL and SquareLine Studio in the following sources:

GitHub Tutorial Code (from YouTube, I practice the code by order)
Demo Code from Elecrow Wiki

However, both versions resulted in numerous compilation errors, most of which seem to be caused by outdated LVGL commands that are no longer recognized in the latest LVGL library.

I also tried using the corresponding LVGL version specified for the demo code on the wiki, but despite successfully compiling, the screen remains empty with no visible output.

Could you provide an updated version of the code that is compatible with the current LVGL release? If not, could you clarify which LVGL version is required for the provided code to function correctly?

Thanks in advance for your help!
