Hi @Snoopy-HSS,

Sorry for the late. Please refer to the documentation and configure the corresponding files based on your development board type before using the ESP_Panel drivers.

Did all the config.
But getting this undefined reference error...

Using the ESP_LCD.json as Board in PIO

Was the ESP_PANEL_USE_SUPPORTED_BOARD macro enabled as well?

You are probably not using the default example from this repository, right? Based on the error log you provided, the example includes a main.cpp file, but the default example in this repository does not have it. I suggest trying the default example from this repository first for testing.

Same if I user app.cpp instead of main.cpp

with platform = https://github.com/pioarduino/platform-espressif32/releases/download/53.03.11/platform-espressif32.zip it works...

Although I cannot reproduce your issue, the platform link you provided also works and supports Arduino v3.1.1. I will use this link in the new version. Thanks for sharing!
