Sorry, but I'm a bit busy at the moment. I will test it as soon as possible.

Hi @isthaison,

I tested this project and it worked very well. But, to make it more official, there are some suggestions:

1. Please rebase the commits on the master branch to avoid the conflicting changes caused by the merge from the master branch.
2. We should remove the large LVGL demo source files, as the "demos" folder contains numerous photos. It would be more beneficial to provide a simple example, such as porting.ino, and include comments to guide users in using LVGL demos.
3. It's necessary to update the README file. At present, the project is specifically designed for the BOARD_ESP32_S3_LCD_EV_BOARD_V1_5 development board. I recommend using the default ESP_Panel_Board_Supported.h and ESP_Panel_Board_Custom.h, while also providing instructions on how to replace the development board if needed.

It's totally fine if you are unfamiliar with the above process, I can help you with the modifications. Thank you once again for your contribution.

Thank you! I noticed a few errors in the pre-commit stage, so I took your commit and addressed them in pull request #42. Once I'm done with the documentation, I'll proceed to merge it.
