CrowPanel 7.0" Black Screeen

Guille818

Hello, The display was working with the demo pages, 3.0 Ver.
I Upload a program from the demos, since then, I see only black screen on the display.
I have not errors on the compilation and the upload goto good end.
I copy the "libraries" from the "CrowPanel-7.0-HMI-ESP32-Display-800x480-master" then I found on the Wiki.
On the serial I have some error, image attached.

Help Please, Thanks.

Hello,
I was able to make it work with the Demo Programs.
I load all the libraries and boards as described on the Wiki, photo attached.
Use the files and demos from the next link
https://github.com/Elecrow-RD/CrowPanel-7.0-HMI-ESP32-Display-800x480
But inside this there are many lib files

Is possible to indicate better which one is for my display, thanks.
