Hello,

Two days ago, I purchased 2 LILYGO ESP32-S3 Round Display Touch Screen T-RGB screens, one 2.1 inch screen purchased from AliExpress and the other 2.8 inch screen purchased on the LILYGO website: Order LILYGO -17864

I do not want to use Arduino IDE but instead I will use Visual Studio Code, in which I have just installed the Extensions of the Espressif ESP-IDF libraries and that of LilyGo-RGB.
I can now compile examples of these libraries without problem with Visual Studio Code.

I started to look at the code a little bet and I noticed that the ST7701S screen from Sitronix can support several color formats: 16bits, 18bits and 24bits RGB interface.

LiLYGO mentions on their site that the ESP32-S3 T-RGB screen is configured in 18 bit RGB interface.

My question :

Is this configuration fixed by the hardware or is there a configuration file that I can modify to configure the screen to operate in 16bit RGB colors ?

I would like to use 16-bit color format instead of 18-bit!

Thank you in advance for your answer.

Christian
