I have been working several days to get a working demo sketch for the MATouch 2.1" Rotary Touchscreen to function via platformIO. I have tried numerous configurations, versions of libraries, various board.build options, and each time I end up with a backlit screen.
Per their Wiki, Arduino IDE 1.8 must be utilized when working with the arduino IDE, ESP32 arduino core 2.0.6, and GFX for Arduino v1.3.1 or 1.3.6-1.3.8.
The latest attempted uploaded code is this:

Last attempted platform.ini:
[env:esp32-s3-devkitc-1]
platform = espressif32@6.0.1
board = esp32-s3-devkitc-1
framework = arduino
lib_deps = moononournation/GFX Library for Arduino@1.3.8
Something that does stand out to me is that the configuration detailed toward the bottom of the wiki for utilizing platformIO specifies a verison of the board with no PSRAM, although the arduino board configuration specifies it.
The chip itself is an R8, which I think has no psram?
I attempted to utilize the esp32 dev board and configure the board.build in the ini file, but I succeeded in boot looping the MATouch. I became frustrated and deleted all of the projects, so it would take me a few minutes to reference board.txt and figure out what I had done.
I am very curious about board_build.partitions as it should be 16M per the board.txt and arduino board selection. I have noticed that the addresses are different when the board is being flashed in pio or arduino ide.
I can flash from pio, get a blank screen, alt-tab to the arduino IDE and flash, and have a functioning user interface.
I have several threads I have referenced but I’m a new user and cannot post them.
I need help with what I am missing please. I am a novice and work on this in my spare time. My plan was to utilize a UI generated in Squareline Studio, but I cannot get it or any of the demos to successfully flash through pio.
