Thank you!

Can you help change the board.TFT_TIMINGS["frequency"] to 16000000? Having 12500000 is making the board display a white screen in the ESP32-8048S050C_I. Can I assign this value at startup?
I compared and tested the factory default program with 12.5M value in Arduino IDE, it is having the same effect. Please help change this to 16M

@sandzco Here is a build that changes the display SPI frequency to 16 MHz. Could you test it? You'll need to unzip it first.

@dhalbert It worked like a charm!
Not sure if I am at fault or if this is a new version, I bought this from Guiton store instead of Sunton. Thanks for the files!
