Hi,
i have a "ILI9341" 2.8'' Display with resistive touch from china (aliexpress).
The model is "TJCTM24028-SPI". The board looks like the boards on the smaller displays, but with the additional touch-ic (currently unused and not connected).
The graphics-test runs fine, display works and shows the graphics.
But strange is, SDO(MISO) seems to be not connected ? The diagnostic output is all 0xff, sometimes 0x00.
Display Power Mode: 0xFF
MADCTL Mode: 0xFF
Pixel Format: 0xFF
Image Format: 0xFF
Self Diagnostic: 0xFF
Is my display defective, or are there exsisting variants without connected miso ?
Does anyone but me see this behavior with these displays?
Normally, this shouldn't be a big problem, but i want to read display content back..
