Strange 2,4" TFT LCD (Mcufriend)

Hi,

I have a some years old MCUfriend (35702) 2,4" TFT LCD display. I tried to get it work some times, but without success; now i finally understand the output of LCD_readreg.ino :smiley: But still can't get display on the screen.

My LCD_readreg report is :
Read Special Registers on MCUFRIEND UNO shield
controllers either read as single 16-bit
e.g. the ID is at readReg(0)
or as a sequence of 8-bit values
in special locations (first is dummy)

diagnose any controller

I tried several settings read on the MCUfriend threads by David Prentice, but cannot get any display.

Does anyone have this model and have information about how i can drive it? :smiley:

Thanks for any help :slight_smile:
