Hi, i have a TFT display, when i tried run LCD_ID_readreg, this return to me from serial:
Read 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)

But, when i'll try run "TouchScreen Calibr native", serial output is:
TouchScreen.h GFX Calibration
Making all control and bus pins INPUT_PULLUP
Typical 30k Analog pullup with corresponding pin
would read low when digital is written LOW
e.g. reads ~25 for 300R X direction
e.g. reads ~30 for 500R Y direction
BROKEN TOUCHSCREEN
ID = 0x9486
Why my TouchScreen do not work?
