I just bought that display:
3_5-Inch-TFT-Color-Display-Screen-Module
But is not working with any examples and is reported by unsupported 0x2323 id. How could I make it working?
diagnose_TFT_support output:
Diagnose whether this controller is supported
There are FAQs in extras/mcufriend_how_to.txt
tft.readID() finds: ID = 0x2323
MCUFRIEND_kbv version: 2.9.8
This ID is not supported
look up ID in extras/mcufriend_how_to.txt
you may need to edit MCUFRIEND_kbv.cpp
to enable support for this ID
e.g. #define SUPPORT_8347D
New controllers appear on Ebay often
If your ID is not supported
run LCD_ID_readreg.ino from examples/
Copy-Paste the output from the Serial Terminal
to a message in Displays topic on Arduino Forum
or to Issues on GitHub
Note that OPEN-SMART boards have diff pinout
Edit the pin defines in LCD_ID_readreg to match
Edit mcufiend_shield.h for USE_SPECIAL
Edit mcufiend_special.h for USE_OPENSMART_SHIELD_PINOUT
LCD_ID_readreg output:
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)
