5 years ago Why are you compiling Adafruit_TFTLCD.cpp ? Your question is about MCUFRIEND_kbv.
Teensy3.x have an "official" baseboard from SparkFun with Arduino headers. If there was a commercially produced baseboard for Teensy++ 2.0 I would put the support in "utility/mcufriend_shield.h"
I do not own a Teensy++ 2.0 but it appears to use a AT90USB1286. I have to rely on owner feedback. If you post the defines from your readreg sketch with the correct sketch output, I can add support as a SPECIAL.
David.
Edit. Looking at the Teensy++ pin mapping, it is very straightforward.
This could go in mcufriend_shield.h. Obviously untested.

Hello! Your library works well with Teensy 3x, but I was wondering if it could support T++ 2.0. I have an 0x8230, and the screen fills (with blue, but hey) during the LCD_ID_readreg test.
When I compile graphicstest with T++ I get:

Error compiling for board Teensy++ 2.0. `
I tried hacking the include files to support the chipset, but I wasn't sure what to do!!!
Thank you
