OMMenuMgr on Teensy 3.1, 7735 SPI TFT, and NunChuck Buttons

[mrdevis]

Hi,
Don't know if this library is still actively supported. I have extended your library with a Nunchuck controller as Button Interface (works fine, adding a NunChuck to the Analog and Digital variants), but I'm a stuck on how to get the menu text onto a 128x160 tft display (ST7735).

All MENU_ITEM text is garbled, except for the (hardcoded) MENU_PROMPT, and text directly written onto the display. So I guess it somewhere in the passing of the MENU_LIST to the uiDraw callback. I don't really look thru the referencing there, so I would be terribly grateful for some pointers (no pun intended). Something special on the Teensy in memory, different from Arduino?

Thanks in advance, Jeroen
