I have a new Teensy 4.1 board in the works that uses the 3.5" ST7796 IPS display with FT6336 capacitive touch. A really nice upgrade over the typical ILI9341 setup. Higher resolution, better viewing angles and no need to calibrate the touch.
@KurtE I have been using your ST7796_t3 fork off Paul's ST7735_t3 library and it seems to be working fine from the somewhat limited testing I have done.
The 3.5" display does require the colors to be inverted ala tft.invertDisplay(true);. The 4.0" ST7796 display I tested worked without the colors being inverted. Might be IPS vs non-IPS related, but not a big issue either way other than you see the colors invert briefly at power up. I am also not using Reset in the constructor, the reset pin is just pulled high.
Any chance of getting your fork rolled into the upcoming Teensyduino 1.60 Teensyduino release as it seems pretty minor?
