2.8" 240x320 Display with touch and ST7789 driver has colors inverted

[pdfelen]

With some help browsing the internet I did found a solution for my problem with the 2.8" 240x320 display. After initialization the colors are inverted.

In file "Adafruit_ST7789.cpp" on line 72 the command structure 'generic_st7789' holds setting ST77XX_INVON, for my screen this needs to be ST77XX_INVOFF.
After changing that my screen works.
For now I duplicated the Adafruit_ST7789 .cpp and .h files into Adafruit_ST7789_28.cpp and .h and made the change. A more permanent solution would be appreciated where this is user configurable.

Thanks

I have exactly the same problem.
This setting must also be changed for the following displays for electronics housings from Phoenix Contact!
