New Display - ST7789V on TTGO - Inverted Colours #84

Open RichardPar opened 4 years ago

RichardPar commented 4 years ago

Hi there,

I got the ESP32 with an OLED display build on by TTGO. It has a pretty standard controller except the pixels are offset to get to location 0.0 (They are actually 52.40) I added code to offset the X and Y but now the colours seem inverted. Selecting TFT_BLACK results in writing in WHITE. I have tried using the function TFT_invertDisplay(INVERT_ON) but that does not seem to do anything. Is there another way to correct the colours ?

Added code for _offsets .. its not generic as this is an experiment.

I added pretty much full support for the TTGO T-Display here: https://github.com/jeremyjh/ESP32_TFT_library/pull/4
