Hello. I was playing around with an Adafruit ESP32 V2 and the 2.4" tft display that uses the ST7789V driver and for some reason my colors are reversed. communication is 4-wire SPI. Pixel size is 320x240. The only thing I can think of is that the display is 18-bit color and I am using the adafruit_gfx library that is 16-bit color? And if so, how would I go about tinkering this?
