Just wanted to share that I’ve tweaked a library to support those nice TFT IPS screens that are based on the ST7789 chip. I’ve organised it as a Particle project with supporting libs included: https://github.com/jenschr/Arduino-ST7789-Library I made it so that it does not require all of the ST7735 libs to go with it, but it requires mfGFX.
I’ve tested it with 135 x 240 and 240 x 240 pixel versions of the screens. Will likely work with other Particle devices, so tag them in this thread if you test with something else.
Enjoy and ping me if you find errors
