CST826 touchscreen support for 2.1" Round TFT Display
from Adafruit Industries · host Adafruit Industries
Our cute 2.1" round 480x480 TFT display (https://www.adafruit.com/product/5792) has a CST826 capacitive touchscreen overlay - different than the other screens that all have Focaltech FT6336U or similar. Thanks to MakerMelissa we now have support in both Arduino (https://github.com/adafruit/Adafruit_CST8XX_Library) and CircuitPython (https://github.com/adafruit/Adafruit_CircuitPython_CST8XX)! We also got a version of our 4" 720x720 display (https://www.adafruit.com/product/5793) with capacitive touch. Unfortunately this one doesn't have the same 'integrated' style where the CTP pads go through the 40-pin connector, bot rather they're on a separate 6-pin 0.5mm pitch tail. Still, it's worth the effort, so we'll make a lil breakout for the touch connector so you can plug it into the QT port.
