The cst816 touchscreen platform allows using the touch screen controllers based on the CST816 series of chips with ESPHome. The I²C <i2c> is required to be set up in your configuration for this touchscreen to work.
This controller is used in the Lilygo T-Display S3 AMOLED. The component should work with CST816T, CST816S, CST820 and CST716 controller chips.
