Most LCD displays now have embedded touch screen controllers that can be interfaced through I2C or SPI buses. The ConnectCore 6UL SBC Pro supports external Goodix capacitive touch controller for the AUO 10.1" LVDS LCD display, connected through port I2C1. It also supports touch controller for Fusion 7" and Fusion 10.1" LVDS LCD displays, but not by default. See Enable support for a Fusion display for details.
