Touch input for DGX displays: the fingers of a touch panel as fingers of the display, turned with the screen; a calibration measured on the board; gestures in millimetres; buttons the program draws; a translucent game pad in a layer of DGX and a keyboard on the display, with editors of their layouts and looks; a GSL3680 driver and any esp_lcd_touch panel
LVGL on the displays of DGX: SPI, QSPI, parallel and MIPI-DSI panels as LVGL displays, and the touch panels of DGX-DI as LVGL input devices, with no task and no lock of its own
