Display and graphics component for ESP32 with SPI, I2C, parallel and MIPI-DSI display buses, virtual screens, drawing primitives, fonts, handwritten text and morphing
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
A small engine of 2D and 2.5D games on top of DGX: an indexed frame sent by its changes and scaled, pictures from a pack in flash, actors living by animation scripts, tiles, masks, a world that lives on, dialogs, a sound mixer
