µGFX

GUIslice is a very lightweight platform-independent GUI designed for embedded displays, from an 8-bit Arduino with 2KB RAM to the Raspberry Pi. The library supports creation of multiple pages of buttons, text, images, checkboxes, sliders and other graphics primitives. New UI / widget types can be created easily. The core GUIslice library is written in pure C. GUIslice is intended to be used with Raspberry Pi and all Arduino adaptations (ATmega, STM32duino, ESP8266 / NodeMCU, ESP32, Adafruit Feather M0, nRF52, etc.). In addition to RPI, GUIslice works in other LINUX-based platforms including BeagleBone Black and Virtual Machines (VM). The LINUX operation supports framebuffer-based displays without X-windows / X11. Touchscreen controls are supported (both resistive and capacitive), but it is also possible to run on non-touch displays. Keyboard / GPIO / button navigation of the GUI is also available.

An embedded GUI (Graphical User Interface) is a software interface that is designed for use on an embedded system, such as a microcontroller or a single-board computer. Embedded GUIs provide a graphical interface for interacting with the system and enable users to control and monitor the system through visual elements such as icons, buttons, sliders, and text fields. MicroEJ embedded GUI solution provides your customers with a beautiful look and feel and high performance, on markets such as wearables, home appliances, smart homes, medical, smart printers, and more generally speaking any kind of small electronic products. Take advantage of impeccable, ultra-fast execution embedded GUIs that will guarantee your customers a great user experience. Adding to the benefits of stunning graphics, rich animations, and interactions, MicroEJ’s portability across different electronics allows you to leverage your design investment by re-using the same graphical widgets for all your products.
