FTDI EVE Library

The FTDI EVE Library is a fully open-source library and UI framework for the FTDI FT800 and FT810 graphics processor.

Although the library has been developed within Lulzbot for providing a user interface for Marlin, the library has been written so that it can be used in any Arduino sketch.

The library is split into two parts. The “basic” API provides a shallow interface to the underlying FTDI hardware and command FIFO and provides low-level access to the hardware as closely as possible to the API described in the FTDI Programmer’s Guide.

The “extended” API builds on top of the “basic” API to provide a GUI framework for handling common challenges in building a usable GUI. The GUI framework provides the following features:

• Macros for a resolution-independent placement of widgets based on a grid.
• Class-based UI screens, with press and unpress touch events, as well as touch repeat.
• Event loop with button debouncing and button push visual and auditory feedback.
• Easy screen-to-screen navigation including a navigation stack for going backwards.
• Visual feedback for disabled vs enabled buttons, and custom button styles.
• A sound player class for playing individual notes or complete sound sequences.
• Display list caching, for storing static background elements of a screen in RAM_G.

See the “examples” folder for Arduino sketches. Modify the “src/config.h” file in each to suit your particular setup. The “sample_configs” contain sample configuration files for running the sketches on our 3D printer boards.
