4D Systems GOLDELOX and PICASO Embedded 4DGL Graphics Controllers are powered by a highly optimized soft core virtual engine, Extensible Virtual Engine. EVE is a proprietary, high-performance virtual processor with a high-level language that is easy to learn and simple to understand, yet powerful enough to tackle many embedded graphics applications.
These controllers offer modest but comprehensive I/O features and can interface to SPI, I²C, serial, digital, analog, buttons, joystick, Dallas 1-wire devices, and more. All of the display built-in driver libraries implement and share the same high-level function interface. This allows the GUI application to be portable to different display controller types. 4D Systems' software development IDE, Workshop4 IDE PRO, provides an integrated software development platform.
