4D Systems GOLDELOX & PICASO 4DGL Graphics Controllers

4D Systems GOLDELOX and PICASO Embedded 4DGL Graphics Controllers are designed to interface with OLED and LCD display panels. Powerful graphics, text, image, animation, and other features are built right inside these chips. These controllers offer simple plug-and-play interfaces to many 8-bit and 16-bit 80-Series color LCD and OLED displays. These chips are designed to work with minimal design effort, and all of the data and control signals are provided to interface directly to the display. The user can simply choose a display and interface it to the GOLDELOX or PICASO on the application board.

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.
