The µOLED-96-G2 is a compact and cost-effective display module using state-of-the-art Passive Matrix OLED (PMOLED) technology with an embedded GOLDELOX graphics processor that delivers ‘stand-alone’ functionality to any project. Powerful graphics, text, image, animation and other features are built into the GOLDELOX chip that delivers stand-alone functionality to any project.

Powerful graphics, text, image, animation and more features are built inside the GOLDELOX chip. The module is designed to work out of the box as a serial slave device or for you to write code in 4DGL (a high-level 4D Graphics Language) using the 4DGL-Workshop4 IDE (editor, compiler and downloader).

4DGL is a graphics-oriented language allowing you to write applications in a high-level language with syntax similar to popular languages such as BASIC, C and Pascal. The module offers modest but comprehensive I/O features that can interface to serial, analog, digital, buttons, joystick, sound generation and Dallas 1-wire devices.

The GOLDELOX processor on the display module can be re-programmed with different ‘Personality Module Micro-Code’ (PmmC) files for updates and future proofing. This process requires the use of a USB converter that uses the DTR signal to pulse the Reset line on the processor. Two USB-to-Serial converters that can plug directly into this module are available from the "Optional Recommended Products" list below.

Three different usage methods

• The Designer environment enables you to write 4DGL code in its natural form to program the display module.
• The ViSi visual programming experience enables drag-and-drop placement of objects to assist with 4DGL code generation and allows you to visualize how the display will look.
• The Serial environment is provided to transform the display module into a slave serial display module, allowing you to control the display from any host microcontroller or device with a serial port. Serial libraries are available for C, Pascal, PicAxe, and Arduino.

OLED Graphics Display Module Resources

• 4D Workshop4 IDE Tool: This is a free software tool for Windows. The 4D-Workshop4 IDE provides an integrated software development environment for the GOLDELOX processor and associated display modules. The IDE combines the Editor, Compiler, Linker and Downloader to develop complete 4DGL application code. All user application code is developed within the Workshop4 IDE. After clicking the above link, scroll down to find links to the software and the documentation of its various components. Some of the reference manuals, and the links to Arduino serial libraries, have versions for three different graphics chips; be sure to download the GOLDELOX versions. Also note that while the ViSi environment is supported by the GOLDELOX chip, the ViSi-Genie environment is not.
