The µOLED-128-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.
The module is designed to work out of the box and ready for your code written 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 high-level code with syntax similar to popular languages such as BASIC, C and Pascal. The Workshop IDE also features the ViSi-Genie, a drag-and-drop graphical interface that will create 4DGL code for you — all you need to do is place pre-made objects onto a simulated image of the display, size and set parameters to your liking, then a single click will generate the 4DGL code to make that object functional.
Using the Workshop IDE, the module also can be loaded with a Serial Application that transforms it into a Serial Slave to virtually any serial host.
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 also can be re-programmed with different ‘Personality Module Micro-Code’ (PmmC) files for updates and future proofing. The processes of converting to a serial slave, updating the PmmC firmware, or downloading your 4DGL program code all require connection 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 4D Systems Workshop 4 IDE supports multiple development environments, to cater for different user requirements and skill level.
By default, the module will come ready for Serial usage. You can change environments or customize the serial firmware using one of the optional USB-to-Serial converters and the Workshop 4 IDE software.
- 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.
