**This product is NOT RECOMMENDED for new designs, and has been superseeded by the new μOLED-128-G2module**
The uOLED-128-G1(SGC) is a compact and cost effective all in one ‘SMART” serial display module using the latest state of the art Passive Matrix OLED (PMOLED) technology with an embedded GOLDELOX-SGC graphics controller that delivers ‘stand-alone’ functionality to any project.
Powerful graphics, text, image, animation and countless more features are built inside the module. It offers a simple yet effective serial interface to any host micro-controller that can communicate via a serial port. All screen related functions are sent using a simple protocol via the serial interface.
The serial platform allows users to develop their application using their favourite micro-controller and software development tools. In short, the uOLED-128-G1(SGC) offers one of the most flexible embedded graphics solutions available.
Note: The GOLDELOX processor on the Display module can be re-programmed with the latest PmmC configuration 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, such as any one of the following 4D Programming modules:
Warranty Note: PmmC or 4DGL programming should only be carried out using any one of the 4D Programming modules (4D Programming Cable, uUSB-MB5, uUSB-CE5). Any malfunction because of custom or third party USB to Serial converters or Serial(RS232) to Serial(TTL) level converters will void the warranty.
It also applies to all 4D products which require an interface from the PC to the module for testing using 4D Software Test Tools.
It applies to all the purchases on or after 1st of July 2011.

PmmC File: The PmmC file contains the low level micro-code information (analogy of that of a soft silicon) which define the characteristics and functionality of the GOLDELOX-SGC processor. All of the high level serial commands are part of the PmmC configuration file and future proofing and enhancements are available via PmmC updates. The PmmC file is programmed into the uOLED-128-G1(SGC) module via the serial port. - uOLED-128-G1SGC-R17.pmmc (for rev1g or below) - uOLED-128-G1hSGC-R17.pmmc (for rev1h or above)
DISP Config File: The GOLDELOX-SGC is factory configured to work with the onboard 1.5" touch display. The DISP config file contains information for the display hardware registers, embedded fonts, splash screen settings, screen saver, etc. Download and import this file into the DISP-Software-Tool to further customise the embedded fonts, the splash screen, the screen saver and other features. - Configuration Files
Simulation File: The simulation file can be imported into the FAT-Controller software tool to simulate all the functionality of the uOLED-128-G1(SGC) module on the PC. - Simulation Files
Software Tools: There are a number of different software tools available that assist in the development and operation of 4D products. Each tool has a dedicated function and depending on the application, a given tool may or may not be needed. The links below list all the different software tools relevant for SGC based modules. A detailed description along with details of when each tool should be used can be found within each product page. - 4D Workshop3 IDE - PmmC Loader - FAT Controller - Graphics Composer - DISP Tool - FONT Tool
GFX or SGC
How To Decide Between GFX or SGC
The architecture of the base GOLDELOX chip is such that it can be reconfigured to operate in 2 distinctively different ways. To configure the device, a PmmC (Personality Module Micro-Code) is downloaded via its serial port. There are 2 types of PmmC available for GOLDELOX.
SGC PmmC: By loading the SGC (Slave Graphics Controller) PmmC, the module is 'ready to go' by simply connecting it to the serial port of your favourite micro-controller, and sending serial commands to it. The Serial Command Set for GOLDELOX can be found here: GOLDELOX-SGC-COMMANDS-SIS-rev6.pdf
GFX PmmC: By loading the GFX (Stand-Alone Graphics Controller) PmmC, the module is then like a microprocessor which you program, using the 4DGL language (very similar to C), to control the internal graphics and external interfaces. The 4DGL language command set and functions for GOLDELOX can be found here: GOLDELOX-GFX2-4DGL-Internal-Functions-rev3.pdf
At any time, you can reload the GOLDELOX chip with either PmmC which allows you to explore the differences between the two configurations.
In general, documentation and PmmC's for both configurations (GOLDELOX-SGC or GOLDELOX-GFX2) for the uOLED-128-G1 module can be found in the 'Downloads' tab of each link here: uOLED-128-G1(SGC) : with GOLDELOX-SGC Slave configuration
