**This product has been renamed to be the μLCD-144-G2, the terms SGC and GFX are no longer applicible as of December 17th 2012, unless existing customers wish to remain using the Workshop 3 Software**  

The µLCD-144-G2(GFX) is a compact and cost effective  display module using the latest state of the art LCD (TFT) technology with an embedded GOLDELOX-GFX2 graphics processor that delivers ‘stand-alone’ functionality to any project. Powerful graphics, text, image, animation and countless more features are built inside the GOLDELOX-GFX2 chip.

The module is designed to work out of the box and you are now ready to write your code in 4DGL (a high level 4D Graphics Language) using the 4DGL-Workshop3 IDE (editor, compiler, linker and downloader). This will save weeks even months of development time on your next embedded graphics project.

4DGL is a graphics oriented language allowing the developer to write applications in a high level language, 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, analogue, digital, buttons, joystick, sound generation and Dallas 1-wire devices. In short,  the µLCD-144-G2(GFX) 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 (as well as 4DGL program downloads). 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 CableuUSB-MB5uUSB-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.

     - GOLDELOX-GFX2-4DGL-Internal-Functions-rev5.pdf
     - 4DGL-Programmers-Reference-Manual-rev4.pdf

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-GFX2 processor. The chip-resident 4DGL functions 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-144-G2(GFX) module via the serial port.

FONT Software Tool: This is a free software tool that can assist in the conversion of any Windows fonts into the bitmap format that can be used by the GOLDELOX-GFX2. The converted font set can then be imported into the user 4DGL application code.
     - FONT Tool link

Graphics-Composer Software Tool: This is a free software tool for Windows. This software tool is an aid to composing a slide show of images/animations/movie-clips (multi-media objects) which can then be downloaded into the memory card that is supported by the GOLDELOX-GFX2. The multimedia objects can then be called within the user application 4DGL program.

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.


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:

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:

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-144-G2 module can be found in the 'Downloads' tab of each link here:
