**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 uLCD-144-G2(SGC) is a compact and cost effective all in one ‘SMART” serial display module using the latest state of the art TFT LCD 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 uLCD-144-G2(SGC) offers a flexible embedded graphics solution.


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.

Product Brief: An informative Brief of the uLCD-144-G2(SGC) module is available here:
     - uLCD-144-G2(SGC)-Product-Brief-rev1.pdf

Data Sheets: The latest data sheets for the module are available here:
     - uLCD-144-G2SGC-DS-rev1.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-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 uLCD-144-G2(SGC) module via the serial port.

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