4.3" Serial-Platform LCD-TFT Module (optional Touch)
This product us RoHS compliant This product is PbFree


**This product has been renamed to be the μLCD-43, 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 μLCD43(SGC) is an intelligent graphics display, that harnesses the power to deliver a diverse range of features in a single compact cost effective unit. Embedded at the heart of the design is the PICASO-SGC processor, which supplies powerful graphics, text, images, animation and countless more features. It offers a simple yet effective serial interface to any host micro-controller capable of serial communication. As such, the μLCD43(SGC) allows users to develop an application using their favourite micro-controller and software development tool. Features include; a 4.3'' TFT 480x272 touch screen display, audio, micro-SD card connector, an expansion port along with a series of GPIO. The μLCD43(SGC) serves as the perfect solution to be deployed at the forefront of any product design, requiring a brilliance of colour, images or text on a 4.3'' widescreen display.


Note: The PICASO 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 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.

Data Sheets: The latest data sheets for the module are available here:
     - uLCD43-SGC-DS-rev4.pdf
     - PICASO-SGC-COMMANDS-SIS-rev11.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 PICASO-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 μLCD43(SGC) module via the serial port.

    - uLCD-43PCTSGC-R22.PmmC (Capacitive Touch)

DISP Config File: The PICASO-SGC is factory configured to work with the onboard 4.3" 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.

How To Decide Between GFX or SGC 
The architecture of the base PICASO chip  is such that it can be reconfigured  to operate in two distinctively different ways. To configure the device, a PmmC (Personality Module Micro-Code) is downloaded via its serial port. There are two types of PmmC available for PICASO.


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 PICASO 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 PICASO can be found here:

At any time, you can reload the PICASO chip with either PmmC which allows you to explore the differences between the two configurations.

In general, documentation and PmmC's for both configurations (PICASO-SGC or PICASO-GFX2) for the μLCD43 module can be found in the 'Downloads' tab of each link here:
