GOLDELOX-SGC Embedded Serial Graphics Controller

The GOLDELOX-SGC is an intelligent Serial Graphics Controller designed to interface with many popular OLED and LCD display panels. Powerful graphics, text, image, animation and countless more features are built right inside the chip. 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. Serial commands may comprise of a single byte or multiple bytes of data depending on the command type. The serial platform allows users to develop their application using their favourite micro-controller and software development tools. In short, it offers one of the most flexible Graphics controllers available that will run ‘out of the box’.

All of the data and control signals are provided by the chip to interface directly to the display. Simply choose your display and interface it to the GOLDELOX-SGC beside your host controller on your application board. This offers enormous advantage to the  designer in development time and cost saving and takes away all of the burden of low level design. The GOLDELOX-SGC can be considered to be another Black Box which the designer knows will work and therefore more design emphasis can be put into the final User Interface and overall high level design criteria.

NOTE: The architecture of the base GOLDELOX device is such that it can be reconfigured either as the GOLDELOX-SGC or the GOLDELOX-GFX2. This chip-level configuration is easily achieved by re-programming the chip with the appropriate PmmC file.

DISP Config File: The GOLDELOX-SGC must be configured to work with a target display. The DISP config file contains information for the display hardware registers, embedded fonts, splash screen settings, screen saver, etc. Download and import this sample file into the DISP-Software-Tool and modify the parameters to suit the target display.

DISP Software Tool: DISP is a free software tool used to:
     - Configure the GOLDELOX-SGC chip to work with a specific display.
     - Modify the way the chip initially sets up the display, e.g. screen saver
     - Construct the splash screens.
     - Replace or modify the embedded fonts.

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-SGC. The converted font set can then be exported into the DISP-Tool utility which can then be programmed into the GOLDELOX-SGC on-chip flash memory.

FAT-Controller Software Tool: This is a free software tool to test all of the functionality of the GOLDELOX-SGC device. It is useful in learning about how to communicate with the chip and it can also simulate most of the operation of the device. It can also assist in the creation of simple scripts, either simulating the execution of those scripts and/or downloading them into a memory card for execution on the display.

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-SGC. The host simply sends serial commands to the GOLDELOX-SGC to display the multimedia objects.
