    Q26. What Colours are available for use with the Graphics functions?

    Ans. An assortment of colours are available that range from 0x0000 to 0xFFFF. A full listing of these colours can be found in the 4DGL_16bitColours.fnc file, which is located in the installed directory of the 4DWorkshop. This file can be accessed through the Workshop by firstly inheritting the file as so;

    #inherit "4DGL_16bitColours.fnc"
    Right click on the file and click 'Open file at Cursor'. This will display all possible colours. The same technique can be used on other inherit files to view their details

    Q23. Can I power the GOLDELOX-GFX2 based display modules through 3.3V?

    Ans. All of our GOLDELOX-GFX2 based display modules have on board protection diodes and 3.3V regulators, they have forward voltage drops. Therefore you need to provide 5V to the display modules.

    Q18. I am having problems communicating with the uSD card?

    Ans. Make sure your uSD card supports SPI interface, that is how the on board GOLDELOX-GFX2 processor connects to the uSD card. There are some duplicate cards in the market which fail to work with SPI with accuracy. No specific brands, it is just that they are duplicates of the popular uSD brands.

    Q17. Is it true that gfx_Trianglefilled() command slower then drawing other filled shapes?

    Ans. Yes, GFX_Trianglefilled() is slower than drawing other filled shapes because there is no display internal commands that allow fast filling in the triangle.

    Q16. Why does the contrast command not work with the uLCD-144(GFX) module?

    Ans. The LCD screens do not support contrast settings because of their design. You cannot change the contrast on an LCD, though you can turn the display On or Off.

    Q14. Can i upload the PmmC file or a 4DGL program using my own controller?

    Ans. No, you need to use the Windows based software tool to load the PmmC/4DGL file to the module. It cannot be done through any other controller.

    Q13. Do I need to buy a USB to Serial converter with a GFX configured module?

    Ans. Yes, You need to buy a USB to Serial converter with a GFX module.

    -It allows you to update the PmmC file in case an upgraded GFX PmmC file is released.
    -It allows you to download the 4DGL program to the module.
    -It allows you to change the configuration from GFX to SGC (or vice versa) by loading appropriate (module specific) PmmC file.

    Note: We strongly recommend to buy one of our USB to Serial Converter because they provide Reset Signal which is needed as part of the PmmC programming protocol. There are third party USB to Serial Converters available but they do not provide Reset Signal which is where users get stuck trying to load the PmmC.
