        Q03. Can i use FAT formatting on the uSD card in a GOLDELOX-GFX2 based display module?

        Ans. No, you can't use FAT formatting. It's not supported by the GOLDELOX-GFX2 processor, you would have to use the card in raw format.

            Q05. Can I use custom displays with the GOLDELOX-GFX2 processor?

            Ans. Yes, you can use displays that provide 8bit 80-Series CPU interface. You would need to use the generic GOLDELOX-GFX2 PmmC and do the initialization in the 4DGL code.

            Note: Ideally, contact 4D Systems for a final verdict about a display's ability to be interfaced with the GOLDELOX-GFX2 processor.

                    Q09. Why are there two PmmCs for the uOLED-128-G1(GFX) module?

                    Ans. uOLED-128-G1 module was initially manufactured with UG-2828GDEDF01 display (Driver IC SSD1339). That particular display was discontinued early 2010. Therefore an equivalent display UG-2828GDEDF11 (Driver IC SSD1351) was introduced and is still in production.

                    -uOLED-128-G1GFX-R21.pmmc is for the Display modules with older displays (Display UG-2828GDEDF01, Driver IC: SSD1339)
                    -uOLED-128-G1hGFX-R21.pmmc is for the Display modules with newer displays (Display UG-2828GDEDF11, Driver IC: SSD1351)

                      Q10. How would i know if i have a uOLED-128G1(GFX) or uOLED-128-G1h(GFX)?

                      Ans. uOLED-128-G1 boards with Rev1g and below are with older displays (Display UG-2828GDEDF01, Driver IC SSD1339), while the boards with Rev1h and above are with the newer displays (Display UG-2828GDEDF11, Driver IC SSD1351).

                      Note: Check the back of the board, you should see the board revision something like the one shown in the attached images.

                        Q11. Why are there two PmmCs for the uLCD-144(GFX) module?

                        Ans.The display used on the uLCD-144 initially was with ST7735 Driver IC which is discontinued. It was discontinued by the end of 2010. Therefore an equivalent Driver IC ST7735R is used.

                        uLCD-144GFX-R21.pmmc (Driver IC: ST7735)
                        uLCD-144rGFX-R21.pmmc (Driver IC: ST7735R)

                          Q12. How would i know if i have a u uLCD-144(GFX) or a uLCD-144r(GFX)?

                          Ans. Check the image attached. On the warranty label there is an "R" written in Block letter to specify a uLCD-144r module. The warranty labels are pasted on top of the uSD connectors on the module. Attached files

                            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.

                              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.
