      Due to recent issues I have been getting with My 7inch screen and PanelDUE V1 I have ordered a CPLD 7 Inch screen.

      Is there anything I need to do to connect it or is it Plug n Play?

      For sake of clarity the issue I have with the existing screen is that it can sometimes take 3-6 power cycles of the printer for the screen to initialise to the correct display. once it has initialised correctly it is alway fine when it doesn't it is just a mass of Greyscale lines.

        Display arrived and connecting it to my PanelDue V1.0 with FW V1.20rc1 on it and the display doesn't initialise.

        Any advise do I need to upgrade to a V3.0 board?

          Did you install the CPLD build of the firmware?

          I didn't write the CPLD display support, i accepted a pull request from another developer. So I don't know much about it.

              Thank you David for the Firmware file and the display is definitely crisper with the CPLD Panel although it hasn't cured my issue when it is on the printer and I suspect it is down to the 5V rail not having the guts to drive it (I have prob a 1.5 mar long loom) so I will re-wire it using some slightly heavier gauge wire for the Power lines for it and see if that makes any difference.

              Failing that I can always feed it with an external 5V USB Cable till it has booted up fully

              Thanks Again
