PanelDue designations

What is the difference between 7, 7i, and 7c?

[dc42]

@Weevil 7 is for a 7" display with SSD1963 controller used with the separate PanelDue controller board. 7C is for a 7" display with a CPLD controller, used with the same PanelDue board. 7i is for the Integrated version, where the PanelDue electronics are on the same PCB as the display.

@dc42 Okay, thanks for clarifying. I wasn't sure which firmware update to use.

CPLD ? Is there a schematic available for this somewhere (super interested to see what you used CPLD for on paneldue) ? Thanks

@arhi there is or was a 7" display that used a CPLD chip instead of a conventional display controller. Here's an old listing for it: https://de.aliexpress.com/item/32640600970.html?gatewayAdapt=glo2deu.

Interesting This was designed by you/duet or was some off the market display? Never seen one of those, thanks for the info

@arhi its an option for a display controller thats on the market. These chips sit between the PanelDue or other controller and the LCD screen itself.

cool, so duet has nothing to do with that design it's just a type of LCD .. clear

(I'm rather inexperienced with all the cpld/fpga stuff .. I learned it and do use them in my projects from time to time but even after years I'd not call myself even a junior in that field due to really low number of projects I used them in ... so wherever I see interesting application of them I try to get as much data as I can so I learn / gain some new ideas)
