Hello, dear simmers. i want to create DIY CDU. how can i display cdu info to (connected to arduino) display? Ik, that i can buy from ali default mini-4 inch display, which i can connect to pc as a default monitor through VGA/HDMI cable, but it cost a lot more, than a default display for arduino and i dont want to use another cable to connect it to my GPU. If u know, how to display any info from CDU to arduino, help me :)) thank you!

You plug it in to your PC as a monitor then use whatever methods are available in your sim to pop the display out to a separate window and then drag it over to the display
the arduino isn't involved in the display at all
that 4" display is what everyone uses for this
The Atmega328p doesn’t have a built in lcd controller so if you don’t want a hdmi-based screen you need to get an lcd with an controller that supports Atmega328p. I used an hdmi-based screen on mine and it works great!
I'll add that I would, honestly, not spend time doing a DIY CDU (having done one myself!). I would just buy a winwing CDU.
Agree! Winwing is so much better. If mine fails I will probably not fix it and just get the winwing…
yeah, ik. then, i cant connect it through mobiflight if i will use some lcd controller?
and one question, if i will use sketch from arduino ide, can i connect my board to mobiflight w/o updating firmware?
upd: thank u for the answer. i checeked ali. ig, i will buy default display w/ hdmi.
have a good flights!
You only have two options. Use a joystick emulation sketch on a Leonardo or Pro Micro board, or use one of the supported boards and run the Mobiflight firmware.
None will have the capacity to generate the screen for a CDU.
thank u. i will use arduino w/ mobiflight only for buttons.
and last question - which display did u use for this? can i buy some displays for raspberry pi and just connect them through hdmi or vga to my GPU and use it as second monitor?
The issue is that if you do not use the display popout option, then you have to develop an app that will essentially replicate the functionality of the CDU to write the same information to an independent screen.
this is overkill. ig, use some hdmi display is easier, than developing an app

Hi man, that is exactly what I did.
Used a dedicated monitor built in a printed case and dedicated PCB designed on my own. I can share you more details in private chat 😉
First I used the FergoCDU tool that I modified, and at the end I used dedicated script issued bu PMDG that I also modified to fit my screen size
can you share more info about this dedicated script?
This is what PMDG delivers in the SDK. It is a bit tricky to build the link with Simconnect (MSFS SDK) but doable.
I will share it to you in a few days (currently at Spa for the wec race)
