Arduino Mega COM / NAV Panels - character display

[burschid1]

Hi Guys,
I would like to build a radio / nav panel for a cessna.
Is there any guidance on which connections I need to use on the Arduino mega and the character display (MAX7219)?

Have a nice day!
Chris

HI,
a google search on - air manager max7219
First result - https://siminnovations.com/wiki/index.p ... isplay_add

Scroll down page to the two entries for 7219.
Enjoy.

Thank you very much!
I am still a beginner and learn more and more.

The display is connected correctly.
I am using MSFS 2020 and would like to display COM 1 / 2 and NAV 1 / 2.
Unfortunately I have only found an example for X-Plane.

Can someone help me to rewrite the script to MSFS?

Example for X-Plane:

Thanky Guys!!!!

There's already a hardware function for this. Just click +Hardware in the home tab, search for radio or something, configure what you want to display and you're done.

Just for info @Ralph, I've not found any Hardware Instrument in the available list, which would fit this need

You're right, it wasn't there. What I think happened, is that back when I made this, we still thought that there were issues with the software for the MAX displays, which turned out to be a hardware issue. So I didn't upload it, waiting for a fix, which never came, because there wasn't anything to fix

I've uploaded it just now, and it is called COM/NAV stack based on MAX7219.

Thanks again @Ralph, just checked it's there :

Thank you very much for the good work and support! It's works very good!!!!
I still have one question. Currently I have only one display connected (DIN = D4, CLK=D5 , Load=D6)

Where must the second (standby) display be connected?

Sorry for the simple questions but it's the first time I work with Arduino.

Thanks and Bye
Chris

Hi Chris, just daisy chain the units, you should have the inputs on the left of the pcb and the outputs on the right. Just wire the right side of the first board to the left side of the second board. The only pin name change is Din is on the left of the board and Dout on the right, dout goes to din. Load and clock are common. Just wire them pins on the right of one board to pins on the left of the next board

Thank you very much!!!!
It sounds very easy and I will try it.


Thank you all for the help and AirManger is a very good Software!

Bye
