- Hey Guys!
I hope you are all having a fantabulous day! Today I will show you how to connect a 7 segment display to FSX using a fantastic software called MobiFlight
7 Segment Displays are very useful in Flight Simulation, you can assign them to COM 1 COM 2, Time, ADF, Autopilot and many more!

Great video! Very helpful!
Thank You! I am glad this helped!
Great vid, but my fave part is always the opening theme song. Thumbs way up!
Same here! :) Thanks for watching
cool job, awesome project, by 👋👋👋Brazil !
Thank you!
Thanks this was very helpfull😁
Oh good! I am glad this helped!💥🌟👍
Captain Bob Hey how many segment display can I connect to one Arduino mega?, if you know🤔
@@zz-mt5zf
Theoretically you could use up to 20 on one board (as there are about 60 usable pins) but the USB power would likely not be sufficient. MobiFlight officially limits 4 displays per MobiFlight Arduino (5th question: www.mobiflight.com/en/documentation/faq.html )
There are only (3) 5 Volt Pins, so you would have to use a breadboard for more (There are also 3 ground pins, so a breadboard, or similar solution is needed anyways.) 😃
You can achieve more by wiring displays together. I will show this in a future video 😎
MobiFlight supports up to (8) 8 digit - 7 segment displays daisy chained together so the maximum is up to 32.
(I typically use 3 displays per arduino, and daisy chain them 3 long at most.)
Great Question! 👍✈⭐🌟
Captain Bob Yeah thanks for the super great information, I was thinking about 6 of these 7 segment display to connect to the Arduino mega😆😁
You are welcome! Remember that you can use switches as well as the displays, as you still have about 40 pins. Switches don't draw power :)
Awesome!
Thank you! There was a solid 15 minutes of "yay me I got it to work" dancing! 🤣🤣
😂
Thank you for this very youseful tutorial :)
You are welcome! :)
Hi Captain Bob!
First of all congratulations for you work! You pushed me to make my own panel switch and autopilot module, and i dont understand to much about eletronics :b
Everything is going great exept the 7 segments displays.
I just bought two of them with 4 digits but there is no DC Pin out on this displays.
Can you tell me if i can use them? :s
thank so much :D
Hello! Could you send a link to the 7 segment displays? I'm not sure which ones you are talking about.
Have a great day Fillipe! :D
Hi @@CaptainBobSim :D
I already found the issue.
Apparently the mobiflight only supports 7 segments displays with max7219 chips!
It took me sometime to found this information x)
I will start building my humble flight box! Lets see if everything goes right! Finger crossed ahahaha
Keep doing what you do ;D
Hi Captain, for the max7219 (8 digits): is it possible to split 1 display into 2x3digits (2digits unused)? and then control these two pieces separately? This, for example, to display the Course (3 digits) and ias/mach (3 digits) in 737 with one MAX7219...?
Yep! DIY 737 sim has a great article for this, which I use whenever I need to do anything with wacky MAX7219 displays
It's since been broken: www.737diysim.com/post/737-radio-7-segment-displays
Basically follow the pinout of each module and try to pin it into the 4 digit displays: i.stack.imgur.com/vJzZu.png
The main difference should be the digit pin
Idk if you will See this, but i watched your Videos for a long time and i always wondered, do i really nned like 50 Ardurinos just to make like an Auto pilot segment or is there a Trick to make more segment displays wich all work individually?
You can, just set them to different devices (use different PIN numbers). I think you can hook up 10+ 7 segment displays?
@@CaptainBobSim ok thank you
Do I need an arduino MEGA? Or can I also use an Arduino UNO, because I don't have the mega board. Because this is really cool
You _can_ but it's no longer supported, and has some bugs in the code. Look into the MobiFlight forum for this. I would highly recommend the mega, it's only $15 online so not too big of a deal (compared to other boards)
Hi @captain Bob thanks for sharing. Just a doubt my 6 digits 7 segments don't have the CS pin. Others are OK. In my case, Mobiflight add device with error :( any advice about that ?
Is it a MAX7219 chip? Only these are compatible with MobiFlight currently.
@@CaptainBobSim thanks! Nope it’s a TM1637 :( i choose it because many sizes and color choices… do you recommand a specific model 0.36 Max7219 ? I’m looking for 4 and 6 digits display :)
@@tarikb.2352 Hmm. I don't know if there's a 4 digit display, but if you get the green colored displays, you can remove the pins and extend only 4.
@@CaptainBobSim hi ! I try today with a Max7219 (digits lights ON) but 0 display/light when I upload device setting on Mobiflight :(
Could I also use a LCD display with MobiFlight,I mean a littel screen for the adruino?
Yes! Here is a video, th-cam.com/video/ja0tvTbaEnI/w-d-xo.html
How did you learn to use arduino, I would like to learn. How do you know what wires to plug where?
I learned by looking at Arduino Wiring schematics and looking at the MobiFlight Tutorials. This diagram helps a little: www.circuitstoday.com/wp-content/uploads/2018/02/Arduino-Mega-Pin-Configuration.jpg
The ground pins are negative, and (Sometimes black wire).
The 5v pins are positive, (Sometimes red wire).
The digital pins are where you can plug your switches into, and the positive side of LEDs or other electronics.
The analog pins are typically unusable with MobiFlight.
You can email me if you need more help: CaptainBobSim@gmail.com
Can I use this method and FSUIPC to make it work with FS2020?
Yeah! You can use FS2020's FSUIPC or MobiFlight's built in Events
With release 8.2 much has changed with Mobiflight since you recorded this video. SimConnect and A-Vars have changed how a 7 segment LED can be implemented in Mobiflight. Should be even easier, but not working for me. I am missing something, perhaps others are too. So, asking you to think about the need to update this video (and perhaps others) to using SimConnect instead of FSUIPC.
Hey Steve! MobiFlight just released 9.0! I'm slowly making the change away from FSUIPC (but not 100% appealing to me because X-Plane gets left in the dark). Sebastian from MobiFlight makes release videos with most versions of MobiFlight that should help a little.
I can't promise to update MobiFlight Tutorials to the latest version of MobiFlight, the software advances so quickly, and I don't always enjoy editing my footage down.
Hello my display is working but when I for example press test where u can chose the numbers which represents there are just showing weird led not the one I choose when I run the simulator and press start it just showing random numbers and letters. When I change the numbers in the simulator fs2020 then they are changing as well but to something other weird numbers and letters
It's hard for me to replicate your results. I assume you are talking about the "Transform" window when you are talking about changing the values. In the display tab, the 1-8 numbers are the digits you control, not the numbers on the digit.
This is likely due to some bad 7-Segment displays (sometimes the soldering on them isn't the best). Have you tried this with a different one?
I haven't tried this tutorial with FS2020, so this might be an issue as well 🤔
On the MobiFlight page is the "Output Value" changing to the desired number?
it is possible to use 1 Arduino for multiple indicators or every indicator needs its arduino ??
You can have up to 10 seven segment displays if I recall correctly. You can use the other 60 some pins for other components
can you get 3 digits to the right of the decimal like most glass cockpits have on their G1000's ext? thx
Yes, you'd just activate the 6th digit as well. I believe the output value is in 122.800 format.
@@CaptainBobSim ok, thanks. the logitech panels only allow 3.2 or ###.## so in other words, you can't see what frequency you are on.
Here's a picture with a ###.## radio, they are common. www.aopa.org/-/media/Images/AOPA-Main/News-and-Media/Publications/Pilot-Magazine/2018/1801/1801p_pe_technique/1801p_pe_technique_16x9.jpg?h=675&w=1200&la=en&hash=218AF1F90B8E354B241E3383398DBF80
To my knowledge, most frequencies increase by .025 each step, so only the .## is needed to tell which step it's on. I've seen some exceptions though.
@@CaptainBobSim -- gotcha, i will study more on this topic and thanks kindly.
Hey captain Bob can i use two of these with an arduino nano?
Nano will not work with MobiFlight, but Pro Micro will.
Yes, you can have more than one :)
@@CaptainBobSim thank you so much :) i will buy many pro micros and one 2560 mega.
@@MiguelMadrid-es7ij No problem! Have a nice day!
hi, i'm trying to built a 737 OH, so now i'm trying to connect a switches and led to mega board, but i've a problem when i assign a annunciator for example fuel pump low pressur work fine but when ia turn off ground power and battery switch the led of fuel pump still on, how can i solved this problem?
Hey Simone,
This sounds like a more complicated problem, I might ask this on the forum: www.mobiflight.com/forum.html
@@CaptainBobSim thank for for the answer, I solved the problem, i've another westion (sorry if you took advantage of it) i can connect a lcd display with two rows? is the procedure like the one described in the video?
@@CaptainBobSim thank for answer. I can connect a lcd dipslay with two rows? is the procedure like the one described in the video?
@@TheTribeitaly It is quite similar, look up "MobiFlight LCD tutorial", and you should find a good video on it (it is in spanish)
@@CaptainBobSim thank, you're great
Can i have the program that is uploaded to the arduino for the 7 segment please ??
Negative. I don't have it anymore. My goal is to teach you to know how to make it, not to just to copy/paste- there are many things that can go wrong just copy pasting.
Let me know if you have any questions with this!!
would this work with Xplane11?
I am not sure.
Here is the X-Plane MobiFlight Forum, this might be helpful:
www.mobiflight.com/forum/category/10.html
You would use XPUIPC instead of FSUIPC, as said in this forum.
www.mobiflight.com/forum/topic/525.html
Great question!
Will this also work with FS2020?
studio.th-cam.com/users/video9Ot8EALj99o/comments Heck yeah! Different steps to install mobiflight, but it should work the same :) Happy Landings!
@@CaptainBobSim cheers mate
It's looks easy. But if you don't know which wire you have to put in which port, then you have to spend a lot of time to figure out by watching tutorials en reading forums. You better use this time to save some money and work overtime to buy a complete plug and play device.
This is true, but what's the fun in that! 🙃
Is it working with fs2020 ? Thanks !
Yep! You just need to use MSFS outputs instead of FSUIPC outputs (and select from the list for what you want)
@@CaptainBobSim thanks 👍👍💪
Will this work for Arma3
MobiFlight is not currently compatible with Arma3 using outputs.
my 7 segment display turns on all its lights but nothing else, i tried everything. Can somebody help me?
Have you confirmed its a MAX7219?
Have you triple checked your wiring? Maybe try different wire (not good connection)
Have you tried with a different display? (Sometimes these can be duds)
@@CaptainBobSim yep it's a MAX7219, I checked my wires several times. I have 10 of them, I already tried to change
@@xFrayx Are yours common cathode or common anode?
@@CaptainBobSim everything is settled, after several tests it finally works! the problems were the wires (poor contact) and the number assigned to the display. The only remaining problem is that the comma takes up a whole digit slot.
Sweet! Usually it's a connection problem/dud.
Multiply it by however many digits are after it to get rid of the comma taking a whole digit 👍
