MobiFlight Community Support

I have KY-40 encoder and would like to connect to Arduino MEGA, refer to some instructions from web, it can be connected to any pins of Arduino Mega. I tried several times but it can not function at all. Although I have followed the instruction from MobiFlight Youtube but the result is the same. Please assist me and thank you..

Best regards,

Hi.

I think you mean something like this.... http://i.ebayimg.com/images/g/ZvoAAOxyTMdTLACV/s-l300.jpg

These Encoders are mounted on a PCB and got a special circuit witch shared GRD and uses 5V too.

This is not need with mobiflight ( and maby not useable ... I can´t get run this Encoders in past)

I will recommend you "normal" Encoders like the cheap ones from ALP ... https://www.reichelt.de/?ARTICLE=73923&PROVID=2788&wt_mc=amc141526782519998&gclid=CKOZ4e3n0NECFVG6GwodfrAJgA

You can buy another manifactor, too. Important is only that these Encoders NOT mounted on a PCB and NOT wired in a special logic for maby an Arduino Kit.
Mobiflight needs Always 2 Data Pins and a GRD Pin on the Encoder ( And another Data and GRD Pin if you want a additional push button )

Hope this helps.

Good Luck !

Hi all

At this moment I have an encoder just like that working with mobiflight, and, for now, it has been working fine (I use it for QNH with Jeehell FMGS).

Check the wiring:

GND --> To GND in arduino
BCLK --> To a "random" pin you want to use in arduino
DT --> To a "random" pin you want to use in arduino
SW --> To a "random" pin you want to use in arduino (this is for the switch)
5V --> To 5v pin in arduino (I tried to use it without this connection, and it does not work)

Once this is done, configure the device and input

Finally, try if it works. If it doesn,t recheck wiring and enable debug logging in order to see if Mobiflight recognizes the inputs.

Best regards!

I'm using the encoder aswell and it is working fine. If I don't connect 5v than the encoder inreases the value no matter which direction i go. So make sure you connect 5V.

Nice to hear !

Then sorry for wrong information.... I Try this in my early phase with poor experience about the technic. Maby i did another misstake, but i not be able to get these Encoders run this time.

But finaly i recommend the alps again.... Cheaper and 1 cable less. And if you want to drill a hole through the encoder to build a concentric rotary encoder these Metal Stuff is bad, and you demage the PCB. Then the simply plastic encoders are much better !

Good Luck !

Dear colleagues,

Thanks lot for your advise, I will try a.s.a.p and give you the result. Have a nice weekend..

pizman82 exactly what i'm doing. I had these laying around and i used them for testing purpose. I ordered some plastic ones so i can drill a hole and build dual concentric rotary encoders for my radios and GPS . I didn't get them yet, let's see how it goes. Here some pictures from my radio i want to build for my Cessna 172.

Nice Work.

Hope you got good machines at home.

My first try for this DIY Rotary switches , was with real poor tools..... With a hand Driller it was nearly not posible to get the hole in the middle... ( kill 3 Encoders while testing )
BUT
If you learn it and use a professional drilller or a milling machine this get better and better.

At last one tip to prevent you of going insane ... Just have always a look for the (realy) Small Metal Balls inside the Rotary Switches.... These " bitc**es hurt you and you spent 4 houres per day to search for them below youre desk.

Good Luck !

I did as instructed, the signal on arduino bib when encoder is turned, but the display remain unmove. Any suggestion? I follow the instruction on seeting as Sebastian describe on youtube..

I think we need some more info in order to help.

What aircraft are you using? Manufacturer aircraft (A2A, PMDG, Aerosoft..) or FSX default aircraft??

is it connected properly to FSUIP, etc?

Oow I forget to inform you. I am using pmdg 737..

Sorry for that and thank you

HI

I am sorry to say I have never used PMDG so I couldnt help you much more.

Anyway, It´s understood you need to look for the correct eventID in Mobiflight, and set the value you want to send.

Good Luck!

Dear Herly.

I use PMDG and can help you !
But i don´t know where the problem is.... Do you got Hardware Problems alredy with youre encoder ? (The others here told that it can work in Mobiflight, but you have to wire the 5v+ additional to Arduino.
OR
Do youre switch work and you only got problem to config it for a PMDG Action.

Please test out if you encoder workes correct with maby a standard cessna function.
When youre encoder runs fine then i can help you to set every PMDG function you like. got Lists and configs for most of functions.

Dear colleagues,

I solved already my problem, it was caused by mis coding on parameter..and the pin coding input. Thanks for all and have a nice weekend..

Just would like to ask a question why the encoder, when I turn right or left more fast why the display moving slow? Is there any improvement how to fix it?
Thanks lot..
