MMM-Navigate, Navigation inside MagicMirror with Rotary Encoder

@Eisblume
I found the line in node_helper.js, its line 35

const C = new Gpio(self.config.GPIOPins[2], 'in', 'both',{debounceTimeout : 20 }); //BCM Pin 19

Here you can try to increase/reduce the debounceTimeout between 10 and 50 (in steps of 10) and see if there is a difference for your “pressed” problem.

@AxLed
I tried every very with different press speed. It doesn’t work. No press Signal will be sent :-(

I don´t understand why cw and cww works fine, but not the press - Button?

Edit:
I test the Rotary with this: https://github.com/martinohanlon/KY040
Here the press button works fine.

pi@raspberrypi:~/EncoderTest/KY040/examples $ python python3.py
turned - 0
turned - 0
turned - 1
turned - 1
button pressed

@Eisblume
Please post your config and make sure your private keys are x-ed. So i can try to copy your setup to my test pi and maybe find out whats the reason. That your rotary encoder generally works is good to know.

Ok, thanks @AxLed !!

@Eisblume
I tested wih modules of your config.

My testconfiguration:

Raspberry Pi 1
MagicMirror v2.7.1
npm v6.8.0
node v8.9.0
no electron (as i dont run/installable on Pi 1), i run node serveronly
display: Webbrowser

My rotary encoder works as follows:

Seite blättern (press works and gives a red frame an a lock sign, cw an ccw dont work, as MMM-Pages isnt part of your config)
News (mehr/weniger Details) (press works and gives a red frame an a lock sign, cw an ccw works)
Test notification (press works, no cw or ccw functionality by design)
News - mehr Details (press works, no cw or ccw functionality by design)
News - weniger Details (press works, no cw or ccw functionality by design)
Neustart MagicMirror (PM2) (dont work in my testconfiguration, as i dont use PM on RPI1)
Neustart (press works, there is a pop up notification to press twice for reeboot, requires MMM-Remote-Control)
Herunterfahren (press works, there is a pop up notification to press twice for shutdown, requires MMM-Remote-Control)

Two ideas:

wrong cabeling, here are the 3 pins for CW, CW and PRESS of your config.js (GPIOPins: [26,20,19])
messed up setup, try to save your config and reinstall raspian an MM

Thank you so much for your help. But It still doesn’t work.

The cabeling is correct I checked it many times ;-)

The crazy thing is, when I remove ground, the press button works, but not the cw and cww.

I think, I will try a clean reinstall on my RPi3.

Eisblume · May 23, 2019, 12:12 PM

@AxLed
Also after clean install with nothing more, the default modules and MMM-Navigate and MMM-Remote-Controll it doesn’t work.

Here you can see: https://youtu.be/G2eRoPxRPjU

Only when I remove ground, the press action works. But then, the cw and cww doesn’t work…

AxLed · May 23, 2019, 7:20 PM

@Eisblume
Thanks for your reply, i tested at my pi with disconnected ground cable, but there is no press, cw or ccw working at all.
My last ideas:

can you messure your 5 cables if maybe one is interrupted
maybe there are two versions of KY-040 on the marked, i have this one Amazon
is your second rotary encoder shows same symptoms?
did you connect + of rotary encoder to 5V once (which would be wrong and maybe damaged your GPIO PINs/chip)?

@AxLed
Do not think that I am lying ;-), but it works fine, when I start MagicMirror and after that I start the python - script from here https://github.com/martinohanlon/KY040.

cw, cww and press works absolutely fine.

It is very strange.

Eisblume · May 24, 2019, 7:01 AM

@AxLed
Ok, i fix it now for me.

I know, it is a dirty code, but don’t found another solution :dizzy_face:

I attached the KY040 python script in the node_helper.js. Then everything works fine.

//node_helper.js
