MMM-Navigate, Navigation inside MagicMirror with Rotary Encoder

Eisblume

@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…

@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)?

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.

@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

 //Debugging
 //tail -f ~/.pm2/logs/mm-out-0.log
 //tail -f ~/.pm2/logs/mm-error-0.log 

const Gpio = require('onoff').Gpio;
...
const spawn = require("child_process").spawn;
//Variables
...
  start: function() {
		var self = this;
		this.loaded = false;
		var process = spawn("python", ["/home/pi/Downloads/KY040/examples/python3.py"]);
	},
	
...
});

No Problem, i am glad it works for you now, so you also did your first coding experiance.

AxLED

Eisblume

@AxLed
Yes very interesting experiences :-) !

Could you explain my how to start “Tagesschau in 100 Sekunden” in MMM-Navigate ??

AxLed

@Eisblume
You need two things:

first: a modules which is able to stream 100Sec Tagesschau, i made a fork see MMM-Podcast2
second: the right config (i posting only the relevant part)

....
{
			module: 'MMM-Podcast2',
			config: {
				// See 'Configuration options' for more information.
				omxargs: ' --win 0,0,1920,1080  -o both '
			}
		},
{
			module: "MMM-Navigate",
			header: "Navigation",
			position: "top_right",
			config: {
					Alias: [
						'Tagesschau 100 Sekunden',
						'Herunterfahren'
					],
					Action: [
						{notification:'BUTTON_PRESSED',payload:''},
						{notification: "REMOTE_ACTION", payload: {action: "SHUTDOWN"}}
					],
					GPIOPins: [26,20,19]//rotary cw, rotary ccw, rotary press (BCM Numbering)
					},
		},
...

@AxLed said in MMM-Navigate, Navigation inside MagicMirror with Rotary Encoder:

{notification:‘BUTTON_PRESSED’,payload:‘’},

Thanks. Works perfect !!!

Hello @AxLed ,

Two things:

First

I have the same issue like @Eisblume :

The click doesnt work.
When i then start a sample code to test the rotary encoder (from like here), the click works in the sample code.
If i start the Magic Mirror after that again, then the click works there too.

Maybe there is a missing initialization of the rotary encoder in your code?

Second

Is there a possibility to get more config possibilities?
Like starting the module hidden or shortening the time of the hiding process?

Thanks in advance :)

AxLed

@keineAhnung123,

to your first issue:

is only click not working or is rotation also not working?
Because rotation and click (Button press) uses the same library (onOff).
on which pin is click connected, as the pi GPIO Pins have different features?
what versions you are using (pi, OS, MM-Version)?

To your second issue.

MMM-Navigate uses the MM notification system, so you can do almost everything you want. What are you trying to to, maybe i can give you a sample for your config.js
for shortening time of hidding see MM Docs -> search for hide, there is a parameter for speed.

Regards
