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"]);
	},
	
...
});

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

@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
