MMM-Swipe - Hand gestures

[mochman]

@BeLuGe So I just tried this myself. When I created the module, I was connected to the pi to test. I just tried using SSH to start the program and got the same error you’re getting. Looks like it’s a issue with running a sudo command over SSH, the workaround I found was to run sudo cp ~/.Xauthority /root/ then run DISPLAY=:0 sudo npm start. The problem with this is that everytime you restart your mirror you will need to run the copy command again.

@Mitchfarino You don’t need a breadboard. I just used one to test out my configuration. You can hook it up directly to the pi using those wires you have already connected. When I tested out my setup, I used these pins.

echoLeftPin: 24,       
triggerLeftPin: 23,     
echoRightPin: 26,      
triggerRightPin: 25,   

Remember that those are the GPIO #'s and not the physical pin #.

@mochman I have vcc, trig, echo and gnd on my sensor - how do they map to the config you have posted?

[mochman]

@Mitchfarino

Your left sensor

Vcc goes to pin #2
Gnd goes to pin #6
Trig goes to physical pin #26 (Which is labeled GPIO 23)
Echo goes to physical pin #18 (Which is labeled GPIO 24)

Your right sensor

Vcc goes to pin #4
Gnd goes to pin #9
Trig goes to physical pin #22 (Which is labeled GPIO 25)
Echo goes to physical pin #37 (Which is labeled GPIO 26)

You need both sensors if you want to detect movement.

@mochman OK, I’m an idiot!

I only have one sensor! Ha

Thanks very much for your help, I’m gonna get one ordered then get back on it.

Sorry for the daft questions

[mochman]

No worries. Yeah the sensor looks like it has 2 detectors on it. I’m pretty sure one is the speaker and the other is the microphone detector.

@mochman when I use your workaround i get the following errormessage and a whitescreen:

MagicMirror will not quit, but it might be a good idea to check why this happened. Maybe no internet connection?

Can you make another config.js file with just the MMM-Swipe module in there? I don’t know what the:
WARNING! Could not load config file. Starting with default configuration. Error found: Error: Module version mismatch. Expected 49, got 48. means.

[BeLuGe]

@mochman I change the config file to default and add your Module. The same errormessage.

[mochman]

@BeLuGe Try running rm -rf node_modules/ inside the MMM-Swipe folder then running npm install again.

[BeLuGe]

@mochman I have delete the directory and install the packages with npm install
And I have reinstall the complete Raspberry and install only your module.
The error is still there
