Again -- MMM-Navigate can't get installed.

crowimu

@sdetweil Yes, sure. I assume there must have been a change in the GPIO handling, but have not figured out where. :(

@crowimu
Only thing that comes in my mind that you have either put cable on wrong GPIO or cable is broken.

As per default you have either to use GPIOPins: [26,20,19]//rotary cw, rotary ccw, rotary press (BCM Numbering - marked yellow in the above picture) or (if occupied) enter the correct BCM (!) numbers in config of module.

If this is all correct, module should work.

@crowimu Last thought - after some googeling…
Axled (the author has a thread about his module.
In one of his posting he stated
“rotation and click (Button press) uses the same library (onOff).”.

“node_modules/onoff/onoff” is part of your error-listing.

So I can imagine you need this onoff -library to read the GPIO-output.
Further research on this let me assume that onoff in some kind is associated to node.js (@sdetweil for sure knows more on this than me…).

At least one onoff library in this context is this one - but I’m not sure if this is the right one.
May you give it a try…

edit: I’ve just checked - on my own mirror there is NO onoff directory in “MagicMirror/node_modules/”

Good luck.

@crowimu Found in completely different context another hint to onoff - also related to GPIO (in concrete a GPIO related implemetation of a rotary decoder).
There was a suggestion

npm install --save onoff@6.0.0

I currently only „assume“ that @6.0.0 is the version - cause the cited post is from 2021 there could be a new version.
A quick google delivers this page and this one stated

npm install onoff

Will do the trick…

Good luck.
Ralf

@rkorell Thank you and all others for the hints, however up to now I did not manage to get the ‘onoff’ and the MMM-Navigate module workingon my system.
I have recompiled onoff, installed it globally, changed the node version.
Nothing helped yet :(

I have started to create a simple module for my needs to control some fuctions with a rotary encoder,
https://github.com/crowimu/MMM-RotaryNav
It’s early stage, please wish me luck. :)

@crowimu
very unfortunate!

cross the fingers & good luck for you…

@crowimu - Just a quick question: Have you considered to use a newer version of a Pi? A 4B or even 5?
Pi2 is somewhat old - may there is a kind of a root cause?

Regards,
Ralf

@rkorell Hi Ralf,
I think the quadcore RPi2 is quite sufficient for a Magic Mirror, but I’ve also tested it on a RPi3 with the same results.
I don’t like the power consumption of RPi4 and 5 and I also don’t like to add cooling fans to an SBC.
So up to now I have always used RPi Zero / Zero2 / RPi 1/2 and 3 smoothly for my projects. :)

@rkorell finally I got it solved :)

The issue is really the GPIO numbering, I found this SO thread:
https://stackoverflow.com/questions/78173749/use-raspberry-pi-4-gpio-with-node-js
It is also valid for Pi3 and Pi2

cat /sys/kernel/debug/gpio

gpiochip0: GPIOs 512-565, parent: platform/3f200000.gpio, pinctrl-bcm2835:

 gpio-531 (GPIO19              )
 gpio-532 (GPIO20              )
 gpio-533 (GPIO21              )
 gpio-534 (GPIO22              |sysfs               ) in  hi IRQ

 gpio-537 (GPIO25              )
 gpio-538 (GPIO26              )
 gpio-539 (GPIO27              |sysfs               ) in  hi IRQ

I needed to set up the numbers according to the output
e.g. Pin27 is 539 in the MMM-Navigate config.
Now everything works so far as expected, thank you all for your help!

@crowimu COOL!
congratulations!

For me the “confusing” part was the fact that INSTALL doesn’t work…
Installing should NOT check GPIO pinouts …

Really great that you worked this out!

Warmest regards,
Ralf
