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

@crowimu ok, now i dont know. if pi5 it would be new way for gpio

but pi2 i dont know, module author would gave to help

@crowimu
I‘m not using this module and I do not know which of GPIO‘s you are using for your rotary encoder -
In the module‘s description the author mentioned an eventually necessary modification for some of the PI‘s:

On some Raspberry Pis it is neccesary to put the following line to /boot/config.txt for the GPIO where "rotary press (SW)" is connected:

gpio=19=ip,pu

Background: Sets your GPIO 19 as input (ip) and pull up (pu) Change the entry according to the GPIO pin you use.

Have you double checked this?
Your error-listing shows „invalid argument , write“ in some context to GPIO…
May there is a topic for further investigation….

Good luck!

Ralf

@rkorell said in Again -- MMM-Navigate can't get installed.:

gpio=19=ip,pu

Thanks for your help, , but it did not solve the error.
I still get:

@crowimu and you rebooted?

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.

Screenshot 2025-03-01 195116.png

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…
