MMM-Navigate, Issues with KY-040 rotary encoder

[stinkycol]

@sdetweil I am using PM2 in my other build but i haven’t implemented it in this one as i just wanted to confirm the KY040 code worked before moving on to autostarting

[sdetweil]

@stinkycol pm2 has lots of commands

in linux the convention is commands provide help two ways

1. using the --help param
2. providing a manual page, seen with man program_name

pm2 status will show you what is defined and what its state is
you can control individual apps (I have 10 defined on one system)
with the number of the row that matches their name or the actual name (oops I have 3 MagicMirror apps defined in different locations, so I have to use the row number

pm2 stop xx

or if you know what they are you can stop them all
pm2 stop all

you can restart an app too

etc…

@stinkycol i have seen that error on other posts, and it sounds like there are some new tests on setting up the gpio pins.

the code wants 3 pins,
the node_helper code

		console.log('MMM-Navigate, listen on GPIO PINs (BCM): '+self.config.GPIOPins[0]+','+self.config.GPIOPins[1]+','+self.config.GPIOPins[2]);
		const CLK = new Gpio(self.config.GPIOPins[1], 'in', 'both',{debounceTimeout : 0 }); //BCM Pin 20
		const DT = new Gpio(self.config.GPIOPins[0], 'in', 'both',{debounceTimeout : 0 }); //BCM Pin 26
line 38		const SW = new Gpio(self.config.GPIOPins[2], 'in', 'both',{debounceTimeout : 20 }); //BCM Pin 19

the error is on the last, which is the one you added to the boot time config.
I think ‘both’ incorrect for this.

when you used profileswitcher, what module did you use for connecting the encoder? as that module doesn’t have a hardware component

@sdetweil I used MMM-GPIO-Notifications as i was using this on my other build to use simple buttons to swap pages.

On the latest run I still get the errors:

These are the entries in the config.js:

This is the npm output as i move the KY040:

@sdetweil sorry I don’t write understand how you figured that the last one was causing the issue and is this an issue with boot/firmware/config? Did this mean that I should replace the gpio in the MMM-Navigate module on config.js to the sudonyms?

GPIOPins:[DT, CLK, SW]

@stinkycol I looked at the line numbers reported in the stack trace dump that came along w the write error

I do not know what the solution is

[stinkycol]

@sdetweil OK thanks for trying

[sdetweil]

@stinkycol the gpio notifications module does the gpio connection differently
