Python in to the magic mirror.

[paulvanderheijden90]

@sean
Hello Sean,
The problem is not the python project. But I think the buffer is filling up ore something.

At this point all the massages are displayed on the mirror and after 15 min the mirror is freeze.

So im looking in to it.

@sdetweil fixed sorry

[sdetweil]

@paulvanderheijden90 i don’t see the python module

you can add it to the directory and repo temporarily, then remove it later

[sdetweil]

@paulvanderheijden90 so far I don’t see the same crash error…

I did have to make some minor changes…

Module name to match the git repo name
path to a python script
and change the display handling…
rule is ONLY content change location is getDom()…
other routines should store data and call updateDom(0 to signal that there ARE changes to display

I’m gonna let it run for a while…

@sdetweil
hello ! Thank you for your help so far.

The python project is running fine on it selfs.

But wenn I use it with the magic mirror the buffer of the magic mirror is filling. And freezes.

the python project is made in combination with a Antenna.
Setup looks like https://nl.oneguyoneblog.com/2016/08/09/p2000-ontvangen-decoderen-raspberry-pi/#comment-488

so you’ll need to have data from the Multimom to get different information to send to the mirror

[sdetweil]

@paulvanderheijden90 I wrote a little hello world python script to send data. All that is working as expected so far

How big is the data buffer your python script sends?

[paulvanderheijden90]

@sdetweil
it is almost 50 char long. Im making a screen movie to let you see what I meen so it will become clear.
Send it you in a couple of minutes

Please see the full movie and notice the fail at 1:41

Very interested in this project… I have a python script to control my thermostat and was wondering how to get port it over…this may give me some answers :)

[sdetweil]

@paulvanderheijden90 i submitted a pull request to your repo. this code runs for hours and hours…
tiny changes from yours…

the biggest is that the module filename is changed to match the name of the project
(but that isn’t why it hung)… I actually don’t know the cause on your side…

please download my code and try it out… let me know

@sdetweil @Sean
Hello Guys Thank you for your vallueed help!

I found out that the spawn function is called every time. so in a couple of minuts the spawn function has called 100 python projects. and this is blocking the raspberry

I changed is to this: and now im going to Import the project of sdetweil in the software. But it is no more blocking.
thank you guys

/// node_helper.js



const spawn = require("child_process").spawn



var NodeHelper = require("node_helper")


var process = spawn("python", ["/home/pi/src/P2000.py"])




module.exports = NodeHelper.create({



  socketNotificationReceived: function(notification, payload) {



    switch(notification) {



      case "GIVE_ME_DATA":


	

        this.job()



        break



    }



  },



  job: function() {

	
    
    process.stdout.on("data", (data)=>{

      console.log(data)

      var result = String.fromCharCode.apply(null, new Uint16Array((data)))

      this.sendSocketNotification("HERE_IS_DATA", result)



    })



  }
