Error while creating pin files

[alexarroyoduque]

Hi, I'm using a raspberry pi.

I have been experimenting with the CylonJS library following the documentation example. However when I run the script I get the following error.

Can anybody help me?

  },

  devices: {
    led: { driver: 'led', pin: 18 }
  },

  work: function(my) {
    every((1).second(), my.led.toggle);
  }
}).start();

I have the same problem. Investigating and looking to see if I find the way to solve the problem.

@warlock, @alexarroyoduque, I was having the same issue running a very similar script by simply sshing into our pi and running this script:

'use strict'

const Cylon = require('cylon')

const PIN_NUMBER = 11
let interval = null

Cylon
  .robot({ name: 'TestBot' })
  .connection('raspi', { adaptor: 'raspi' })
  .device('led', { driver: 'led', pin: PIN_NUMBER })
  .on('error', function (error) {
    console.log('got an error!!!!')
    console.error(error)
  })
  .on('ready', function(bot) {
    interval = setInterval(function() {
      console.log(`Toggling LED at pin: ${PIN_NUMBER}`)
      bot.led.toggle(function () {
        console.log('Toggled LED')
      })
    }, 1000);
  });

Cylon.start();

process.on('SIGTERM', function () {
  console.log('SIGTERM event caught')
  if (interval) {
    clearInterval(interval)
  }
  Cylon.halt(function () {
    console.log('Halted Cylon')
  })
})

Was only able to get passed the error by running the script using sudo:

sudo node index.js

The project has been abandoned. It's sad because Cylon is the best known system of this type for Nodejs. I will try to find time to understand how it works and maybe I will write a fork or an alternative.

Hi @warlock , @alexarroyoduque and @mymattcarroll,

I know this project was abandoned and this issue quite old, but, were you been able to solve this problem? I'm facing the very same issue, and although is not active this project, it still works fine for some mini-projects.

Thanks in advance!

Regards,
Miguel.
