problem running Maxbotix demo

[jBachalo]

This is my exact code. When I run I can see only the first trace. Is there a method or property of my.maxbotix \ that might help in debugging potential hardware, wiring issues?

var Cylon = require('cylon');
    Cylon.robot({
       connections: {
          edison: { adaptor: 'intel-iot' }
    },

devices: {
    maxbotix: { driver: 'maxbotix', pin:'1' }
 },    
work: function (my) {
    every((1).seconds(), function () {
        console.log('0 ASSERT  FIRST TRACE 1 second interval my.maxbotix' + my.maxbotix);

        my.maxbotix.range(function (data) {
            console.log("1 ASSERT 2ND TRACE range: " + data);
         });
      });
  }
}).start();

@jBachalo I see the issue, what is happening is that there is a disconnect (outdated) docs and examples between how this used to work and how it works now.

Basically the my.maxbotix.range() only returns a value but does not receives any params, so what you have should work if you do it like this:

var Cylon = require('cylon');
    Cylon.robot({
       connections: {
          edison: { adaptor: 'intel-iot' }
    },

devices: {
    maxbotix: { driver: 'maxbotix', pin:'1' }
 },    
work: function (my) {
    var range = 0;
    every((1).seconds(), function () {
        range = my.maxbotix.range();
        console.log('Maxbotix range: ', range);
    });
  }
}).start();

You can also use a similar approach that returns a new value every time there is a read from the maxbotix by doing something like this:

var Cylon = require('cylon');

Cylon.robot({
  connections: {
    edison: { adaptor: 'intel-iot' }
  },

  devices: {
    maxbotix: { driver: 'maxbotix', pin:'1' }
  },    
  work: function (my) {
    my.maxbotix.on('range', function(err, range) {
      console.log('Maxbotix range: ', range);
    });

    my.maxbotix.on('rangeCm', function(err, range) { 
      console.log('Maxbotix range in cm: ', range);
    });
  }
}).start();

That is a different approach that provides values as fast as the board can read them from the analog input.

Thats it!! thanks

Cool!, nice to hear it is working now. We are correcting and updating the docs shortly, you can go ahead and close this issue.
