I'm trying to access an i2c device via bonescript and I'm getting an error.
Here's the OS info:
*uname -a*
Linux yoder-debian-bone 4.4.15-ti-r37 #1 SMP Tue Jul 19 17:04:02 UTC 2016
armv7l GNU/Linux
*cat /etc/dogtag *
BeagleBoard.org Debian Image 2016-08-01
Here's the code:
var b = require('bonescript');
var bus = '/dev/i2c-2';
var TMP006 = 0x40;
b.i2cOpen(bus, TMP006);
b.i2cReadByte(bus, onReadByte);
function onReadByte(x) {
if(x.event == 'callback') {
console.log('onReadByte: ' + JSON.stringify(x));
}
}
Here's the error:
/usr/local/lib/node_modules/bonescript/src/iic.js:15
if(m.ports[args.port[0]].path) path = m.ports[args.port[0]].path;
^
TypeError: Cannot read property 'path' of undefined

Here's the plea:
How do I fix this?
Thanks...
