ODROID-IO

ODROID-IO is a Johnny-Five I/O Plugin for Odroid C2
IO Plugin for
Johnny-Five. It extends
board-io to provide Linux
implementations for the following features that IO Plugins can support:

* Digital IO
* Implementation based on the GPIO sysfs interface using onoff
* I2C
* Implementation based on the /dev interface using i2c-bus

Installation

``
npm install odroid-io
`

Johnny-Five Features Supported

The Johnny-Five features supported by a platform are summarized in tables on
the Platform Support page. The
features supported by Linux-IO shown in the following table:

Feature | Support
:--- | :---
Analog Read | yes
Digital Read | yes
Digital Write | yes
PWM | no
Servo | no
I2C | yes
One Wire | no
Stepper | no
Serial/UART | no
DAC | no
Ping | no

Usage

Here's a minimalistic IO Plugin for the Raspberry Pi called
TinyRaspberryPiIO
that allows digital IO on GPIO4 and GPIO17 and I2C serial bus access on I2C
bus 1. The built-in LED can also be used.

`js
'use strict';

var five = require('johnny-five');
var OdroidIO = require('./odroid-io');

var board = new five.Board({
io: new OdroidIO()
});

board.on('ready', function() {
console.log('Board Ready');
var adc = new five.Pin({
pin: 'A0',
type: 'analog',
});
adc.read(function(err, val) {
if (err) {
console.log('Error reading ADC: ', err);
} else {
console.log('ADC Value: ' + val);
}
});
});

`

If an ADXL345 accelerometer is connected to I2C bus 1, the following
program
will print information provided by accelerometer.

`js
var five = require('johnny-five');
var OdroidIO = require('odroid-io');

var board = new five.Board({
io: new OdroidIO()
});

board.on('ready', function() {
var accelerometer = new five.Accelerometer({
controller: "ADXL345"
});

accelerometer.on("change", function() {
console.log("accelerometer");
console.log(" x : ", this.x);
console.log(" y : ", this.y);
console.log(" z : ", this.z);
console.log(" pitch : ", this.pitch);
console.log(" roll : ", this.roll);
console.log(" acceleration : ", this.acceleration);
console.log(" inclination : ", this.inclination);
console.log(" orientation : ", this.orientation);
console.log("--------------------------------------");
});
});
