Aria/Fox GPIO

This module provide a simple full asynchronous interface for GPIO management for Acmesystems Aria and FoxBoard products. Visit AcmeSystems official site for more informations about this hardware. This module use a C program to detect interrupts on GPIO, developed by Antonio Galea and modified by me to debounce the inputs.

To create documentation you must install JSDuck and type in your terminal:

$ ./gen_doc.sh

Please visit Yoovant website for more informations.

Usage

If you have a new amazing Acmesystem Aria board or a FoxBoad G20, you can easy manage GPIO using Node.js and this module or the daisy_gpio to manage Daisy board for fast prototyping.

Install the package as usual:

debarm:~# npm install aria_fox_gpio

and write a simple program:

// define the OutGpio class from the aria_fox_gpio module
var Led = require('aria_fox_gpio')({
    model: 'fox',
    debug: true
}).OutGpio;
// create a new Led instance
var led = new Led('D2', 2, function() {
    // use callback to handle the init
    console.log('init callback button #1');
    var isOn = false;
    setInterval(function(){
        isOn = !isOn;
        if (isOn) {
            led.setHigh();
        } else {
            led.setLow();
        }
    }, 500);
});
// attach the init event fired (after the callback) when the led is ready 
led.attach('init', function(event) {
    console.log('init event button #1');
});
// attach the rising event fired when the led is turned on
led.attach('rising', function(event) {
    console.log('led is turned on');
});
// attach the rising event fired when the led is turned off
led.attach('falling', function(event) {
    console.log('led is turned off');
});

Save your file as blinking.js and run in your terminal:

debarm:~# node blinking.js

Your led is blinking.
