Nodequad

Node library to communicate with AeroQuad open source multirotor platform.

AeroQuad is a fully open source hardware and software platform for multirotor aircraft. More information can be found at http://aeroquad.com.

PLEASE NOTE: Under development. I plan to release at 0.0.9 milestone.

Installing

npm install nodequad

A command line interface is provided to send commands and receive telemetry data. To ensure nodequad is in your path, install it globally with npm:

npm install -g nodequad

Getting Started

• The AeroQuad manual, forum and project: http://aeroquad.com
• Read a quick tutorial on how to use this library: http://jleppert.github.io/nodequad/release/doc/tutorial
• Look at generated library API Documentation at http://jleppert.github.io/nodequad/release/doc/lib
• Browse the examples under the examples directory of the project: http://jleppert.github.io/nodequad/release/doc/examples
• A command line reference is available at http://jleppert.github.io/nodequad/release/doc/bin

Quick Start

Make sure you have a working AeroQuad flight controller board and can connect to it via the USB connection or a wireless serial connection. For STM32 based flight controllers, you'll need to install the virtual com port driver under Windows, available here: http://jleppert.github.io/nodequad/etc/VCP_V1.3.1_Setup.exe.

Nodequad also uses new ES6 harmony features such as Object.observe, which requires node >= 0.11.13. You can obtain a compatible node version here: http://blog.nodejs.org/2014/05/02/node-v0-11-13-unstable.

Usage Example

var Nodequad = require('nodequad');
var vehicle = new Nodequad();

vehicle.probe.andConnect();

vehicle.on('driver.state.connected', function() {
	console.log('Connected to aircraft!');

	console.log('Reading aircraft flight configuration...');
	vehicle.sync('config.vehicle.*');

	console.log('Changing aircraft PID rate pid.');
	vehicle.config.pid.rate.roll = new AeroQuad.PID(1.0, 1.1, 1.2);

	console.log('Monitoring GPS sensor data...');
	vehicle.stream('state.gps');
});


// monitor changes in state
vehicle.on('state.**', function(key, data) {
	console.log('Aircraft state changed:', key, value);
});

// monitor when configuration values get changed
vehicle.on('config.**', function(key, data) {
	console.log('Aircraft configuration changed:', key, value);
});

// monitor communication events from the underlying driver, such as connection, disconnection, etc.
vehicle.on('driver.**', function() {
	console.log('Communication event occured:', this.event);
});
