chip-io

Johnny-Five IO Plugin for the Next Thing Co. C.H.I.P.

Prerequisites

• Next Thing Co. C.H.I.P. board
• Node.js installed
  1. Install curl: sudo apt-get install curl
  2. Follow Debian section of NodeSource installations instructions
• Build essential installed: sudo apt-get install build-essential
• Add chip user to i2c group: sudo adduser chip i2c

NOTE: Some GPIO pins require root or sudo.

Getting Started

npm install chip-io johnny-five

NOTE: Must be run on the C.H.I.P. itself.

Boilerplate Program

var five = require('johnny-five');
var chipio = require('chip-io');

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

board.on('ready', function() {
  // do Johnny-Five stuff
});

Examples

See examples folder as well as Johnny-Five examples.

API
