Gobot Adaptor for Joysticks and Game Controllers

Gobot (http://gobot.io/) is a library for robotics and physical computing using Go

This repository contains the Gobot adaptor for the PS3 controller, Xbox 360 controller, or any other joysticks and game controllers that are compatible with Simple DirectMedia Layer (SDL) (http://www.libsdl.org/).

For more information about Gobot, check out the github repo at https://github.com/hybridgroup/gobot

Getting Started

Installing gobot-joystick requires sdl2 to be installed on your system

Ubuntu

$ sudo apt-get install libsdl2-2.0-0

Now you can install gobot-joystick with

$ go get github.com/hybridgroup/gobot-joystick

Usage

Controller configurations are stored in JSON format. Here's an example configuration file for the Dualshock 3 controller
