Joystick

This package provides the Gobot adaptor and drivers for the PS3 controller, Xbox 360 controller, or any other joysticks and game controllers that are compatible with Simple DirectMedia Layer.

Getting Started

This package requires sdl2 to be installed on your system

OSX

To install sdl2 on OSX using Homebrew:

$ brew install sdl2

Ubuntu

$ sudo apt-get install libsdl2-2.0-0

Now you can install the package with

go get github.com/hybridgroup/gobot && go install github.com/hybridgroup/gobot/platforms/joystick

Usage

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