Go + hardware

This repo is a directory of tools, packages and tutorials to let you introduce Go in your hardware projects.

Why Go?

• Great tooling that comes with a strong cross compilation story.
• Builtin concurrency primitives in Go is making it easier to write concurrent programs.
• Go runs on ARM boards. ARM boards are getting cheaper, making it easier for production designs to include them. Higher-level languages have more opportunities than ever on hardware projects.
• Go is garbage collected but you can still use it to write non-realtime or networked controllers. There are plenty of Go users who program their experimental drone flight control software in Go, it's OK for prototyping.
• Go's network stack is maintained well. Standard library might be missing higher level implementations for P2P protocols, but the community works to fill that gap.
• Writing C bindings in Go is a pleasure with cgo.

Tutorials

• An introduction to cross compilation with Go
• Go on ARM tips, known issues and success stories

Packages

Controllers, robotics, etc

• gobot - High level Go package with a variety of platform APIs to talk to popular drivers such as GPIO on Arduino and Raspberry Pi, Leap Motion or Pebble.
• embd - Embedded programming framework for Go.
• fadecandy - Dithering OPC-based LED controller
• godrone - High level Parrot AR Drone 2.0 framework written in Go.
• launchpad - High level controller library for Novation Launchpad.
• littlebits - littleBits controller for Go. It requires USB I/O module.
• hwio - Hardware library for ARM boards such as Raspberry Pi and BeagleBone, loosely based on Arduino.
• go-lepton - Streams images taken on a FLIR Lepton connected to a Raspberry Pi SPI port to over via WebSockets via embedded HTTP server.

Signal processing, computer vision, graphics, media

• go-gl - OpenGL bindings for Go.
• go-opc - Open Pixel Control bindings for Go.
• go-opencv - OpenVM bindings for Go.
• go-sox - SoX bindings for Go.
• portaudio - PortAudio bindings for Go.
• portmidi - PortMidi bindings for Go.
• go-osc - Open Sound Control (OSC) bindings for Go.
• openvg - 2D Graphics library wrapping the OpenVG API

Networking

• mdns - mDNS server and client implementation in Go. Multicast DNS can be used to discover services and message on the local network without the use of an authoritative DNS server.
• gatt - Provides a Bluetooth Low Energy GATT implementation.
