Go - API Bindings

The Go bindings allow you to control Bricks and Bricklets from your Go programs. The ZIP file for the bindings contains:

  • in github.com/Tinkerforge/go-api-bindings the source code of the bindings
  • in examples/ the examples for every Brick and Bricklet

Requirements

  • Go compiler 1.11 or newer

Installation

There are three ways to install the Go bindings: from our APT repository for Debian based Linux distributions or from GitHub or from source.

From APT Repository

Note

According to Debian Go packaging guidelines the content of this package is not available to users in their regular development workflow by default. This package is meant to be used as dependency for other Debian packages only. The guidelines recommend that users in their regular development workflow should use the go get tool to download the bindings from GitHub.

The bindings are available in our APT repository for Debian based Linux distributions (in this case you don't even need the ZIP file for the bindings). Follow the setup guide then install the bindings:

sudo apt install golang-tinkerforge-dev

The bindings are installed to:

/usr/share/gocode/src/github.com/Tinkerforge/go-api-bindings

To use these bindings regardless of the Debian guidelines, /usr/share/gocode has to be added to the GOPATH.

The Debian package does not include the examples. Those are available as part of the bindings ZIP file.

From GitHub

The bindings are available from the GitHub (in this case you don't even need the ZIP file for the bindings). Install the bindings using the go get tool:

go get -u github.com/Tinkerforge/go-api-bindings

This does not include the examples. Those are available as part of the bindings ZIP file.

From Source

Extract the github.com directory from the ZIP file to the src directory of your GOPATH.

Now you're ready to test an example.

Testing an Example

To test a Go example Brick Daemon and Brick Viewer have to be installed first. Brick Daemon acts as a proxy between the USB interface of the Bricks and the API bindings. Brick Viewer connects to Brick Daemon and helps to figure out basic information about the connected Bricks and Bricklets.

As an example let's compile the configuration example for the Stepper Brick from the command line. For this we use the example_configuration.go file from the examples/StepperBrick/ folder of the ZIP file.

In the example ADDR specifies at which network address the Stepper Brick can be found. If it is connected locally to USB then localhost:4223 is correct. The UID value has to be changed to the UID of the connected Stepper Brick, which you can figure out using Brick Viewer:

const ADDR string = "localhost:4223"
const UID string = "XXYYZZ" // Change XXYYZZ to the UID of your Stepper Brick.

Now we can build and run the project with go run example_configuration.go.
