Shell - API Bindings

The Shell bindings allow you to control Bricks and Bricklets from your shell scripts. The ZIP file for the bindings contains:

  • tinkerforge, a Python script that acts as a shell command

  • tinkerforge-bash-completion.sh, a Bash completion script

  • in examples/ the examples for every Brick and Bricklet

The Shell bindings are based on the Python bindings.

Requirements

  • Python 3.4 or newer

Installation

There are two ways to install the Shell bindings: from our APT repository for Debian based Linux distributions or by manually copying the files to the correct location. But can also be used without installation.

From APT Repository

The bindings are available in our APT repository for Debian based Linux distributions. Follow the setup guide then install the bindings:

sudo apt install tinkerforge-shell

Now you're ready to test an example. The Debian package does not include the examples. Those are available as part of the bindings ZIP file.

Manual Installation

To install the bindings manually copy the tinkerforge file to a folder that is in the PATH. For example, this folder on Linux and macOS:

/usr/local/bin/

On Windows the Scripts/ folder of the Python installation is a good choice:

C:\Python\Scripts\

To be able to call the bindings directly on Windows you have to create a tinkerforge.bat file in the Scripts/ folder with the following content:

@"C:\Python\python.exe" "C:\Python\Scripts\tinkerforge" %*

If your Python is not installed in C:\Python\ then you have to adapt the content of the tinkerforge.bat file accordingly.

Bash Completion

If you're using Bash as your shell then you can use the Bash completion script tinkerforge-bash-completion.sh. If you installed the bindings from our APT repository, then the Bash completion script is already installed correctly and you can skip the following steps.

To install it copy the tinkerforge-bash-completion.sh file to the /etc/bash_completion.d/ an reload the Bash completions with the following command:

. /etc/bash_completion

The Bash completion for tinkerforge can complete options, UIDs, Brick and Bricklet names as well as function and callback names.

Testing an Example

To test a Shell 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.

All examples are meant for typical Unix shells such as Bash. They will work on Linux and macOS as they are. There are Bash ports for Windows that allow to run the examples unmodified, too.

As an example let's test the configuration example for the Stepper Brick. For this copy the example-configuration.sh file from the examples/brick/stepper/ folder into a new folder:

example_project/
 -> example-configuration.sh

If you did not install the bindings then you have to copy the tinkerforge file to the example_project/ folder too:

example_project/
 -> tinkerforge
 -> example-configuration.sh

To make the example find the non-installed tinkerforge file all occurrences of the tinkerforge command in the example-configuration.sh file have to be replaced by ./tinkerforge.

The example starts with a comment about changing the network address using the --host and --port option if it differs from localhost:4223. If the Stepper Brick is connected locally to USB then localhost and 4223 is correct.

# connects to localhost:4223 by default, use --host and --port to change it

To control a Stepper Brick that can be found at host foobar and port 5678 the examples has to be changed as follows: each occurrence of the tinkerforge command has to be replaced by this:

tinkerforge --host foobar --port 5678

The UID value has to be changed to the UID of the connected Stepper Brick, which you can figure out using Brick Viewer:

uid=XXYYZZ # Change XXYYZZ to the UID of your Stepper Brick

Now you're ready to test this example:

./example-configuration.sh
