WireST SDK

WireST SDK is a library for Linux gateways that allows easy access to the data exported by an IO-Link device that implements the IOLinkST Protocol.

Documentation

Documentation can be found here.

Compatibility

This version of the SDK is compatible with Python 3.5 and runs on a Linux system.

Preconditions

The WireST SDK makes use of the pySerial Python interface to serial ports on Linux.

$ sudo pip3 install pyserial

Moreover, it uses the concurrent.futures module to run pools of threads in background, that serve listeners' callbacks.

$ sudo pip3 install futures

Installation

The WireST SDK can be installed through the Python pip package manager.

$ sudo pip3 install wire-st-sdk

Setting up the application examples

Before running the application examples, please prepare your devices as described here below:

• The example_iolink_1.py application example shows how to connect IO-Link devices to a Linux gateway, to set their parameters, and to get data from them. The application requires to have a masterboard, e.g. the STEVAL-IPD004V1 evaluation board, connected to IO-Link devices, e.g. the STEVAL-IPD005V1 evaluation board, with a FW compatible with the IOLinkST Protocol.

Other application examples which show how to send data to the cloud can be found within the EdgeST SDK for Linux, an IoT edge computing abstraction library for Linux gateways.

Running the application examples

To run the application examples please follow the steps below:

1. Install the WireST SDK as described by the Installation chapter.
2. Clone the WireST SDK git repository to download the application examples:

$ git clone https://github.com/STMicroelectronics/WireSTSDK_Python.git

3. Enter the "wire_st_examples/iolink" folder and run the desired script:

$ sudo python3 example_iolink_x.py
