What is COOL?

COOL - Compact OSADL Online Lectures: Open Source meets Industry

  • COOL is an OSADL webinar series.
  • COOL takes place regularly once a month and covers new and state-of-the-art topics on Open Source software in industry, either on legal or on technical aspects.
  • COOL editions each consist of two lectures covering a special "Open Source meets industry" topic followed by a discussion round. The first "basic" lecture provides basic knowledge with regard to the respective topic and the second "advanced" lecture dives deeper into the topic and highlights special aspects. The discussion round gives all participants the possibility to ask questions and discuss with the respective speakers and the audience.
  • COOL speakers are OSADL experts on the one hand and external specialists on the other hand who kindly agreed to share their expert knowledge on the respective topic.
  • COOL is a virtual event. The lectures are held by live video streams. Speakers will be available for questions and discussion in a video conference which will take part subsequent to the live video streams.
  • COOL in general is designed to provide support how to best and compliantly use Open Source software in industry.

Description COOL April 2025 edition:

Machine controllers as well as many other devices heavily and increasingly rely on data that are measured and collected by different sensors. Temperature sensors, proximity sensors, accelerometers and potentiometers are just a few examples of common data sources that have to be dealt with in industrial systems and therefore need driver support and an appropriate abstraction layer in the operating system. To cover this need Linux offers the “Industrial I/O subsystem”. It can basically integrate everything that acts as a sensor. Filling the gap between the hardware monitoring subsystem hwmon and the input subsystem it offers a generic and unified sensor interface for configuration, triggering measurements, reading data and signaling when data are ready.

In the theoretical part of this COOL edition, Andreas Klinger (IT Klinger) will present the concept of the industrial I/O subsystem (IIO), covering the design, the structure of IIO drivers and device tree integration. In the practical part I, Andreas will explain how IIO works from the user's perspective, looking into the abstraction layer and how to use it.

Jan Altenberg and Alexander Bähr from OSADL will then, in the practical part II, look into a few examples in the OSADL QA farm, showing how sensors are being integrated with IIO in industrial devices.

Recommended audience COOL April 2025 edition:

Linux kernel developers, software developers, software engineers, system architects, system integrators, field application engineers
