Analog expands Linux distribution to support high-performance solution development

Thu, Dec 09, 2021

This year, as Linux open-source operating system marks its 30th anniversary, ADI has expanded its Linux distribution by adding more than 1,000 ADI peripherals supported by in kernel Linux device drivers.

The new Linux distribution focuses on ready-to-use in kernel Linux device drivers, offering a robust system for software development, reducing risk and development time with pre-existing code that is peer-reviewed and backed by industry. The distribution contains the essential components for running the built-in drivers and enables customers to integrate custom software. By providing hardware and software compatibility across the customers’ full ecosystem, the Linux distribution will help prevent hardware lock-in while also minimising software development needs.

Designed to enable the rapid development of embedded solutions, these open-source device drivers streamline the software development process for ADI’s customers, providing access to tested, high-quality software to create solutions across a range of industries, including telecom, industrial, military, aerospace, medical, automotive, security and Internet of Things. This portfolio includes products from Maxim Integrated Products which is now part of Analog Devices.

“With these drivers, we can serve our customers in a more holistic manner by streamlining the software development process and making it more cost and resource efficient,” said David Babicz, director of engineering at ADI. “Using open-source, tested code that they know will work in lockstep with their hardware means customers can focus on innovating instead of building software from scratch, helping them get their products to market faster.”

As part of the milestone celebration, ADI has released Kuiper Linux, a free Linux-based operating system based on Raspbian/Debian that is optimised for ADI peripherals and that supports ARM-based systems such as Raspberry Pi, Xilinx Zynq, Xilinx Zynq Ultrascale+ MPSoC, Intel Cyclone V SoC, Intel Arria 10 SX SoC and Intel Stratix 10 SoC.

For the past 15 years, engineers within Analog Devices and collaborating organisations have developed Linux kernel device drivers in a range of Linux subsystems across ADI’s product portfolio including audio, battery charging and management, real-time clocks, power management, video, industrial input/output, accelerometers, amplifiers, A/D converters, D/A converters, beamformers, phased lock loop, gyroscopes, inertial measurement unit, input devices, networking, and universal serial bus.

Version 3 NanoEdge AI Studio offers streamlined solution

Tue, Dec 07, 2021

The shift of artificial intelligence (AI) capabilities from the cloud to the edge has given rise to this new version of NanoEdge AI Studio from STMicroelectronics to help simplify the creation of machine learning, anomaly learning, detection and classification on any STM32 microcontroller. This new release also includes prediction capabilities such as regression and outliers libraries. The tool, says the company, makes it easier for users to integrate such machine-learning capabilities quickly, easily and cost-effectively into their equipment. It emphasises that no data-science expertise is needed. There is improved support for anomaly detection, which ST says is particularly useful for predictive maintenance to anticipate wear-and-tear phenomena or to better deal with equipment obsolescence.

Adding native support for all STM32 development boards, ST has also eliminated the need to write code for its industrial-grade sensors with new high-speed data acquisition and management capabilities.

Regression algorithms have been added to extrapolate data and predict future data patterns for energy management or forecasting remaining life of equipment.

Applications include connected devices, household appliances and industrial automation.

Steve Peguet, scientific director, innovation department of Alten Group, an international technology consulting and engineering company, said: “We had the opportunity to use NanoEdge AI Studio with one of our major aerospace customers. For machine drilling during the manufacture of expensive parts, where a worn drill-bit or the slightest anomaly can have significant consequences, Alten used NanoEdge AI Studio to integrate Machine-Learning algorithms into the drilling equipment. The solution tested on a production line was so effective that Alten has launched a practice around this technology to support its customers and to industrialise these first results to deploy a disruptive solution of drilling tools prescriptive maintenance in their factories.”
