Embedded World 2022 – June 21-23 – Virtual Schedule

Embedded World 2022

Embedded World 2020 was a lonely affair with many companies canceling attendance due to COVID-19, and Embedded World 2021 took place online only. But Embedded World is back to Nuremberg, Germany in 2022 albeit with the event moved from the traditional month of February to June 21-23. Embedded systems companies and those that service them will showcase their latest solution at their respective booths, and there will be a conference with talks and classes during the three-day event. The programme is up, so I made my own little Embedded World 2022 virtual schedule as there may be a few things to learn, even though I won’t be attending. Tuesday, June 21, 2022 10:00 – 13:00 – Rust, a Safe Language for Low-level Programming Rust is a relatively new language in the area of systems and low-level programming. Its main goals are performance, correctness, safety, and productivity. While still ~70% of […]

SkiffOS minimal Linux for embedded containers now supports Sipeed Nezha RISC-V board

SkiffOS Sipeed Nezha

SkiffOS minimal Cross-compiled Linux for embedded containers has just added support for Sipeed Nezha RISC-V single board computer, and work on the smaller Sipeed Lichee RV board has started. Wait… What is SkiffOS? I’ve never heard about it… That’s how the abstract from the white paper describes it: Embedded Linux processors are increasingly used for real-time computing tasks such as robotics and Internet of Things (IoT). These applications require robust and reproducible behavior from the host OS, commonly achieved through immutable firmware stored in read-only memory. SkiffOS addresses these requirements with a minimal cross-compiled GNU/Linux system optimized for hosting containerized distributions and applications, and a configuration layering system for the Buildroot embedded cross-compiler tool which automatically re-targets system configurations to any platform or device. This approach cleanly separates the hardware support from the applications. The host system and containers are independently upgraded and backed-up over-the-air (OTA). In other words, that’s […]

OpenRemote fully open-source IoT platform targets OEMs and DIY projects

OpenRemote Architecture

OpenRemote claims to be a 100% open-source IoT platform suitable for DIYs as well as OEMs. The asset management platform can help with the tracking of vehicle fleets, energy systems, or crowds, help to build smart cities, smart buildings, smart airports, and more. While most cloud IoT platforms rely on open-source tools, the software hosted on the providers’ servers is usually closed-source as we’ve seen in our comparison between Microsoft Azure IoT, Balena, and Particle, but OpenRemote is different will the full stack being released under an AGPLv3 open source license. OpenRemote 3.0 software is comprised of four main blocks: The Frontend is comprised of Consoles (native iOS and Android apps), Web components and Templates, as well as a System Administration interface used to create dashboards and control panels. Manager – headless Java application to capture the current asset states and includes Asset Management, State & Historical Data, Event Processing […]

ClusBerry Rack houses up to four hot-swappable Raspberry Pi CM4 modules

Clusberry Rack

TECHBASE ClusBerry Rack supports up to four Raspberry Pi CM4 based modules which can be added and removed on the fly thanks to a lockable mechanism that reminds me of hot-swappable drives found in NAS. Using the same ClusBerry I/O mainboards as found in the earlier ClusBerry 9500-CM4 and ClusBerry-2M industrial systems, each Raspberry Pi Compute Module 4 inside the ClusBerry Rack offer one Gigabit Ethernet port, one USB host, one micro USB service port, and an RS-232/485 serial port. TECHBASE is not the best company when it comes to describing its products, possibly because those are customizable, and in this case, they don’t show the other side of the enclosure with all ports… But based on the PDF we’ve received, you should be able to create a system with four modules offering the following features each: Optional video output – HDMI Networking – 1x Gigabit Ethernet port (option for […]

Combining OSTree and SW Containers for reliable IoT Device updates

OSTree IoT devices

CNXSoft: This is a guest post by Drew Moseley, Technical Solutions Architect at Toradex, explaining how the company updates Linux IoT devices firmware with OSTree (aka libostree) open-source operating system build and deployment tool, as well as Docker software containers. Every day more and more connected devices are being brought to market and estimates for the total size of the Internet of Things (IoT) market are as high as $1.5 trillion by 2027. Gas pumps, medical devices, and point of sale systems are increasingly connected, making it virtually impossible to avoid interacting with these devices, even for complete Luddites. In the home, devices such as power meters, light switches, and security cameras are commonly internet-enabled allowing for smart home functionality. The level of complexity in the software for these devices increases with the functionality, and the number of devices with software defects in the field is growing. In many cases, […]

ClusBerry-2M Industrial IoT controller takes two Raspberry Pi Compute Modules 4

ClusBerry-2M Industrial IoT controller

Earlier this year, Techbase introduced the ClusBerry 9500-CM4 cluster system for industrial IoT that can take up to eight Raspberry Pi Compute Modules 4 housed in a DIN rail enclosure. But for smaller projects and IoT prototyping, the company has now designed ClusBerry-2M, a smaller cluster device including two independent ModBerry I/O mainboards and two Compute Module 4’s that’s equivalent to two ModBerry 500-CM4, but with support for software cluster management tools such as Docker and K3s Lightweight Kubernetes. The company did not share the full ClusBerry-2M specifications, but we can derive most of the features from the photos, previous products features, and the announcement: SoM – 2x Raspberry Pi Compute Module 4 with Broadcom BCM2711 quad-core Cortex-A72 processor @ 1.5 GHz, 1 to 8GB RAM, up to 32GB eMMC flash. Storage – 2x M.2 slots for NVMe SSDs Video Output – 2x HDMI 2.0 ports Connectivity 4x Gigabit Ethernet […]

Use Scheme functional programming language with LambdaChip Alonzo STM32 board

LambdaChip Alonzo STM32 Scheme functional programming

Most MCU-based embedded systems come with firmware programmed with assembler, C, and/or C++.  But as referenced in a paper published in 2000 entitled ” Point of view: Lisp as an alternative to Java“, functional programming languages like Lisp or Scheme may lead to shorter development times compared to C/C++ or Java. That’s with this idea in mind that LambdaChip was created. It is a lightweight, open-source virtual machine designed to run on embedded systems with limited resources, for instance, an 80MHz microcontroller with 50KB RAM, and programmable with Scheme multi-paradigm programming language, a dialect of Lisp widely used for functional programming research and teaching. The company behind the project, also called LambdaChip, has just created its own hardware with LambdaChip Alonzo, an STM32 Cortex-M4 development board with 512KB flash, 128KB RAM, and that also comes with Bluetooth LE connectivity. LambdaChip Alonzo board specifications: MCU – STMicro STM32F411CEU6 Arm Cortex-M4 MCU […]
