  • IAR Systems extends functional safety offering for RISC-V with leading build tools for Linux

    IAR Systems®, the future-proof supplier of software tools and services for embedded development, today announced that its build tools for RISC-V supporting deployment in Linux-based frameworks have been certified by TÜV SÜD for functional safety development. The certification has been performed according to the requirements of IEC 61508, the international umbrella standard for functional safety, as well as ISO 26262, which is used for automotive safety-related systems. In addition, the certification covers the international standards IEC 62304 for medical software, IEC 60730 for Household Appliances, ISO 13849 and IEC 62061 for Machinery Control Systems, IEC 61511 for Process Industry, ISO 25119 for Agriculture and Forestry, and the European railway standards EN 50128 and EN 50657.

  • Allwinner D1s/F133 RISC-V processor integrates 64MB DDR2 - CNX Software

    Allwinner D1s (aka F133) is a cost-down version of Allwinner D1 RISC-V processor introduced earlier this year together with a Linux capable development board, with the main difference being the integrated 64MB DDR2.

    Besides the built-in RAM, Allwinner D1s comes with many of the same features as D1 RISC-V SoC, but loses HDMI output and the HiFi 4 audio DSP, and Allwinner made some tweaks to the IOs with one less I2S audio interface, and general-purpose ADC.

  • Smart Power 3 - A $45 smart power analysis tool for embedded systems developers - CNX Software

    Hardkernel has launched a number of popular Arm SBC’s with the ODROID family over the years, but the Smart Power 3 is a different type of product, as the ESP32-based smart power meter can help embedded systems engineers optimize their hardware and software power consumption and/or check for spurious power peaks during boot up or shutdowns.

    In the past, we’ve reviewed relatively expansive tools like Qoitech Otii Arc or gone the DIY route, but at $45, Hardkernel offers a power monitoring solution that’s both inexpensive and easy to use, albeit with fewer features than Qoitech’s device.

  • Omni-Wheeled Cane Steers The Visually-Impaired Away From Obstacles | Hackaday

    The cane uses a Raspi 4 with camera to detect objects, and a 2-D LIDAR to measure the distance to those objects. There’s a GPS and a 9-DOF IMU to find the position and orientation of the user. Their paper is open, too, and it comes with a BOM and build instructions. Be sure to check it out in action after the break.

LibreOffice Base Guide 7.2 has been released

The LibreOffice Documentation Team releases the Base Guide 7.2, based on refactored content from the Base Guide 6.4, with the 7.2 branding and text layout. It covers LibreOffice’s database component. The team decided to just fast-forward the release number, given the very little developments for Base since LibreOffice 6.4. The team intended to complete the Guide set for LibreOffice 7.2 and get ready to update contents of the set for the forthcoming LibreOffice 7.3 release. The LibreOffice Base Guide is a community effort that include valuable collaboration from Robert Großkopf, Pulkit Krishna, Dan Lewis, Drew Jensen (In Memoriam), Peter Schofield, Jost Lange, Steve Schwettman, Jean-Pierre Ledure, Jochen Schiffers, Martin Fox, Alain Romedenne, Jenna Sargent, Hazel Russman, Andrew Pitonyak and Randolph Gamo.

Krita 4 splash screen

This easter egg is not part (yet) of Krita 5, will not be part of the release of 5.0 coming soon and that's good: you don't want to miss the new splash screen from Tyson Tan with the larger size in Krita 5. It's splendid! But for sure I'll try to propose an illustration for later Krita 5.1 or 5.2 release, one that could be ready before December 2022. Feel free to also contribute to make ones (it's not just a privilege I had), you just need to propose your artwork made with Krita, with an aspect ratio for this format, about the season, and with a permissive license (eg. CC-By 4.0). Don't forger to post-it on https://krita-artists.org/ , so the community and developers can see it. Read more

LoRa expansion boards work with Raspberry Pi SBC and Raspberry Pi Pico board (Crowdfunding)

We’ve covered a number of LoRa solutions based on Raspberry Pi boards, and SB Components is now offering another with the LoRa HAT for Raspberry Pi equipped with an Ebyte E22 LoRa module operating in either the 433 MHz, or 868 and 915 MHz bands. The company also offers a LoRa expansion for Pico based on the same E22 module, adding a small 1.14-inch LCD for information display, and designed for the Raspberry Pi Pico board with the RP2040 dual-core Cortex-M0+ microcontroller.
