Embedded World 2022 – June 21-23 – Virtual Schedule

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 […]

FOSDEM 2022 schedule with embedded Linux, IoT, automotive… sessions

While typically taking place in Brussels, Belgium, FOSDEM 2022 will take place online just like FOSDEM 2021 due to COVID-19 restrictions. The good news is that it means anybody can attend it live from anywhere in the world, and makes it more like “FOSDIM”, replacing European with International, in “Free and Open Source Developers’ European Meeting”. FOSDEM 2022 will take place on February 5-6 with 637 speakers, 718 events, and 103 tracks. I’ve made my own little virtual schedule below mostly with sessions from the Embedded, Mobile and Automotive devroom, but also other devrooms including “Computer Aided Modeling and Design”, “FOSS on Mobile Devices”, “Libre-Open VLSI and FPGA”, and others. Saturday, February 5, 2022 12:30 – 13:00 – Five mysteries in Embedded Linux by Josef Holzmayr Once you start out in embedded Linux, there is a lot to do. Some things are obvious, some less so. First and foremost, […]

Board with 25 RGB LEDs is offered with ESP32-C3 or ESP32-Pico-D4

In case you are in need of a tiny WiFI or Bluetooth-connected board with an RGB LED matrix, two have shown up on Banggood with basically the same 25 RGB LED design , except “C3FH4 RGB” board is based on ESP32-C3 RISC-V SoC, while the other, named “PICO D4 RGB“, features ESP32-Pico-D4 SiP (System-in-Package). The boards are cute and the main purpose is probably for decoration/ornament, but I’d imagine if you purchase a few they could also be used as an experimentation/education platform for mesh networking, using the ESP Mesh Development Framework (ESP-MDF) for instance. C3FH4 RGB / PICO D4 RGB board specifications: SoC/SiP C3FH4 RGB board – ESP32-C3FH4 SoC with RISC-V core @ 160 MHz, 4MB flash, 2.4GHz Wi-Fi, and Bluetooth 5 LE with Long-Range support PICO D4 RGB board – ESP32-PICO-D4 system-in-package with ESP32 dual-core Xtensa processor @ 240 MHz, 2.4GHz Wi-Fi and Bluetooth dual-mode, 4MB flash Ceramic […]

Fujitsu introduces Wirepas Massive USB dongle for location tracking, IoT mesh networking

I was first introduced to Wirepas Massive mesh networking a few days ago when I covered Solidrun Solidsense N8 IoT Compact Wirepas Massive gateway comprised of an NXP i.MX 8M Nano processor running Linux and a module based on Nordic Semi nRF52832 wireless MCU handling Wirepas Massive through its 2.4 GHz radio. It turns out there’s an easy way to add the new mesh networking technology to existing gateways: USB dongles. Fujitsu has launched the FWM8BLZ09x Wirepas Massive USB dongle family, based on the more recent nRF52833 SoC, with Anchor, Tag, and Sink models. Fujitsu FWM8BLZ09x specifications: USB Dongle Types Anchor – FWM8BLZ09P Tag – FWM8BLZ09T Sink – FWM8BLZ09S Wireless MCU – Nordic Semi nRF52833-CJAA Cortex-M4 microcontroller @ 64 MHz with 8 KB RAM, 512 KB Flash, 2.4 GHz radio Connectivity Wirepas Massive mesh networking Transmit power – +8dBm max. Carrier frequency – 2,400MHz to 2,483.5MHz Modulation – GFSK Symbol rate […]
