Panfrost open-source driver for Arm Mali Bifrost and Midgard GPUs has come a long way, and Hardkernel’s ODROID-N2+ board now supports Ubuntu 21.10 and Chromium OS with 3D graphics acceleration through the Panfrost driver. As a reminder, ODROID-N2+ is a single board computer powered by an Amlogic S922X Rev.C processor clocked at 2.4GHz with an Arm Mali-G52 GPU, with up to 4GB RAM, and which comes with HDMI 2.0, Gigabit Ethernet, four USB 3.0 ports, plus a GPIO header. ODROID-N2+ with Ubuntu 21.10 + Panfrost Ubuntu 21.10 Impish Indiri is supposed to be released on October 14, 2021 together with Gnome 40, but Hardkernel released a development version as early as August, with Linux 5.14 and Panfrost GPU acceleration as you can see from the screenshot above. The Ubuntu 21.10 image for ODROID-N2+ and the earlier ODROID-N2 SBC cannot be found in the Wiki just yet, but should be there […]
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.

Heatshrink – An ultra-lightweight compression library for embedded systems
When I wrote about Bangle.js 2 JavaScript smartwatch yesterday, I noticed they used “Heatshrink compression” in ESPruino firmware. I can’t remember ever reading about Heatshrink before, and indeed there are no results while searching on CNX Software. Heatshrink is an open-source data compression library designed for resources-constrained embedded systems that works with as little as 50 bytes of RAM. That’s impressive, so let’s investigate. The library is written in C language and was released about 8 years ago on Github with the following key features: Low memory usage – As low as 50 bytes with specific parameters, and usually under 300 bytes are needed. Incremental, bounded CPU use – Input data is processed in tiny bites Static or dynamic memory allocation Released under an ISC license which allows you to use the library freely, even in commercial products. The internal workings of the library are explained as follows: Heatshrink is […]
Data acquisition SBC offers PCIe/104 and mPCIe expansions
