Pocket P.C. devkits ship, U-blox GNSS module replaced by SIMCom SIM33ELA

The Pocket P.C. (aka Popcorn Computer) is a handheld Linux computer based on Allwinner A64 with 2GB RAM, 32GB storage, a 4.95-inch Full HD display, and a QWERTY keyboard that was introduced in 2019, and reminds me of PocketCHIP from a few years also with an Allwinner processor, a display, a keyboard, and a battery. The initial plan was to start shipping the device by May 2020, and there are been delays for reasons we’ll explain below, but the good news is that Source Parts has just announced the developer units had been shipped. So what happened exactly, besides the COVID-19 pandemic, government lockdowns, and supply chain disruptions? Source Parts first encountered issues with the quality of PCBs delivered by the manufacturer, which ended up with them having to switch to a new manufacturer. Getting the display to work was also a challenge, and Icenowy, a developer involved with linux-sunxi […]

Open-source Allwinner V3 ISP driver to enable blob-free camera support in mainline Linux

Bootlin has just submitted the first patchset for the Allwinner V3 image signal processor (ISP) driver in mainline Linux which should pave the way for a completely open-source, blob-free camera support in Linux using V4L2. There are several blocks in an SoC for camera support including a camera input interface such as MIPI CSI 2 and an ISP to process the raw data into a usable image. Add to this the need to implement the code for sensors, and there’s quite a lot of work to get it all working. Allwinner SDK comes with several binary blobs, aka closed-source binary, but Bootlin is working on making those obsolete, having first worked on Allwinner A31, V3s/V3/S3, and A83T MIPI CSI-2 support for the camera interface driver in the V4L2 framework (and Rockchip PX30, RK1808, RK3128 and RK3288 processors), as well as implemented support for Omnivision OV8865 and OV5648 image sensors earlier […]

ODROID-N2+ SBC gets Ubuntu 21.10, Chromium OS with Panfrost open-source GPU driver

ODROID-N2+ running Ubuntu 21.10 with Panfrost

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. 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.

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 […]
