The exFAT file system is about to get faster in Linux 6.2, at least when creating files and directories, with the performance boost especially noticeable on low-end processors. Microsoft released the exFAT specification and announced Linux support in August 2019, which was followed by a new exFAT implementation in Linux 5.7 (June 2020) from Samsung. But people are still working on improving exFAT Linux support, and Yuezhang Mo, an engineer at Sony, committed a patchset for Linux 6.2 that reduces repeated traversal of directory entries to boost the performance of exFAT: After traversing all directory entries, hint the empty directory entry no matter whether or not there are enough empty directory entries. After this commit, hint the empty directory entries like this: 1. Hint the deleted directory entries if enough; 2. Hint the deleted and unused directory entries which at the end of the cluster chain no matter whether enough [...] The post Linux 6.2 exFAT update to improve performance when creating files and directories appeared first on CNX Software - Embedded Systems News.

It’s now possible to make use of the Pinecil V2 soldering iron‘s Bluetooth LE connectivity through a web-based interface used to monitor and/or set the temperature and power of the RISC-V soldering iron. When the Pinecil V2 soldering iron was launched with a Bouffalo Lab BL706 RISC-V Bluetooth microcontroller last summer, we were told there were main potential cases to make use of the Bluetooth LE features: OTA firmware upgrade and remote telemetry and control. The latter is now being taken care of by Joric who has written a web application to visualize telemetry data and even control the temperature of the soldering iron. To be able to use the Bluetooth features, you’ll first need to install the latest Pinecil V2 firmware with blisp flashing utility before going to https://joric.github.io/pinecil to pair your soldering iron as explained in the wiki. Note the implementation relies on the Web Bluetooth API which [...] The post Pinecil V2 Bluetooth LE soldering iron gets a web interface appeared first on CNX Software - Embedded Systems News.

There is no way to support this on s905 TV Boxes while reusing the android u-boot as the android uboot on s905 conflicts with the partition table location of standard mainline linux (this only impacts s905 boxes; s905x[wl], x2, x3, etc will work). So this removes the old script that claimed to support this. The Amlogic TV Box install instructions on the forum have been updated to reflect this change.

OpenPLC is an open-source, free-to-use Programmable Logic Controller Suite, compliant with the IEC 61131-3 standard, and working with a range of hardware platforms such as Arduino, ESP8266/ESP32, Raspberry Pi SBCs, as well as Windows and Linux machines. When Arduino unveiled the Arduino PLC IDE, we noted the languages defined by the IEC 61131-3 standard were licensed, and the PLC key for the Portenta Machine Control unit sold for $17.60. One reader complained about the high license cost per device, but Massimo Banzi, the co-founder of the Arduino project, replied it was cost-effective for smaller deployments: Actually it’s not that much money compared to the cost of other PLC software (thousands of dollars per seat!). This model helps small companies with not that many devices.. It’s possible to negotiate bulk licenses for companies. But there’s also another option with OpenPLC open-source PLC suite that does not require any license fee. That’s [...] The post OpenPLC open-source Programmable Logic Controller Suite works with Arduino, ESP8266/ESP32, Raspberry Pi, etc. appeared first on CNX Software - Embedded Systems News.

Quantum computing promise a leap in the performance of applications relying upon parallelism using the properties of quantum physics like superposition, interference, and entanglement to perform computation instead of flipping “0” and “1” like traditional transistors. It will be used in scientific simulations, cryptography, machine learning, computational biology, and more. So far, I had seen massive quantum computers in research labs, but companies like Intel and IBM are working on providing quantum processors with hundreds and thousands of qubits that should eventually be found in supercomputers. It’s unclear to me whether we’ll ever see “quantum accelerators” in embedded processors, and in any case, it would be many years away. But if you are interested in better understanding the technology and playing around with quantum computing, SpinQ has been selling 2 or 3-qubit quantum computers for the education market: Gemini Mini, Gemini, and Triangulum.

TwoTrees TS2 is a laser engraver with a 10W laser, and the company sent us a sample for review. I usually let Karl review this type of hardware as he’s done previously with the Ortur Laser Master 2 Pro laser engraver, but he happens to be busy with another 10W laser engraver from a different company, so I decided to try it out myself this time around. I’ll write a two-part review, with the first part checking out the specifications, unboxing the package, and reporting my experience assembling my very first laser engraver, before engraving and cutting various materials in the second part of the review. TwooTrees TS2 laser engraver specifications Basic TS2 specifications provided in the user manual: Laser Power – 10 Watts Wavelength – 445 nm +/-5 Control board – Makerbase DLC32 V.20 with ESP32-WROOM-32U module Engraving accuracy – 0.1mm Engraving speed – 10,000mm per minute Engraving size [...] The post TwoTrees TS2 laser engraver review – Part 1: Unboxing and teardown appeared first on CNX Software - Embedded Systems News.

Olimex has started to take pre-orders for the AgonLight2, a customized version of the Agon Light 8-bit open-source hardware computer based on the Z80 family and running BBC Basic. Bernardo Kastrup and Dean Belfield created the Agon light 8-bit retro computer with VGA and PS2 keyboard port and programmable with BASIC earlier this year and released all hardware design files, the firmware, and documentation on GitHub, and Dean uploaded a one-hour-long video on YouTube. It was designed with EasyEDA, but Olimex re-captured the design in KiCad after getting customer requests, and the new cost-optimized board named AgonLight2 will start shipping by the end of January 2023.
