We’ve already covered inexpensive offline voice recognition modules based on US516P6 or TW-ASR ONE microcontrollers that allow people to add smarts to their projects without a network connection for improved privacy and lower latency. Those are great in theory, but at the time (April 2022) documentation was lacking or only in Chinese, and they were fairly hard to use based on some of the comments in my earlier posts. But today, I’ve noticed DFRobot is now selling the “Gravity: Offline Voice Recognition Sensor – I2C & UART” module with support for Arduino programming, and it looks fairly easy to customize as we’ll see further below. Gravity Voice Recognition DF2301QG module specifications: Voice recognition module – WS-2520-TR module with MCU – TBD 121 commonly used fixed voice commands, one-fixed wake word Support for 1 learned wake-word, 17 user-defined commands Audio Output – Built-in speaker and external speaker interface Input – Dual [...] The post Offline voice recognition module supports Arduino programming, custom voice commands appeared first on CNX Software - Embedded Systems News.

We first spotted the AMD Ryzen Embedded 5000 processors in a micro-ATX motherboard last August, but AMD has now only announced the availability the of Ryzen Embedded 5000 Series “Zen 3” processors designed for “always on” networking firewalls, network-attached storage systems, and other security applications. AMD also mentions the Ryzen Embedded 5000 are “power-efficient processors”, but that does not mean low power, as those embedded processors are 65 to 105W parts, and offer a step-up in performance from the 10 to 54W AMD Ryzen Embedded V3000 processors also targetting networking and storage applications. As we found out last year, four SKUs are available with the Ryzen 5950E, Ryzen 5900E, Ryzen 5800E, and Ryzen 5600E, but the specifications are a little different, as for instance, there’s no 10-core part. All four are AM4-socket processors, support two DDR4 channels up to 3200MT/s, and come with 24 PCIe Gen4 lanes, and when optionally [...] The post AMD Ryzen Embedded 5000 processors launched for networking applications appeared first on CNX Software - Embedded Systems News.

The 100ASK-V853-Pro board is a development kit consisting of an Allwinner V853 system-on-module board (SoM) and a feature-rich carrier board with a large number of interfaces. Allwinner V853 supports up to 1TOPS of NPU computing power and is mainly for AI vision application development. The core board contains a DDR and eMMC as well as a PMU chip (AXP2101) and is connected to the carrier board through a board-to-board connector. All the functional resources of the V853 are drawn out through the carrier board. The carrier board comes with 2-channels CSI camera interfaces as well as RGB and MIPI DSI display interfaces. Although 1 TOPS of AI computing power is not outstanding, the NPU can still be used to accelerate AI vision applications at the edge. The board also comes with four USB 2.0 ports (two Type-A, two Type-C), an 100Mbps Ethernet port, a 22-pin header for expansion, and five [...] The post 100ASK-V853-Pro – A feature-rich Allwinner V853 board designed for AI vision applications appeared first on CNX Software - Embedded Systems News.

Description After today's complete stall of primary Ubuntu infrastructure I switched to mirrors in order to rebuild caches. First problem is that often mirrors for amd64 and others are placed on different locations. This part is covered but it fails for riscv64 architecture. In order to cover that too, its better to have more generic variable CUSTOM_UBUNTU_MIRROR_PORTS and have everything that is not amd64 there. By quick research - if mirror hosts arm64 it also hosts risv64 and vice versa. Second problem - if caches are re-generated with 3rd party mirrors, release lists remain with those values. How to approach to that problem? We want that - at least our builds - are always shipped with generic entries. How Has This Been Tested? [ ] Generated rootfs with two mirrors that are fast in EU: CUSTOM_UBUNTU_MIRROR_PORTS="ftp.tu-chemnitz.de/pub/linux/ubuntu-ports/" CUSTOM_UBUNTU_MIRROR="mirrors.dotsrc.org/ubuntu/" Checklist: [x] My code follows the style guidelines of this project [x] I have performed a self-review of my own code [x] I have commented my code, particularly in hard-to-understand areas [ ] I have made corresponding changes to the documentation [ ] My changes generate no new warnings [ ] Any dependent changes have been merged and published in downstream modules View the full article

EVerest is a software project initiated by PIONIX GmbH, but now part of the Linux Foundation’s LFEnergy initiative, whose primary goal is to develop and maintain an open-source software stack for EV charging infrastructure. EVerest supports multiple standards and it will run on any device from AC home chargers to public DC charging stations. I noticed the EVerest project in an upcoming talk at the Embedded Open Source Summit 2023 entitled ” EVerest: Electric Vehicle Chargers With Open Hardware and Software” and whose abstract reads in part: You will learn how to build your own electric vehicle charger using open hardware designs in combination with the EVerest open-source software stack for EV charging infrastructure. Following a quick introduction to EV charging technology, with explanations of the standards, protocols, and complexities involved, the talk will go into a deep dive into how you can build your own AC charging station.

BLIKVM is an open-source KVM over IP software that helps you manage servers or workstations remotely regardless of the health of the target system, and currently working with Raspberry Pi CM4 hardware, a Raspberry Pi HAT, or a PCIe board, and a new model based on MangoPi’s Allwinner H616 CPU module is coming soon. We’ve previously written about the Raspberry Pi-based PiKVM DIY project, followed by the PiKVM v3 Raspberry Pi HAT from the same project, and now I can see there’s a CM4-based PiKVM V4 that was on Kickstarter last month and raised over $800,000… You’d think this kind of system would be rather a niche market, but there’s even demand to have a similar open-source project called BLIKVM offering many of the same features since it’s based on PiKVM, except for the option to use a PCIE card fitted with a CM4 module. Highlights of the BLIKVM project: [...] The post BLIKVM open-source KVM over IP works with Raspberry Pi CM4, Raspberry Pi HAT, PCIe card, and soon Allwinner H616 appeared first on CNX Software - Embedded Systems News.

PicoMQTT is a lightweight MQTT library for Arduino/PlatformIO optimized for ESP8266 and ESP32. It not only supports the MQTT Client mode like most existing solutions but also the MQTT Broker mode which transforms an ESP8266 or ESP32 board into an MQTT gateway replacing a Raspberry Pi board or an IoT gateway typically used for this task. The library follows MQTT 3.1.1 specification, supports the publishing and consuming of arbitrary-sized messages, can deliver thousands of messages per second, and supports easy integration with the ArduinoJson library to publish and consume JSON messages. MQTT Broker code example: [crayon-643e4a00948d8570550725/] There are some limitations to the implementation due to constrained resources in the ESP8266 and ESP32, notably: Client only supports MQTT QoS levels 0 and 1 Broker only supports MQTT QoS level 0, ignores will and retained messages. Another downside highlighted by the developer is that only ESP8266 and ESP32 boards are supported. Developer [...] The post PicoMQTT – An MQTT Client/Broker library for ESP8266 and ESP32 appeared first on CNX Software - Embedded Systems News. View the full article
