Microsoft open-sources Eclipse ThreadX real-time operating system

Eclipse ThreadX components

Microsoft will soon open-source Eclipse ThreadX real-time operating system that has been deployed on more than 12 billion embedded devices worldwide since its first release in 1997 and, for instance, it is found in Broadcom processors powering Raspberry Pi SBCs. ThreadX was a commercial, safety-certified real-time operating system developed Express Logic which was acquired by Microsoft in 2019 and renamed to Azure RTOS. Last year, Microsoft decided to start the process to fully open-source Azure RTOS under an MIT license and managed by the Eclipse Foundation. Hence its new name: “Eclipse ThreadX“. The Eclipse ThreadX project is not simply comprised of the RTOS itself, but also includes other components: ThreadX – Real-time operating system (RTOS) designed for deeply embedded applications NetX Duo – Industrial-grade TCP/IP network stack designed for deeply embedded real-time and IoT applications FileX – FAT-compatible file system integrated with ThreadX kernel GUIX – Embedded graphical user interface […]

The Eclipse Oniro Project aims to deliver consumer & IoT software that works across multiple platforms

Eclipse Oniro Project

Several of the embedded talks at FOSDEM 2022 mention the “Eclipse Oniro Project”. I had never heard about that project from the Eclipse Foundation, so let’s see how they describe it: Oniro is an Eclipse Foundation project focused on the development of a distributed open source operating system for consumer devices, regardless of the brand, model, make. Oniro is a compatible implementation for the global market of OpenHarmony, an open source operating system specified and hosted by the OpenAtom Foundation. Designed with modularity in mind, Oniro offers greater levels of flexibility and application portability across the broad spectrum of consumer and IoT devices — from tiny embedded sensors and actuators, to feature rich smart appliances and mobile companions. As a distributed and reusable collection of open source building blocks, Oniro enables compatibility with other open source technologies and ecosystems. Through close collaboration with projects and foundations such as OpenHarmony from […]

Polos GD32V Alef is a Tiny RISC-V MCU Board Selling for $3

Polos GD32V Alef

We first found out about GigaDevice GD32V 32-bit RISC-V MCU last summer, as an update/alternative to the earlier STM32 compatible GD32 Arm Cortex-M3 microcontroller from the company with higher performance and lower power consumption, while keeping the price identical. The first low-cost GD32V development board we covered was Longan Nano going for $5 with an OLED display and an acrylic case. If you don’t need either or want to access all pins from the 48-pin MCU,  you can now order an even cheaper GD32V RISC-V MCU board with Polos GD32V Alef going for $2.99 on Analoglamb website. Polos GD32V Alef board specifications: MCU – Gigadevice GD32VF103CBT6 32-bit RISC-V (rv32imac) microcontroller @ 108 MHz with 128KB Flash, 32KB SRAM USB – 1x micro USB OTG port for power and programming Expansion – 52 through holes (2.54mm pitch) exposing all pins from the MCU including 3x USART, 2x I2C, 3x SPI, 2x […]

Eclipse IoT Survey Report Reveals Arm & Linux Dominate, Security Concerns

Constrained devices Arm IoT

The Eclipse IoT Working Group has just released a report asking the global IoT developer community to share their perceptions, requirements, and priorities. And with over 1,700 individuals taking the survey between February and March 2019, the key findings are interesting: IoT drives real-world, commercial outcomes today. 65% of respondents are currently working on IoT projects professionally or will be in the next 18 months. IoT developers mostly use C, C++, Java, JavaScript, and Python AWS, Azure, and GCP are the leading IoT cloud platforms Top three industry focus areas remain the same as last year: IoT Platforms, Home Automation, and Industrial Automation / IIoT. MQTT remains the dominant IoT communication protocol leveraged by developers The Eclipse Desktop IDE is the leading IDE for building IoT applications The last point may be slightly biased because the survey was done by the Eclipse IoT Working Group, so most respondents were already […]
