Edge Impulse machine learning platform adds support for NVIDIA TAO Toolkit and Omniverse

Edge Impulse NVIDIA TAO Models

Edge Impulse machine learning platform for edge devices has released a new suite of tools developed on NVIDIA TAO Toolkit and Omniverse that brings new AI models to entry-level hardware based on Arm Cortex-A processors, Arm Cortex-M microcontrollers, or Arm Ethos-U NPUs. By combining Edge Impulse and NVIDIA TAO Toolkit, engineers can create computer vision models that can be deployed to edge-optimized hardware such as NXP I.MX RT1170, Alif E3, STMicro STM32H747AI, and Renesas CK-RA8D1. The Edge Impulse platform allows users to provide their own custom data with GPU-trained NVIDIA TAO models such as YOLO and RetinaNet, and optimize them for deployment on edge devices with or without AI accelerators. NVIDIA and Edge Impulse claim this new solution enables the deployment of large-scale NVIDIA models to Arm-based devices, and right now the following object detection and image classification tasks are available: RetinaNet, YOLOv3, YOLOv4, SSD, and image classification. You can […]

Arduino IDE 2.3 released with the Debug feature now considered stable

Arduino IDE 2.3 Debug Feature

Arduino IDE 2.3 has just been released with a range of bug fixes and improvements, but the main change is that the debug feature is not experimental anymore and is now considered stable. Bug fixes include addressing CVE-2023-4863 security flaw (See GitHub for related commits) and based on the wording used in the announcement it looks to be the only one… So the main news is that the Debug feature is now fully incorporated into the IDE. But what is it exactly? The new documentation website explains that Arduino CLI 0.9.0 and Arduino IDE 2.x support “sketch debugging” with openocd server. Arduino also explains it’s currently supported by Arduino boards based on the Mbed core including GIGA R1 WiFi, Portenta H7, Opta, Nano BLE, and Nano RP2040 Connect, and Renesas-based boards such as UNO R4 and Portenta C33 will get support very soon. The company also says they are working […]

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 […]

Arduino Cloud Editor update brings the classic Arduino IDE experience to your web browser

Arduino Cloud Editor

Arduino has updated the Arduino Cloud Editor – which started as Arduino Create several years ago – to bring the web-based code editor closer to the appearance and functionalities of the “classic” Arduino 2.0 IDE. Arduino says the Cloud Editor simplifies the getting started process without having to go through the setups or maintenance required by the Arduino IDE installed on your computer and you can access your sketches easily from the cloud wherever you are. Considering the Arduino Cloud Editor has been around for a few years what has changed exactly? First, the Cloud Editor and the Arduino IDE now have a unified design (sort of), although the way the company frames it is a bit abstract: Traditionally, Arduino Cloud had two separate editors: an embedded simple one and the full editor. Users have long awaited a unified editor that gets the best of each one. The new Cloud […]

ArduinoSimulator is an open-source Arduino Simulator that runs in your web browser

Arduino Simulator

Leonardo Russo’s ArduinoSimulator is an open-source Arduino Simulator written in JavaScript that runs code directly in your web browser and shows the serial output and digital/analog pins status for various Arduino boards namely Arduino UNO R3, MEGA1280, MEGA2560, and NANO V3. We previously covered the Wokwi simulator for ESP32. Arduino, and Raspberry Pi RP2040 that’s a great little tool for educators to emulate circuits and run code right in a web browser, and it even supports the ESP32-P4 wireless MCU although it’s yet to be released. While the simulators are written in JavaScript and open-source, the tool itself is not, and for instance, you can’t run a self-hosted instance of Wokwi or use it offline. The ArduinoSimulator is fully open-source and runs entirely from a web browser. It’s not quite as complex and full-featured as Wokwi, as you can’t build your own circuits, but you still have an area to […]

Watch ESP32’s GPIO status in real-time in a web browser

GPIOViewer ESP32 GPIO web browser

GPIOViewer is an open-source Arduino library allowing users to monitor the GPIO pins status of their ESP32 board in real-time in a web browser for troubleshooting or fun. It’s different than the Wokwi ESP32 simulator that works entirely in a web browser since the GPIOViewer library sends GPIO status data of the actual hardware over WiFi to display the pin status as they change in a page rendered in a web browser from a choice of popular ESP32 development boards. The GPIOViewer library relies on the ESPAsyncWebServer Async web server for ESP8266 and ESP32 and the AsyncTCP asynchronous TCP library for ESP32 microcontrollers. The first two must be manually downloaded and installed, and the latter can be installed directly from the Arduino IDE’s Library Manager by searching for it. GPIOViewer has a 50 KB footprint, works with digital, analog, and PWM, and supports various ESP32-VROOM-32 development boards, Olimex ESP32-EVB and […]

WCH RISC-V microcontrollers can now be programmed with the Arduino IDE

WCH RISC-V Arduino

WCH has launched some interesting RISC-V microcontrollers in the last year or so, including the “10 cents” CH32V003 RISC-V microcontroller with 2KB SRAM and 16KB flash or the CH32V307with more resources (up to 64KB SRAM and 256KB flash) and additional peripherals. So far they were programmable in C language using MounRiver IDE or an open-source toolchain, but WCH has now announced Arduino support for many of those RISC-V microcontrollers which should enable more people to get involved. The core library for CH32duino works with OpenOCD through WCH-LINKE hardware to download the firmware and debug WCH chips and a riscv-none-embed-gcc toolchain that supports custom RISC-V instructions (half-word and byte compression instruction extensions and hardware stack push/pop functions) found in WCH RISC-V microcontroller. The following evaluation kits are currently supported with ADC, DAC, USART, GPIO, EXTI, SysTick, I2C, and SPI peripherals: CH32V003F4P EVT board CH32V203G8U EVT board CH32X035G8U EVT board CH32V103R8T6_BLACK EVT […]

M5Stack releases local server implementations of UIFlow visual programming Web IDE

Visual programming local Web IDE

Visual programming is now a very popular method to teach programming to kids and M5Stack relies on UIFlow for their ESP32-based IoT development kit. Like most other companies, M5Stack provides either a Web IDE accessible from their server or a desktop program available for Windows, MacOS, or Linux, but the company has now released a local server implementation that allows users to run a Web IDE instance in their local network. The local server is available for Windows 11 x64, MacOS, Ubuntu 22.04, and Linux Arm (e.g. Raspberry Pi), so I downloaded the Ubuntu version to give it a try on my laptop. Somehow the Ubuntu release is full of Windows DLLs, but let’s ignore that for now, and the README.txt tells us to install one dependency and run the program as follows:

A window pops up letting us start or stop the server. It can be accessed with […]
