STM32Cube.AI Developer Cloud generates AI workloads for STM32 microcontrollers

STM32Cube.AI developer cloud

STMicroelectronics has just announced the STM32Cube.AI Developer Cloud opening access to a suite of online AI development tools for the STM32 microcontrollers (MCUs) allowing developers to generate, optimize, and benchmark AI working on the company’s 32-bit Arm microcontrollers. The company sus the STM32Cube.AI Developer Cloud is based on the existing STM32Cube.AI ecosystem of desktop tools with the added benefit of being able to remotely benchmark models on STM32 hardware through the cloud in order to save on workload and cost. Some of the highlights of the online tools include: An online interface to generate optimized C-code for STM32 microcontrollers without requiring prior software installation. Access to the STM32 model zoo, a repository of trainable deep-learning models and demos. It currently features human motion sensing for activity recognition and tracking, computer vision for image classification or object detection, audio event detection for audio classification, and more. You’ll find those on GitHub […]

Low-cost STM32C0 32-bit microcontroller aims to displace 8-bit MCUs

STM32C0 block diagram

8-bit MCUs are still found in many designs, but with the new low-cost 48MHz STM32C0 32-bit Arm Cortex-M0+ microcontroller, STMicroelectronics aims to displace 8-bit microcontrollers thanks to “a limited impact on the cost structure” and the improved support provided by the STM32 ecosystem.

Meadow F7v2 Feather STM32F7 MCU board supports .NET, C# programing

STM32 Microsoft .Net

Wilderness Labs Meadow F7v2 Feather is an STM32F7 Arm Cortex-M7 development board following the Adafruit Feather form factor and programmable with C# through a lightweight implementation of the .NET framework. We had previously seen the .NET Framework running on Android and Linux thanks to Xamarin’s Mono, but I don’t think I had ever a microcontroller-class board supporting the .NET framework and C# programming. But that’s exactly what the Meadow F7v2 Feather does. Meadow F7v2 Feather specifications: MCU – STMicro STM32F7 Arm Cortex-M7 microcontroller @ 216 MHz with 2D graphics and JPEG accelerators Memory – 32MB RAM Storage – 64MB flash Connectivity – 2.4 GHz WiFi and BLE (ESP32) with onboard and external u.FL antennas USB – 1x Micro USB port for power and programming Expansion with through and castellated holes with up to 25x GPIO, 12x PWM, 6x analog inputs, 2x DAC, I2C, I2S input/output, SPI, UART, CAN Bus Misc […]

Air32F103 is a clone of STM32F103 clocked at up to 216 MHz

AIR32F103 development board

Air32F103 is yet another clone of the STM32F103 microcontroller that can be faster if needed with a clock of up to 216 MHz instead of 72 MHz for the original STMicro STM32 Arm Cortex-M3 microcontroller. The first SKU of the family is the Air32F103CBT6 whose peripherals and hardware design are compatible with equivalent STM32F103CBT6 parts and offered with 32KB RAM and 128KB flash. There’s also a Bluepill-like development board, but with a different pinout, made by LuatOS. Documentation for the board and microcontroller can be found in a Wiki including the MCU datasheet that indicates models with 256KB flash and 64KB SRAM (Air32F103CCT6) and 96KB SRAM (Air32F103RPT6). Since the wiki is in Chinese only, you may want to head over a post in English on Chowdera to learn how to get started with the Keil IDE using code hosted on Gitee. The chip and board were also spotted on EEVBlog […]

Arduino Opta is a micro PLC for industrial IoT applications

Arduino Opta micro PLC

Arduino has recently announced the Opta micro PLC with industrial IoT capabilities adding yet another solution to the Arduino Pro family. Arduino used to focus on the hobbyist crowd, but with the launch of the Arduino Pro family in 2020 starting with the Portenta H7 board, the company switched its main focus to the more profitable enterprise market. Since then they’ve launched several other boards designed in-house, and last year started collaborating with the introduction of the Arduino WisGate Edge LoRaWAN gateways based on RAKwireless hardware. The Arduino Opta is another one of those collaborations as it was designed together with Finder, who calls their devices PLR (Programmable Logic Relays). Arduino Opta key features and specifications: MCU – STMicroelectronics STM32H747XI microcontroller with 1x Arm Cortex-M7 core up to 480 MHz, 1x Arm Cortex-M4 core up to 240 MHz, 2MB flash, 1MB SRAM (as found in all Portenta H7 boards, and […]

Arduino Lab for MicroPython – An experimental cross-platform MicroPython IDE for Arduino boards

Arduino Lab for MicroPython

Arduino boards have traditionally been programmed with C-like language in the Arduino IDE, but with the Arduino Lab for MicroPython, Arduino added MicroPython to several official Arduino boards. In the words of the Arduino Team, “not an official product yet, an experimental tool”, but I would not be surprised if it becomes an official IDE eventually as the company collaborated with Damien George, the creator of MicroPython, to port the official the virtual machine to a number of Arduino products, and Murilo Polese to develop the Arduino Lab for MicroPython cross-platform IDE for MicroPython.   The IDE looks familiar… Oh yes, I see it now, it’s basically the Arduino IDE, but for MicroPython… 😉  and many of the same features including supporting connection with a board, code upload, file transfer, plus a Python-specific interactive REPL shell. Arduino Lab for MicroPython features so far: MicroPython’s Read Eval Print Loop (REPL) Enter […]
