FreeRTOS Kernel Now Supports RISC-V Architecture

FreeRTOS RISC-V

FreeRTOS is one of the most popular operating systems found in embedded systems, and RISC-V open architecture is getting more and more traction, so it should come as no surprise that Amazon has now added RISC-V to their recently acquired FreeRTOS kernel. Jeff Barr, Chief Evangelist for AWS, explains both 32-bit and 64-bit RISC-V cores are supported, and several RISC-V boards are already supported out of the box: The kernel supports the RISC-V I profile (RV32I and RV64I) and can be extended to support any RISC-V microcontroller. It includes preconfigured examples for the OpenISA VEGAboard, QEMU emulator for SiFive’s HiFive board, and Antmicro’s Renode emulator for the Microchip M2GL025 Creative Board. There’s no a lot of information on Amazon announcement post, but FreeRTOS website has plenty of resources to help you get started with RISC-V. The page also lists some of the key features of the RISC-V port: Supports machine mode integer execution on 32-bit RISC-V cores only, but is …

NXP i.MX 8M Nano is a Power-optimized Arm Cortex-A53/M7 Processor

NXP i.MX 8M Nano

NXP introduced their first 14nm i.MX processor at Embedded World 2018 last year with i.MX 8 Mini processor equipped with up to four Cortex A53 cores clocked at 2.0 GHz and one real-time Cortex-M4 cores clocked at 400+ MHz, and optional 1080p video output and decoding/encoding. The company has now added another 14nm member to their i.MX 8M family with NXP i.MX 8M Nano family also featuring four Cortex-A53 cores at up to 1.5 GHz, but replacing the Cortex-M4 by a more powerful Cortex-M7 core clocked at up to 600 MHz. The processor is also power-optimized for less than 2W total dynamic power (TDP) and sub-watt in many IoT edge applications. NXP i.MX 8M Nano key features and specifications: Application cores – One to four Arm Cortex-A53 cores up to 1.5 GHz per core; 32KB L1-I Cache/ 32 KB L1-D Cache; 512 KB L2 Cache Real-time core – Arm Cortex-M7 at speeds of up to 600 MHz; 16 KB L1-I …

Minnow Server is a Secure Web Server for Microcontrollers

Minnow Server Secure Websocket

Many embedded systems have a limited amount of memory, which would normally run programs with smaller footprints than on desktops or servers. For example, nginx and Apache2 are the common web servers, but on hardware with limited memory, smaller footprint web servers may be required, so that’s why I wrote a list of web servers for embedded systems running Linux/uClinux many years ago. But now, even platforms based on microcontrollers often need to run web server usually for configuration. We’ve already shown how to use Arduino to serve a simple web page and did the same in Getting Started with NodeMCU Board Powered by ESP8266 WiSoC but using Lua programming language instead. It may be more convenient to run a proper web server however, as it’s easier to change the interface, and we previously covered MicroWebSrv lightweight web server that works on platforms running MicroPython such as Pycom boards. Real Time Logic offers another open source alternative with their Minnow Server …

TTGO T-Camera ESP32 Camera Board Comes with OLED Display, Sensors

TTGO T-Camera ESP32 OLED Display

ESP32 is now being used for AI workloads such as face detection with camera boards like ESP32-CAM, or the upcoming ESP-EYE board from Espressif Systems themselves, combined with ESP-WHO face detection and recognition framework. The two aforementioned board require you to use a phone to vizualize the results, unless you blink some LEDs or connect your own display. But the just released TTGO T-Camera board includes a 128×64 OLED display which should allow you to display face detection and/or recognition results, as well as a BME280 environmental sensor, a PIR sensor, and an optional fisheye lens.
