Qt for MCUs 1.1 Adds Support for more STM32 and NXP i.MX RT Boards, FreeRTOS

Qt for MCUs 1.1 Installer

The first stable version of Qt for MCUs was released in August 2019 in order to bring Qt graphical toolkit to microcontrollers such as STMicro STM32F7,  Renesas RH850, or NXP i.MX RT1050.   Qt for MCUs would run bare metal on supported boards, and software engineers would develop graphical interface using QML and C++. Qt for MCUs 1.1 has just been released with the addition of more STM32 and i.MX RT boards, support for FreeRTOS real-time operating system, and more. Qt for MCUs 1.1 highlights: Five new supported boards:  NXP i.MX RT 1064 EVK, STM32 H750B-DK, STM32 F469i-disco, STM32 L4R9i-disco, and STM32 L4R9i-eval Asset management Optional PNG compressions for assets to lower storage footprint Option to read data directly from flash memory for lower RAM consumption, or copy to RAM for better performance, at the cost of higher RAM consumption. FreeRTOS support (technology preview) to run background tasks without blocking the […]

ESP RainMaker Eases Cloud Integration & Mobile App Development for ESP32-S2 SoC

ESP RainMaker Android App

Espressif Systems is well-known for its low-cost, well-supported WiFI and Bluetooth SoC for IoT products and projects. But in recent years, the company has also come up with application-specific development boards and corresponding software frameworks to help customer develop their own. Those boards include ESP32-LyraTD-MSC for smart audio applications, or for ESP32-S2-Kaluga-1 multimedia applications using display and camera. The company is now offering another solution to help makers integrate ESP32-S2 secure WiSoC with the cloud and create a mobile app. Meet ESP RainMaker. Specifically, ESP RainMaker provides four main components:: Device Agent SDK to perform network provisioning, OTA updates and facilitate communication with the cloud. Based on the ESP-IDF SDK. Amazon’s AWS powered Transparent Cloud Middleware makes the device’s attributes accessible to the user’s phone applications or other third-party services via RESTful APIs. iOS/Android phone apps to configure and manage the connected device. The apps are “self-adapting”, meaning they can […]

Bluetera II is a motion-enabled IoT development board that supports protocol buffers (Crowdfunding)

Bluetera II

Tensor Iotera Group (TIG), an Israeli based technology company, has launched a powerful IoT development board featuring motion sensing called Bluetera II and supporting Google Protocol buffers. Bluetera II came from the idea that developing an IoT application shouldn’t be complicated. Hardware is hard, and scaling for manufacturing might also be more daunting than initially anticipated. So instead of going through those troubles, why don’t you go the route of something that works, and most importantly, is scalable, as TIG is advocating with their Bluetera IoT development platform. Bluetera II is the 2nd generation of this IoT platform. The Bluetera II board is equipped with a 9-axis motion sensor, Bluetooth 5 enabled Nordic nRF52840 SoC core, which features an Arm Cortex-M4 FPU, with 1MB of Flash, 256KB of RAM, and lastly, an SDK based on Google’s Protocol Buffer (protobuf) technology. The device can function as a BLE Central (Master) and […]

20TB HAMR Hard Drives Coming in 2020, up to 80TB Drives Expected in a Few Years

Seagate HAMR Hard Drives

We first wrote about HAMR technology in 2017. HAMR stands for “Heat-Assisted Magnetic Recording” and aims at increasing data density in order for manufacturers to cram even more bytes into 2.5″ and 3.5″ drives. You can learn more about HARM technology in your previous article. At the time, Seagate had built over 40,000 HAMR drives for internal testing, and expected volume shipments of 20TB+ drives in 2019. There have been some delays, but Seagate recently announced their first formatted and fully functioning 3.5″ 16TB enterprise hard drive platform based on the technology. Bear in mind that those are only internal test units, and will not be brought to market in this configuration. Instead, the company plans to start selling its first HAMR drives with at least 20TB storage capacity later this year. The new drives behave just like existing PMR drives and are just plug-and-play in existing systems with SATA […]

Realtek RTL8720DN Dual-Band WiFi & Bluetooth 5.0 IoT Modules Sell for $4 and Up

BW16 RTL8720DN Dual-band WiFi & Bluetooth Module

There are plenty of 2.4 GHz WiFi modules for IoT project based on processors ranging from Espressif Systems ESP8266 to TI CC3200, or Realtek RTL8710. Some others add Bluetooth 4.2/5.0 such as Espressif Systems ESP32, but it’s much harder to find solutions with dual-band WiFi especially if you have a tight budget for your project or product.

GreenWaves GAP9 IoT Application Processor Enables AI on Coin-cell Powered Devices

GAPuino Board

GreenWaves Technologies GAP8 multi-core RISC-V microcontroller was introduced last year for artificial intelligence (AI) at the edge at ultra-low power consumption. GAP8 AIoT SoC was shown to perform inference at 3.7mA against 60mA for the same workload on STM32F7 Arm Cortex-M7 MCU. The company has now expanded its GAP IoT application processor family with GAP9 that delivers five times lower power consumption compared to GAP8 microcontroller while enabling inference on neural networks 10 times larger. Greenwaves GAP9 will bring machine learning and signal processing capabilities to (coin cell) battery operated or energy harvesting devices such as IoT sensors in consumer and industrial markets, wearables, smart building, smart farming and so on. GAP9 is said to combine architectural enhancements with Global Foundries 22nm FDX process to achieve a peak cluster memory bandwidth of 41.6 GB/sec and up to 50 GOPS compute power while consuming only 50mW. The increased memory bandwidth (20x […]
