ARM Cortex-M7 in STM32 F7 STMicroelectronics, IS2T brings MicroEJ Java apps store for embedded market

Posted by Charbax – February 27, 2015

STMicroelectronics launches STM32 F7 series of very high performance Microcontroller Units based on the ARM Cortex-M7 core. The STM32 F7 devices are the world’s first ARM Cortex-M7 based 32-bit microcontrollers, improving on the benchmark performance. Taking advantage of ST’s ART Accelerator as well as an L1 cache, the STM32 F7 devices deliver the maximum theoretical performance of the Cortex-M7 no matter whether code is executed from embedded Flash or external Memory: 1000 CoreMark/428 DMIPS at 200 MHz fCPU.

Demonstrated running on the STM32 F7, IS2T MicroEJ SDK enables embedded Java development for any MCU and MPU, from the smallest ARM Cortex-M0+ to the newest Cortex-M7 and beyond. The embedded Java platform includes IS2T Java Virtual Machine (footprint: 28KB of RAM, 1.5KB of RAM) and IS2T libraries for IoT, GUI and communication applications. Boot time to first line of Java main is 2ms on a Cortex-M4@120MHz.

IoT solutions includes TPC/IP, Wifi, MQTT, Websockets, HTTP, JSON, XML, COAP... protocols. GUI solutions includes a full set of widgets, drawing, motions, anti-aliased... libraries - typical animations at 60FPS with less than 10% CPU load. Full Java applications run on MCU starting from 256KB of flash.

The MicroEJ demo running on STM32F7 device shows the Waddapps store connection, an online store of embedded applications that can be downloaded to the STM32F7 through any link (e.g. ethernet, Wifi, Bluetooth). Apps are downloaded, installed, started, stopped, uninstalled without reset - same as smartphone users would typically do with an Apps Store.

Secure IoT for the future: Thread stack mbed OS on ARM Cortex-M using Atmel 802.15.4 radios

Posted by Charbax – February 25, 2015

Seppo Takalo, Senior software engineer, talks about the work happening at the Thread group to enable secure and reliable Internet of Things, formed from companies who work with 802.15.4 based mesh networking components. The goal is to provide a standard for Secure, Robust, self healing, Native IPv6 based mesh networking that runs on top of 6LoWPAN and uses standard 802.15.4 radios.

ARM mbed OS platform for Internet of Things

Posted by Charbax – January 28, 2015

ARM talks sensors to servers demonstrations, ways to implement Internet of Things, using the mbed development boards with Arduino headers, the Arduino Shield with a low-power WiFi, doing custom sensor modules with temperature, microphone, ultra-sonic and motion sensors, stacking them up to do sensor nodes, then putting them around the booth to show a dashboard of things happening at the booth hosted on an AppliedMicro X-Gene server.

Greenwave Systems at IDTechEx IoT Applications conference

Posted by Charbax – January 25, 2015

Greenwave Systems is a global Internet of Things (IoT) software and services company. Jim Hunter is the Chief Scientist and Technology Evangelist at Greenwave Systems. Greenwave is a profitable mid size start-up (215 people) with offices in Irvine, Copenhagen, Singapore and South Korea, that enables device manufacturers, service providers, utilities, retail channels and other enterprises to realize the promise of IoT through their devices and services. Jim was speaking at the IDTechEx IoT Applications conference, along with his colleague Nate Williams on the business challenges of IoT. In two separate sessions, they explained how Greenwave helps customers such as Verizon, TCP lighting, & E.ON Energy to design, build, manufacture, deliver, manage, maintain and support IoT devices - ranging from content to control, enabled by Greenwave's Axon software platform.

World’s lowest power: Atmel SMART SAM L21 ARM Cortex-M0+, Andreas Eieland

Posted by Charbax – January 22, 2015

This is the lowest power consuming 32bit ARM Processor in the world based on ARM Cortex-M0+ for wearables (can be with basic touch) and for the sensor networks in the Internet of Things, can run up to more than a decade on a battery. The new Ultra low power Atmel | SMART SAM L21 based on the ARM Cortex-M0+ Core uses less than a third of the power consumption of competitive solutions and can run in active mode down to 35uA/MHz and retain 32kB of Flash and run a real time clock at 900nA. In this demo the SAM L21 is powered from the heat of a hand through a Peltier Element, this is enough energy to modulate a music file and transmit it with AM modulation at 1MHz to the nearby radio receiver. This demo shows that the SAM L21 is truly unique in supporting ultra-low power consumption in active mode without having to limit Flash or SRAM size, it is perfect for IoT and other battery powered applications where large embedded memories are needed.

Atmel Corporation discuss Internet of Things

Posted by Charbax – January 21, 2015

Atmel has over 40,000 customers of its Microcontroller units - companies embedding MCUs to make devices powering the Internet of Things. For example, Arduino devices use Atmel MCUs. The Arduino WIFI shield includes a new Atmel MCU processor built from the ground up for WIFI running on batteries. Atmel is launching the lowest power 32bit ARM Cortex-M0+ processor (see their press release here) and Atmel is also launching the highest performance ARM Cortex-M7 Microcontroler (see press release here)

YoBox labels: Personal RFID/NFC/QR-code Storage Management

Posted by Charbax – January 18, 2015

YoBox labels help organize ones personal storage (now on Kickstarter!). Each YoBox label is uniquely numbered with NFC and QR code. Users take pictures or/and write keywords to describe everything that is stored in each storage box. YoBox labels are color coded to help easily identify each box in the storage room. The idea is to never go through endless boxes to find something in ones personal storage again! This is industrial strength personal storage management on mobile, the YoBox app is compatible with both Android and iOS. Battery free, RFID-enabled YoBox label can be read by NFC reader built into many Android smartphones. For iPhones and other phones not yet equipped with NFC, users can scan the QR code on the YoBox label to retrieve the info.

Read more about it on Kickstarter campaign still going on for 12 more days!

Hisense is a company based in Qingdao China that makes home-used appliances like TVs, refrigerators and other. Here at Shenzhen Electronics Fair they are showing their latest Smart TVs. They are launching their new display technology called ULED. Hisense use their scene engine technology, the chinese company suggest to have the same picture quality/performance like an OLED TV device. They call it ULED and its basically a LCD-LED backlight display with some improvements to match the OLED display technology. Hisense's TVs have their own software and hardware built-in to make the TV smart. The software is some kind of customized operating system similar to android or built over Linux that offers many potentials for home entertainment. Their TVs come in different diagonal sizes and different colors. Some have touchscreen or hand gestures control options and soon a curved TV will be available from Hisense.
