Samsung Unveils Tizen 4.0 with .NET Framework, Low End IoT Devices Support

We’ve already seen the announcement of Samsung ARTIK 053 WiFi module with Tizen RT this morning, but it appears that Tizen RT (Real Time) is part of a Tizen 4.0 that will add support to IoT devices, as well as introduce changes from the developers’ perspective. Samsung Electronics talked a bit more about Tizen Next (Tizen 4.0) at the Tizen Developer Conference (TDC) 2017 taking in place on May 16-17 in San Francisco. Few details are provided in the press released, but we could learn that “the Tizen 4.0 platform has been extended to Tizen RT (Real-Time) to involve high-end products such as TVs and mobile devices as well as low-end products such as thermostats, scales, bulbs, and more”. Tizen RT page explains that the real-time operating system is designed to run on Cortex M/R MCU with less than 2 MB RAM, less than 16 MB flash, and consists of […]

HTC U11 Android Smartphone Adds “Edge Sense” Squeeze Input, Ranks Best at DxOMark Mobile Camera Benchmark

We’ve come so far in the smartphone market that most hardware releases are rather boring with a processor a little faster, maybe a higher resolution screen and so on, without real exciting innovations. HTC U11 does change that somewhat as the smartphone allows to interaction by squeezing the edges for example to quickly take a picture. The company calls that “Edge Sense” technology. HTC U11 specifications: SoC – Qualcomm Snapdragon 835 octa-core processor @ up to 2.45 GHz System Memory – 4GB / 6GB RAM Storage – 64GB / 128GB flash, micro SD slot up to 2TB (shared with SIM2 slot), flex storage (aka adoptable) supported Display – 5.5″ Quad HD (2560 x 1440 pixels) Super LCD; 3D Corning Gorilla Glass 5 Cellular Connectivity Dual nano SIM 2G/2.5G – GSM/GPRS/EDGE @ 850/900/1800/1900 MHz 3G – UMTS @ 800/900/1900/2100 (B5/B8/B2/B1), HSDPA 42, HSUPA 5.76 4G LTE – Cat 15 LTE up […]

MCUBoot is an Open Source Secure Bootloader for IoT / MCUs

Bootloaders takes care of the initial boot sequence on the hardware before the operating system takes over. For example, U-boot is often used in embedded systems as the bootloader before starting the main operating systems such as Linux or FreeBSD. MCUBoot is also a bootloader, but it targets the IoT, here referring to MCU based systems with limited memory and storage capacity, and is born out of work on Apache Mynewt OS, when developers decided to develop the bootloader separately from the operating system. MCUBoot is designed to run on small & low cost systems running on MCU with ~512 KB flash, ~256 KB RAM, and currently supports Zephyr OS and Mynewt, with support for other RTOS also considered. Due to constraint the bootloader uses minimal features with a flash driver, a single thread, and crypto services. The project also aims at solving security and field firmware updates. To address the […]

EduExo DIY Robotic Exoskeleton Kit is Arduino Powered, 3D Printable, Designed for STEM Education (Crowdfunding)

Robotic exoskeletons are used for medical purposes such as helping with the rehabilitation of stroke patients, or enable paraplegics to walk again, as well as in the work place to assist people lifting heavy objects. While it’s possible to learn about the theory about exoskeleton technology, practical experience may help grasping all concepts better. However, there are not many courses available, and exoskeletons are usually expensive, so Volker Bartenbach, PhD at ETH in Zürich, has decided to created EduExo robotic exoskeleton kit for education purpose. The EduExo hardware is based on off-the-shelf components like an Arduino UNO board, a motor, and a force sensor, as well as a rigid exoskeleton structure and cuff interfaces. The latter is optional as you can get the kit without it, and will instead receive the STL files to 3D print the parts yourself. There’s also a handbook to help you get started in several […]

Helios4 Personal Cloud DIY NAS Supports 3.5″ Hard Drives, RAID, and More (Crowdfunding)

A few months ago, we covered GnuBee Personal Cloud 1, a NAS that runs on open source software, and that supports up to six 2.5″ SATA drives. The crowdfunding has been successful – after lowering the funding target -, and backers should hopefully get the NAS right after summer. But at the time, some people complained about the memory capacity (512MB), the lack of support for 3.5″ drives, and a few other items. A new project called “Helios4 Personal Cloud” addresses many of those concerns. It comes with 1 to 2GB RAM, enclosure supporting four 3.5″ drives, supports RAID, and is powered by Marvell ARMADA 388 processor that has been specifically designed for this type of application. Helios4 NAS specifications: SoC – Marvell ARMADA 388 dual core Cortex A9 processor @ up to 1.866 GHz with RAID5/6 acceleration engines, security acceleration engines, etc… System Memory – 1 or 2 GB […]

Think Silicon Ultra Low Power NEMA GPUs are Designed for Wearables and IoT Applications

When you have to purchase a wearable device, let’s say a smartwatch or fitness tracker, you have to make trade offs between user interface and battery life. For example, a fitness tracker such as Xiaomi Mi Band 2 will last about 2 weeks per charge with a limited display, while Android smartwatches with a much better interface need to be recharged every 1 or 2 days. Think Silicon aims to improve battery life of the devices with nicer user interfaces thanks to their ultra-low power NEMA 2D, 3D, and GP GPU that can be integrated into SoCs with ARM Cortex-M and Cortex-A cores. The company has three family of GPUs: NEMA|p pico 2D GPU with one core 4bpp framebuffer, 6bpp texture with/out alpha Fill Rate – 1pixel/cycle Silicon Area – 0.07 mm2 with 28nm process Power Consumption – leakage power GPU consumption of 0.06mW; with compression (TSFSc): 0.03 mW NEMA|t […]
