Using GPIOs on NanoPi NEO 2 Board with BakeBit Starter Kit

NanoPi NEO 2 is a tiny 64-bit ARM development board powered by Allwinner H5 processor. FriendlyELEC sent me a couple of NEO 2 samples together with their BakeBit Start Kit with a NanoHat and various modules via GPIOs, analog input or I2C. I’ve already tested both Armbian with Linux 4.11 and Ubuntu Core Qt with Linux 3.10, and ran a few benchmarks on NanoPi NEO 2. You would normally prefer to use the Armbian image with Linux mainline since it provided better performance, but at the time I was told GPIO support was not there. Configuring NanoPi NEO 2 board with BakeBit library So this week-end, when I decided to test GPIO support and BakeBit Starter Kit, I decided to follow this advice, especially nanopi-neo2-ubuntu-core-qte-sd4g-20170329.img.zip image is still the recommended one in the Wiki. So I went with that image. I’ll use Python examples from Bakebit library, but if you […]

Top Programming Languages & Operating Systems for the Internet of Things

The Eclipse foundation has recently done its IoT Developer Survey answered by 713 developers, where they asked IoT programming languages, cloud platforms, IoT operating systems, messaging protocols (MQTT, HTTP), IoT hardware architectures and more. The results have now been published. So let’s have a look at some of the slides, especially with regards to programming languages and operating systems bearing in mind that IoT is a general terms that may apply to sensors, gateways and the cloud, so the survey correctly separated languages for different segments of the IoT ecosystem. C and C++ are still the preferred languages for constrained devices, and developers are normally using more than one language as the total is well over 100%. IoT gateways are more powerful and resourceful (memory/storage) hardware, so it’s no surprise higher level languages like Java and Python join C and C++, with Java being the most used language with 40.8% […]

NAS Kit v1.2 Gets Support for NanoPi NEO 2, an UAS Capable USB to SATA Bridge, and an RTC Battery

Last month, FriendlyELEC launched a NAS Dock kit for NanoPi NEO board, but they’ll already removed it from their store. That’s because they have a new version NAS Dock v1.2 that also supports NanoPi NEO 2 with Gigabit Ethernet, replaces JMicron JM20329 by UAS capable JMicron JMS567 USB 3.0 to SATA bridge, and adds an RTC battery. The rest of NAS Dock Kit v1.2 specifications remain the same: 1-bay NAS Dock expansion board with JMicron JMS567 USB 3.0 to SATA bridge SATA connector for 2.5″ HDD drive Extra USB host port On/off switch, and dual color status LED Header to connect NanoPi NEO / NEO 2 board 12V DC power input Dimensions – 151 x 89.7 mm NS-120 aluminum enclosure (154 x 100 x 47.5 mm, 414 grams) Heatsink set for NanoPi NEO / NEO 2 4x M3 6mm screws, 8x M2.5 6 mm screws Four rubber pads Front and back covers […]

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 […]
