Qt/QML vs HTML5/AngularJS User Interfaces Showdown (Video)

We now live in a world where there’s a push for higher level programming languages either based on web technologies like HTML5 or JavaScript, or other interpreted languages such as Python, and lower level languages such as C, C++, or – maybe more understandably – Assembler are often avoided by newcomers. But there are advantages of using native code, as demonstrated by Sequality, a software engineering company, who asked a developer familiar with HTML and C++ to develop a demo of an embedded systems using HTML5 + AngularJS and Qt/QML. The developer had 160 hours to develop the user interface for each framework, and with the resulting demos running on a Raspberry Pi 3 board with Raspbian, it was found that the Qt/QML implementation delivered a more responsive and functional user interface compared to the HTML5 version which tended to lag, and lacked support for touchscreen and a software keyboard […]

YotaPhone 3 Dual Screen Smartphone to Launch for $360 and Up (in China)

Russia based Yota makes some unusual phones with dual display with a standard color front display, and an e-paper rear display that allows you to check the time without pressing a button, keeping displaying important information even when your battery is completely discharged, and more. The first Yotaphone was launched in December 2012, followed by a prettier and more powerful Yotaphone 2 in December 2014, but we’ve had to wait nearly three years for the company – with some fresh money and technical involvements from Chinese partners – to introduce YotaPhone 3 at the Russian Embassy in Beijing. The phone is powered by a Qualcomm Snapdragon 625 processor, and features a 5.5″ super AMOLED display on the front, and a 5.2″ E-Ink display on the back. Yotaphone 3 preliminary  (& partial) specifications: SoC – Qualcomm Snapdragon 625 octa-core Cortex A53 processor @ up to 2.0 GHz with Adreno 506 GPU System […]

SD Specifications 5.1 to Introduce App Performance Class (for Random I/O) & Logo

SD cards used to store media data only, for example photos and videos in your camera or smartphone, but with the introduction of “Adoptable Storage” in Android 6.0 you can now run apps directly on a micro SD card, and many development boards rely on (micro) SD card to run the full operating system. The difference is important, as with media storage, the raw sequential read and write speeds are the most important, as large files are created and accessed, but for apps and operating systems many small read and write operations such as databases access take place on the card, so random IO performance becomes much more important. So far, the SD card specifications would only report sequential performance with different classes, and for example for are often recommended to use “Class 10” SD cards on Raspberry Pi, which does not clearly indicates the random IO performance. SD Specifications […]

MIPI I3C Sensor Interface is a Faster, Better, Backward Compatible Update to I2C Protocol

I2C (Inter-Integrated Circuit) is one of the most commonly used serial bus for interfacing sensors and other chips, and use two signals (Clock and Data) to control up to 128 chips thanks to its 7-bi address scheme [Update: That’s the theory, as in practice it’s limited to a dozen devices max. due to capacitive load, see comments]. After announcing it was working of a new I3C standard in 2014, the MIPI Alliance has now formally introduced the MIPI I3C (Improved Inter Integrated Circuit) Standardized Sensor Interface, a backward compatible update to I2C with lower power consumption, and higher bitrate allowing it to be used for applications typically relying on SPI too. I3C offers four data transfer modes that, on maximum base clock of 12.5MHz, provide a raw bitrate of 12.5 Mbps in the baseline SDR default mode, and 25, 27.5 and 39.5 Mbps, respectively in the HDR modes. After excluding […]

Hisense A2 Android Smartphone Coming Soon with AMOLED and E-Ink displays

Yotaphone popularized dual display smartphones with your standard color display on the front panel complemented with an always-on E-Ink display on the rear panel that consumes less power, and even shows the latest screen update (e.g. your plane ticket) when the battery is depleted. The latest model – Yotaphone 2 – was launched in 2014, but for whatever there has not been an update since,  and companies appear to be clearing their stock with for example GearBest selling it for $119.99 shipped. However, even if the company never produces a Yotaphone 3, other have reproduced the design with the latest being Hisense A2 samrtphone whose specs have recently been published on TENAA (China equivalent of the FCC). Preliminary specifications for Hisense A2 smartphone: SoC – Qualcomm Snapdragon 430 octa-core processor @ 1.4 GHz with Adreno 505 GPU System Memory – 4GB LPDDR3 Storage – 64GB internal storage + micro SD […]

Realtek RTL8710AF (PADI IoT Stamp) vs Espressif ESP8266 (ESP-07) WiFi RF Performance Comparison

After I posted about PADI IoT Stamp IoT kit based on RTL8710AF ARM Cortex M3 WiSoC yesterday, I was soon asked whether I could compare the RF performance against ESP8266 modules like ESP-12. I don’t have any equipment to do this kind of test, except for some simple test like testing range with WiFi Analyzer app, but I remember Pine64 told me they had some comparison data a little while, and accepted to share their results. The test setup is comprised of Litepint IQ2010 multi-communication connectivity test system and PC software, as well as the device under test (DUT) with PADI IoT Stamp (version with u.FL antenna connector) and ESP-07 ESP8266 module as a u.FL connector is required to connect the test system. They’ve tested 802.11b, 802.11g, and 802.11n, but for IoT projects 802.11b is the most important as usually long range is more important than data rate. Test results […]
