Some of the key features and improvements of Yocto Project 2.0 include: Added gcc 5.2 which is now the default compiler (gcc 4.8 and 4.9 are also provided) Updated linux-yocto kernel for qemu* and reference BSPs to version 4.1 Added basic support for Altera Nios II and Adapteva Epiphany Added tune files for Cavium ThunderX, Cavium Octeon, ARM Cortex-A17, Intel Quark X1000, and ARM vfpv3 and vfpv3d16 features Toaster Web UI improvements – Better performance and reliability; simplified setup; user-friendly layout; etc… wic image creation tool version 0.2.0 with bug fixed and new features, such as GPT partition tables, native tools, image compression, etc… Image generation adds support for qcow2, vdi (VirtualBox […]
Intel Quark D1000 Customer Reference Board and Intel System Studio for Microcontrollers
Intel unveiled Intel Quark D1000, D2000 and SE micro-controllers last week, with Intel Quark D1000 available now for $2.5 to $4 depending in quantities, and to my knowledge the first Intel MCU that can be considered ultra low power. I could not see a development board at the time, but Intel does have an Intel Quark D1000 Customer Reference Board with a familiar Arduino form factor. Intel Quark D1000 board specifications: MCU – Intel Quark D1000 32-bit CISC micro-controller @ 32 MHz Storage – 4MB SPI flash (Microchip ) Connectivity – Bluetooth LE radio, Wi-Fi (Inventek Systems Serial to Wifi module) Sensor – 3-axis accelerometer Expansion – Arduino compatible headers with GPIOs, I2C, SPI, UART, analog inputs, and 5V, 3.3V and GND. Debugging – mini USB port for programming and debugging; JTAG pins Power – 5V via mini USB port, or LiPo / Li-ion battery Dimensions – N/A Information about […]
Operys Process Explorer App Shows Android Processes in Your Computer’s Web Browser
Opersys is an Android and Embedded Linux company providing both development and training services, and they regularly attend conferences and release their training materials. The company has also developed a few Android apps to export the file system, the process list and info, and interaction between apps and Android system services exposed via Binder to your computer’s web browser. I found the most interesting app to be Process Explorer, so I gave it a try on Iocean M6752 smartphone. The application requires very little permissions to install, and it’s very simple to use. Simply tap on Start the service, and the app will provide the URL to browse the processes on your computer, in my case http://192.168.0.105:3000. The output is pretty useful, as you get much more information than you could get on your smartphone or tablet screen with CPU and memory usage, running time, logcat, etc… If you click […]
How to Use Nextion Serial Touchscreen Displays – Part 1: Standalone Mode
Itead Studio launched an Indiegogo campaign earlier this year for their Nextion TFT displays that can be connected to external board such as Arduino or Raspberry Pi via the serial interface, or even a standard computer provided you have a USB to TTL debug board. The campaign was successful with over 1,700 backers, and the company recently sent me two samples for review: a 2.4″ display and a 5″ display. In this post, I’ll look at the boards, and make a small standalone demo with Nextion Editor in Windows. Nextion NX3224T024 2.4″ Display The first item is a 2.4″ TFT display called NX3224T024_011N (non-touch) or NX3224T024_011R (Resistive touch) with 65536 color, 320×240 pixel resolution, LED backlight and up to 200nit brightness. It ships with a cable for the serial connection (5V, Tx, Rx, and GND). The back of the display features the serial connector, a micro SD used to load the […]
USB123 USBee AX PRO is a $10 USB Logic Analyzer Clone Compatible with Sigrok
A few months ago, I wrote about low cost logic analyzers selling for $75 and up, but yesterday, I stumbled upon an even cheaper, and admittedly lower end, logic analyzer called USB123 USBee AX PRO, allegedly a clone of the original USBee AX PRO minus the analog inputs, that sells for $9.99 on Dealextreme. [Update: It can also be bought for $5.60 on Aliexpress including shipping to most countries] USBee AX PRO specifications: Sampling rate – 24Msps Sample rate – 24MHz @ 8 channels Input voltage range: 0~5V Digital channel: 8 Low input voltage: < 0.8V; High input voltage: >1.4V Supported Protocols – SPI, IIC, UART, SMBus, I2S, CAN, Parallel, Custom, Search, Async, 1-Wite, PS/2 Dimensions – 5.4 cm x 2.7 cm x 1.8 cm Weight – 60 grams The tool ships with 10 Dupont cables and a USB cable to transfer data to your PC. DealExtreme also provides CDROM […]
ee203 Real-time Current Monitor Supports 1 μA to 1A Range, Outputs Data to Oscilloscope
Measuring current can be tricky, as I found out during my various attempts at measuring power consumption of TV boxes, as when the current gets too high, your measurement setup impedance may be too high (cables or multimeter), and the voltage delivered to the device under test too low for it too keep running, while accuracy may be an issue while measuring very low currents. EE Equipment ee203 Current Monitor solves some of these issues for people working on low power embedded systems as it can measure currents between 1 μA and 1A, and even output data to an oscilloscope to see real-time power consumption of the devices. Key features for ee203 current monitor: 6 Decades of Current Range: 1 μA – 1 A (2A fuse) No Range-Switching Interruptions or Delays Wide System Voltage Range 1.5V – 5.5V (12V Max) USB interface for calibration, control, and data logging View Current […]
Tronsmart Orion R68 RK3368 TV Box Firmware and Android SDK Released
Tronsmart Orion R68 is an Android 5.1 TV box powered by Rockchip RK3368 octa core ARM Cortex A53 processor with 1 or 2GB RAM, and 8 or 16GB eMMC flash depending on model, most probably based on Beelink i68 hardware.

How to Compare Systems Benchmarked with Phoronix Test Suite
Phoronix Test Suite is an open source benchmark for Linux, Solaris, Mac OS X, Windows & BSD operating systems, but in practice it’s mostly used for Linux OS since other benchmarks solutions are available in Windows, while choices are more limited in Linux. There are many benchmarks to choose from, and you can select the ones you want by running a “batch-benchmarks” from the command line. I’ve done so when testing performance of ODROID-XU3 Lite and Cubieboard4 boards in Ubuntu, and once the tests are completed, the results will be automatically uploaded to openbenchmarking.org. From there, it’s quite easy to compare recent results as you’ll get an “add to comparison” option on the site, and you can pick a few results. You can select a few systems, and then click on “Compare Results” to get a side-by-side comparison. If you want to compare your system to an existing system, you […]
