Sigrok and Pulseview in Ubuntu 14.04 with UNI-T UT61E Digital Multimeter

A couple of months ago, I received a new digital multimeter UNI-T UT61E that can send data to a computer via a serial cable, and allows you draw some nice charts. I’ve already done that in Windows 7 with the provided tools, and reported on the power consumption of some Chinese Android TV boxes. However, since I use Ubuntu 14.04 as my main operating system, Linux based tools would be more convenient, and open source sigrok-cli command line client and its graphical interface pulseview are supposed to support UT61E DMM, so I had to give it a try. A Quick Look at UNI-T UT61 Digital Multimeter Before going into Sigrok, I’ll quickly show what the multimeter received from DealExtreme . It took longer than expected to ship because of of  included 9V battery, and at the first shipping attempt it was returned to DX, but after 8 weeks or so, […]

DonglePi is a USB Dongle with a Raspberry Pi Header for your PC

While the newer Raspberry Pi A+, B+ and B2 boards feature the new 40-pin connector, the Raspberry Pi boards Model A and B have a 26-pin expansion header, but both are use to access GPIOs, UART, SPI, I2C and interface with external hardware, and many add-ons boards have been developed for the Raspberry Pi. But what if you’d like to use R-Pi add-ons board on your PC, or instead you are developing your own add-on board, but would like to do so directly on your PC for convenience? DonglePi is the answer. It’s a small USB dongle with Atmel SAMD21 MCU and a 26-pin Raspberry Pi compatible header, that you could use connect to your Android/Linux/Windows PC to play with GPIO, I2C, SPI, Serial, PWM just like on a Raspberry Pi, and using RPi/GPIO or smbus Python libraries for programming. The project is still in development, and so far most […]

Xilinx Introduces Zynq UltraScale+ MPSoC with Cortex A53 & R5 Cores, Ultrascale FPGA

Xilinx Zynq-7000 dual core Cortex A9 + FPGA SoC family was announced in 2012, and provides a wide range of SoC with features and price range, and led to low cost ARM + FPGA such as ZedBoard, and more recently Parallela and MYiR Z-Turn boards. The company unveiled its successor with Zynq UltraScale+ MPSoC providing five times more performance per watt, with four ARM Cortex A53 cores, two ARM Cortex R5 real-time MCU cores, a Mali-400MP GPU, an UltraScale FPGA fabric manufactured with 16nm FinFET+ process. There are two main sub-families in Zynq Ultrascale+ MPSoC for “smarter control & vision”, and “smarter network”. Both share the same processing systems (CPU, GPU, MCU, Peripherals, Security), but the networking family has beefier FPGAs,  and lacks the H.264/H.265 video processing unit found in the control & vision version: Processing Systems Processor – Quad ARM Cortex A53 MPCore up to 1.3GHz Real-time Processor – […]

Linaro 15.02 Release with Linux 3.19 and Android 5.0

Linaro 15.02 has just been released with Linux 3.19 (baseline), Linux 3.10.68 and 3.14.34 (LSK), Android 5.0.2, and Ubuntu Linaro Utopic. Listed changes for Linux Linaro are exactly the same as last month, except they’ve used Linux 3.9 release. Power management tools have been added to their AOSP build, and some work has been done for Android 5.0 on the new Hikey board. Here are the highlights of this release: Linux Linaro 3.19-2015.02 GATOR topic: version 5.20.1 updated integration-linaro-vexpress64 topic by ARM LT (FVP Base and Foundation models, and Juno support) updated topic from Qualcomm LT (ifc6410 board support) updated topic from HiSilicon LT (Hi36xx, HiP04, and X5HD2 families support) updated LLVM topic (the community llvmlinux-latest branch) included ILP32 patch set v3 rebased onto 3.19. Initial tests using syscalls LTP tests done. When using ILP32 userland, a few tests have to be skipped (msgctl07, msgrcv0[1-7], msgsnd01) to avoid the stalls, […]

GroBotz Interactive Robot Project is Made of Easy to Assemble Smart Blocks (Crowdfunding)

GroBotz makes me think of Lego applied to robotics. The project consists of modules such as motors, sensors, buttons, switches, or cameras that snap together in order to create a robot on wheels, games, toys, a musical instrument, or whatever idea you may have, and the hardware is then programmed using a graphical user interface. A Raspberry Pi board is used for the brain of the robot, and Microchip PIC MCUs for the smart blocks. The software is programmed in C# using Xamarin, the user interface is based on Unity, OpenCV is used for image processing, and during development a plastic part where printed with Makerbot, and schematics and PCB layout designed with CadSoft EAGLE. The company has now come up with a number of modules as shown in the picture below. Your robot can then be controlled over Wi-Fi with GroBotz app which works on Windows, Mac OS, iOs, […]
