Reader O f f er Deterministic motor control with FPGAs This month, Microsemi is giving away two SmartFusion2 dual-axis motor control starter kits, worth $599 each, for EETimes Europe’s readers to win.The kit will let you try out Microsemi’s deterministic motor control solution, compliant with industry coding standards for developing safe and reliable software for embedded applications. The solution has algorithms like Sensorless - FOC, FOC with HALL, FOC with Encoder and FOC with Resolver for PMSM/BLDC motors. The position control algorithm of stepper motor supports up to 1024 micro-steps. The SmartFusion2 deterministic motor control GUI allows for the dynamic tuning of parameters such as reference speed, Kp/Ki gains of PI controllers and viewing internal signals for debugging. The kit also supports various communication interfaces including Ethernet, CAN, RS485, USB, and others. Motor performance is tested for speeds exceeding 30,000 RPM for sensorless field oriented control (FOC), with a low latency of 1.2μs when implementing FOC with sensors and 2μs when designing sensorless FOC at 100MHz, enabling switching frequencies up to 500kHz.

Furthermore, evaluation versions of the file system emFile, graphics library emWin, emUSB Host & Device, and TCP/IP stack embOS/IP (including web server demo) enable full use of the available emPower peripherals.emPower also features a J-Link OB, an on-board version of Segger’s debug probe J-Link, which includes drag & drop programming and COM-Port support. There are three expansion interfaces to easily connect additional modules. Each connector provides I2C, SPI, UART, GPIO/timer, analog input and power. A display adapter connector enables the connection of small TFT displays.The emPower board is based on a Freescale Kinetis K66 MCU with 256KB SRAM and 2MB flash memory. This MCU is built on the ARM Cortex-M4F core and is optimized for applications requiring large memory densities and low-power processing efficiency. Non-volatile storage capability of the board is provided by means of a 1Gbit SLC NAND Flash with a built-in ECC controller. Segger www.segger.com/empower.html MOST networks get link into Genivi The next Linux Mainline Kernel will contain a driver for the MOST infotainment data network technology. Thus, the MOST world can be integrated into the Linux-based infotainment operating system Genivi.According to MOST Technical Coordinator Wolfgang Bott, the Mainline Kernel will be equipped with a Linux starting with version 4.3. This piece of software enables access to all MOST data types. Likewise it supports the USB, MediaLB and I2C interfaces. The driver also supports standard Linux interfaces such as ALSA for audio and V4L2 for video data as well as IP data communications over the standard Linux Networking Stack.Market researcher IHS projects that by 2020, Linux will lead the estimated 130 million unit in-vehicle-infotainment (IVI) market with a 41.3 percent share, taking 53.7 million units. Linux adoption is growing because it provides automotive designers with an open-source platform that allows them to maximize the reuse of existing work, while making their own incremental improvements. Additionally, Automotive Grade Linux (AGL) was built on top of a well-tested and stable Linux stack that is already being used in embedded and mobile devices. MOST www.mostcooperation.com General-purpose power-quality monitor for on-site testing and troubleshooting The Yokogawa CW500 power quality monitor, a general-purpose unit for field and on-site testing and troubleshooting, is the latest addition to the company’s range of power measuring instruments.Featuring a range of clamp-on current probes, built-in data logging and measurements conforming to the IEC 6100-4-30 Class S standard, the CW500 is a multi-function instrument designed to aid the inspection and maintenance of power quality in factories, commercial or public facilities. In particular, it will detect, measure and record events such as voltage swells, sags, dips or interruptions, inrush currents, harmonics distortion and flicker which can have an adverse effect on equipment operation or energy efficiency.The 4-channel instrument can measure multiple power lines in configurations from single-phase/2-wire up to 3-phase/4-wire, and will simultaneously measure AC voltage input on three channels, current input on four channels and DC voltage input on two channels. Parameters measured include the instantaneous, average and maximum/minimum values of voltage, current, DC input voltage, power, power factor and phase angle, along with phase advanced capacitance calculation.All measurements are displayed on the built-in colour screen in list, waveform, or trend formats with direct keypad control.
