Cross-platform application development framework works on all leading platforms Digia has launched version Qt 5.2 of its cross-platform application and user interface (UI) development framework. By adding support for Android and iOS to its extensive range of desktop, mobile and embedded operating system platforms and enhancing its core performance and functionality, Qt 5.2 is claimed to be the only cross-platform development framework for UI and non-UI creation to enable intuitive platform-independent software applications no matter the target device or screen size. Under the Qt Enterprise offering, Qt 5.2 opens the door to increased mobility of enterprise applications, supporting enterprise-ready multiscreen applications that users can experience from desktop to smartphone to automobile to TV. In addition to Android and iOS support, Qt 5.2 also introduces Qt Cloud Services, developed to address the cloud computing needs of enterprises and developers, with data storage and user management. The Qt Cloud Services allow users to develop, test, deploy and manage applications with one Qt. Qt 5.2 also includes a new JavaScript engine and Scene Graph renderer that further improve the functionality and performance of Qt Quick QML. New modules for Positioning, Bluetooth and NFC have also been introduced, as well as a bundled-in Qt Creator 3.0, the Qt integrated development environment (IDE). The new application development framework supports 15 leading operating systems. Digia Qt http://qt.digia.com 25mm THIN Mini-ITX with Core processor targets space-limited embedded application Advantech has developed an industrial-grade THIN Mini-ITX motherboard, AIMB-230, supporting the latest dual core Intel Core i5-4300U and Intel Core Celeron 2980U processors with BGA1168 socket. The AIMB-230 is a low profile Mini-ITX design of only 25mm in height with a wide variety of I/O functions to fulfill an assortment of space-limited applications. AIMB-230 can be applied in the many embedded applications such as nursing carts, slim panel PC, slim signage box, vending machines, small POS systems and portable media devices. The AIMB-230 incorporates the22nm Intel Core i processor architecture, which supports a dual-core single-chip processor (MCP) with best-in-class energy saving within a 15W TDP. Only 25mm in height, AIMB-230 offers a variety of I / O connections. It also integrates a 3D GT3/GT2 graphics chipset which provides high-quality, high-resolution three-screen output (DP / HDMI, DP + +, LVDS / eDP), coupled with HD Audio codec support and supports up to 16GB of DDR3L 1600MHz low power memory. The AIMB-230 comes embedded with iManager, an intelligent self-management firmware agent, which gives applications smart self-control, resource management, and auto-protection features to enhance security and system reliability, and simplify integration and configuration. Advantech www.advantech.eu Qi compliant wireless power receiver IC reduces heat generation by 30 percent Toshiba Electronics Europe (TEE) has launched a wireless power receiver IC that complies with Qi Standard Low Power Specifications version1.1. The TC7761WBG will be used in wireless power supply applications, such as smartphones and mobile accessories. ICs used in mobile applications including smartphones, are required to generate heat at low level, to prevent overheating. The TC7761WBG is fabricated with a combined CMOS-DMOS wafer process that cuts heat generation to 70% that of an equivalent product while achieving 95% power conversion efficiency. The IC’s built-in protocol authentication circuit, includes a foreign object detection (FOD) function, eliminates the need for an external microcontroller and contributes to simplified system designs. TC7761WBG has been Qi certified for an output power of 3.5 W, and can handle a maximum output power of 5W. Shipments of mass produced chips are now available to buy. Toshiba www.toshiba-components.com Micronas takes ARM 32-bit core to brushless DC motor controls Sensor system manufacturer Micronas has licensed the Cortex- M3 32-bit RISC processor from ARM Ltd. for its next generation of brushless DC motor control solutions in a single IC. These ARM-based motor controllers will complement Micronas’ existing line of 8051-based devices and enable solutions that require more intelligence. The Cortex-M3 processor with its deterministic 3-stage pipeline provides an ideal blend of high performance and instruction efficiency the company’s experts find - in particular due to the use of the Thumb-2 instruction set, hardware divider, and single-cycle multiplier. The processor is also equipped with essential microcontroller features, such as low latency interrupt handling, integrated sleep modes, debug and trace capabilities, as well as best-in-class software development tool chain. The company’s embedded controllers for use in automotive and industrial applications are single chip, high-voltage controllers with flexible peripherals and direct motor driving capabilities. The various integrated digital and analog components include comparators, diagnosis and protection functions, programmable gain amplifier, A/D converter, communication interfaces, direct 12 V operation regulators, as well as power bridges. These features make the system lighter in weight and save important space within the application which enables a compact and cost-effective motor system design. These embedded controllers further support various commutation schemes and can either be operated in a sensor-less or sensored mode in conjunction with the company’s HAL 2xy and HAL 5xy switch or 2D rotational encoder families. Typical applications for smart actuator system solutions include DC motor drives, fans and pumps.
