productroundup 320W DC/DC regulated & isolated converters in compact outline Vicor has extended its range of DCM modules using its own VIA package format; three additional 48V input nominal modules (36-75V range), in a 3414 VIA package (3.38 x 1.40 x 0.37 in, or 86 x 35.5 x 9.4 mm), have output voltages of 12, 24, and 48V, with power levels of 320W, achieving a power density up to 183 W/in³. With regulation accuracy of ±0.5%, and with integral heatsinking in the VIA package, the devices are modular DC-DC converters operating from an unregulated, wide range input, to generate an isolated and regulated high efficiency output with higher power density. Smart home reference designs for connected-device developers Silicon Labs has created pre-certified occupancy sensor and smart outlet designs that employ its multiprotocol Wireless Gecko MCUs and ZigBee Mesh Stack. There are two wireless occupancy sensor and smart outlet reference designs for the home automation market to provide IoT connected devices. The FCC and UL-pre-certified reference designs include all of the hardware, firmware and software tools required to create connected home products based on Silicon Labs’ ZigBee “Golden Unit” Home Automation (HA 1.2) software stack and multiprotocol Wireless Gecko system-onchip (SoC) range. Complete article, here ARM-based starter kit presents complete design environment Distributor Rutronik (Ispringen, Germany) has ARM-based Starter Kits from Advantech; they are presented as allowing a user to begin the ARM development with only ten minutes of setup time; and that the kits include all key elements of a development environment. The kits host NXP and TI processors for ARM platform evaluation and development. They include key elements of a development environment including main boards with CPU cables, adapter cards, LCD panel and power adapter. A built-in OS image in Linux allows users to start their evaluation immediately. Complete article, here RTOS visualization tool looks deeper into running code Percepio AB (Västerås, Sweden), in its Percepio Tracealyzer 3.1 Release, offers improved tools that add support for trace streaming over USB, and provide detection of dynamic memory leaks, among a range of updates. The trace recorder library is now easier to configure for streaming over custom interfaces, and includes support for USB streaming on STM32 (easily adapted for other MCUs). USB offers excellent performance for RTOS tracing and over 600 kB/sec has been measured on an STM32 using USB 2, several times more than required. Other stream ports include TCP/IP (example for lwIP) and SEGGER J-Link debug probes. Tracealyzer 3.1 can also receive trace streams via Windows COM ports, e.g. from USB CDC connections, UART connections or any virtual COM port provided by other target interfaces. Tracealyzer v3.1 has also been extended to identify memory leaks in systems that use dynamic memory allocation.
