pulse Software test libraries for STM32 Microcontrollers boost functional safety Yogitech (Pisa, Italy), provider of functional safety solutions, has announced that its fRSTL libraries for STM32 microcontrollers from STMicroelectronics have been positively assessed by TÜV Rheinland for, among other attributes, functional safety certification. Heinz Gall, Global Business Field Manager, Functional Safety of TÜV Rheinland, said, “Yogitech’s fRSTL libraries have been positively assessed according to the IEC61508:2010 functional safety standard for the systematic capability (SC3) and the Diagnostic Coverage, making them suitable to be integrated into SIL2, HFT=0 and SIL3 HFT=1 applications. The final report and certificate will be issued by first week of December 2014”. fRSTL for ST’s STM32 MCUs is a set of software libraries addressing the STM32 microcontroller series, and intended to detect hardware random faults. They are an application-independent, off-the-shelf product designed to be easily integrated into safety-relevant systems. fRSTL libraries build on fRMethodology, Yogitech’s techniques that apply functional safety to integrated circuits using a white-box approach, and are duly verified by means of intensive fault injection simulations on the RTL and netlist level, to which Yogitech has access. CSR’s accurate indoor location available to Android device developers A software library brings, says the provider of SiRF location products, plug and play simplicity to Android app developers: the SiRFusion Software Development Kit (SDK) enables indoor positioning for Android developers looking to create next-generation apps. Developers can now use the SiRFusion library to rapidly integrate new locationbased capabilities and services such as indoor location tagging and analytics for social networking applications, indoor navigation, lone worker efficiency and safety capabilities, as well as indoor asset tracking and targeted e-commerce services. Mobile applications with integrated SiRFusion can – CSR says Complete article, here – deliver the ubiquity of outdoor navigation to indoor environments without costly surveys or infrastructure upgrades. SiRFusion combines real-time Wi-Fi signals, satellite positioning information, pedestrian dead reckoning, and the company’s cloud-based CSR Positioning Center to calculate accurate indoor location. SiRFusion automatically crowd-sources a venue’s indoor Wi-Fi signatures as consumers walk through the location, and it has also been architected to accommodate future proximity and location technologies such as Bluetooth Smart beacons, Wi-Fi Round Trip Time (RTT), and Indoor Messaging System (IMES). USB-scope drivers for PicoScopes now run on BeagleBone and Raspberry Pi boards Pico Technology has released beta drivers for its oscilloscope and data logging devices to run on the ARM-based BeagleBone Black and Raspberry Pi development boards. The drivers give programmers access to a wide range of compact, economical USB oscilloscopes and data loggers. These include highspeed oscilloscopes with bandwidths up to 500 MHz, high-resolution 12-bit and 16-bit oscilloscopes, and deepmemory oscilloscopes with buffer sizes up to 512 Msamples. Most Pico- Scope oscilloscopes also offer advanced digital triggering, fast Complete article, here block-mode and streaming-mode data capture, and a built-in signal generator or arbitrary waveform generator. The data logger range includes multichannel voltage loggers, 8-channel thermocouple loggers and the educational DrDAQ multifunction logger. Separate driver packages and snippets of C code are available for Raspbian and Debian systems. Similar code could be developed in C-compatible programming languages such as C++, Java and JavaScript.
