Time aware shaper protocols shape in-vehicle networks

Tue, Feb 12, 2019

Excelfore adds time aware shaper (TAS) protocols for time sensitive networking (TSN) for automotive use.

To meet automotive requirements for deterministic network behaviour, new protocols must be added to Ethernet stacks to provide audio/video bridging (AVB) and TSN to enable Ethernet to meet the demands of in-vehicle infotainment, control and safety systems.

The Excelfore TAS protocols reside in network talkers and bridges with support for TSN enhancements including IEEE 802.1Qbv and 802.1Qci, explains Excelforce. The TAS provides a circuit-switched/ time-division-multiplexed (TDM) channel into the packet-based Ethernet network. This enables a specific time window to be guaranteed for the delivery of high priority traffic, for example for automotive control systems.

The Excelfore TAS has demonstrated the ability to reduce the variance in measured propagation delays by more than 65 per cent,% compared to Ethernet traffic without the TAS, reports Excelforce. This ensures deterministic sub-100 microsecond accuracy for time-sensitive traffic.

The Excelfore eAVB/TSN protocol stack, including the TAS protocol, is available for Linux, QNX, Integrity and Android operating systems, as well as a variety of smaller real time operating systems (RTOS). It is for use in cameras, video displays, head units, ECUs, and network gateways that bridge to CAN, LIN, and other popular automotive buses.

The TAS protocol will be demonstrated at this week’s Automotive Ethernet Congress (13 to 14 February) in Munich, Germany.

Excelfore provides cloud platform and connectivity applications for intelligent transportation. It provides middleware solutions for smart mobility networks that enable OEMs and suppliers to build the next generation of smart, autonomous and learning vehicles, fleets and associated infrastructure. In addition to the eAVB/TSN protocol stack, it provides the cloud-to-vehicle eSync system for over the air updates, diagnostics and telematics.

Low-cost RFID ICs bring flexible electronics to everyday objects

Fri, Feb 08, 2019

Cost-effective digital traceability and interactivity can be introduced to everyday objects with the ConnectIC family of flexible RFID circuits, says PragmatIC.

The flexible IC company introduces the first products in the ConnectIC family, the PR1101 and PR1102 flexible integrated circuits (FlexICs). They are designed for use in closed high frequency, radio frequency identification (HF RFID) systems. The company expects the ConnectIC family to accelerate the smart packaging market.

They FlexICs have been developed using PragmatIC’s patented technologies and the ConnectICs are claimed to deliver connectivity at the lowest cost point in the market. These FlexICs are thin and flexible, making them suitable for embedding into a range of substrates, including paper and plastic. They reduce the complexity of inlays by using single layer antennae, which further reduces the cost to brand owners and retailers.

The ConnectICs can be used for high volume, fast moving consumer goods (FMCGs) and other mass market applications; PragmatIC believes they mean that electronic connectivity no longer limited to high value, luxury items.

The PR1100 is designed for proximity identification, with rapid detection of objects when one or more low-cost custom readers are integrated into the system. They can be used for hierarchical inventory management, item identification and tracking, supply chain assurance and brand authentication. They are targeted at market segments such as food and beverage, personal and home care, pharmaceutical and healthcare. They also support the introduction of digital interactivity into physical toys and games.

Win a Microchip MPLAB PICkit 4 In-Cirucit Debugger

Fri, Feb 01, 2019

Win a Microchip MPLAB PICkit™ 4 In-Circuit Debugger (PG164140) from Softei.com

The Microchip MPLAB PICkit 4 In-Circuit Debugger allows fast and easy debugging and programming of PIC® and dsPIC® flash microcontrollers, using the powerful graphical user interface of MPLAB X Integrated Development Environment (IDE).

The MPLAB PICkit 4 programs faster than its predecessor with a powerful 32-bit 300MHz SAME70 MCU and comes ready to support PIC and dsPIC MCU devices. Along with a wider target voltage, the PICkit 4 supports advanced interfaces such as 4-wire JTAG and Serial Wire Debug with streaming Data Gateway, while being backward compatible for demo boards, headers and target systems using 2-wire JTAG and ICSP.

Key features of the PICkit 4 include matching silicon clocking speed, supplying up to 50Ma of power to the target, a minimal current consumption at <100µA from target, and an option to be self-powered from the target.

 The MPLAB PICkit 4 is connected to the design engineer’s computer using a high-speed 2.0 USB interface and can be connected to the target via an 8-pin Single In-Line (SIL) connector. The connector uses two device I/O pins and the reset line to implement in-circuit debugging and In-Circuit Serial Programming™ (ICSP™).

Currently, the MPLAB PICkit 4 In-Circuit Debugger/Programmer supports many but not all PIC MCUs and dsPIC DSCs, but is being continually upgraded to add support for new devices.

For your chance to win a Microchip MPLAB PICkit 4 In-Circuit Debugger, visit http://page.microchip.com/Softei-PICkit-4.html and enter your details in the online entry form.
