Oslo, Norway Radiocrafts AS has expanded its product line with a compact Zigbee-ready module with embedded Serial Port Profile and I/O mapping (SPPIO) software. The RC2200AT-SPPIO is a complete off-the-shelf Zigbee-ready module with a fully embedded application profile and mesh networking protocol stack supporting Full Function Device (FFD) and Reduced Function Device (RFD) operation. The tiny module is only 16.5 x 35.6 x 3.5 mm including the integrated antenna. The module acts like a serial port modem, and in addition it offers up to 16 digital and analogue I/Os that can be mapped to any other module within the mesh network. All configuration of the module is done through an easy-to-use AT-command interface using the serial port. In a practical network one module is configured as the PAN Coordinator, whereas the others are Routers or End Devices. The Routers will take part in the mesh network routing, whereas the End Devices can exploit the built-in power save features for battery applications. Once the modules are deployed they automatically organize in a multi-hop mesh network. Radiocrafts AS , Oslo, Norway. www.radiocrafts.com.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
