Advanced Communication Solutions for Lighting Contributed by Microchip Technology www.microchip.com Contents Viewpoint Wireless Communication Using IrDA® Wireless Design Choices Advanced Communication Solutions for Lighting Analog news S everal advanced wired and wireless communication interfaces are being evaluated for use in a multitude of innovative lighting applications. These interfaces include ZigBee™ and MiWi™ wireless protocols based on the IEEE 802.15.4 standard, Ethernet, USB, CAN and LIN. Zigbee™ protoCol The ZigBee protocol is an industry standard protocol for wireless networking. Specifically designed for low cost and relatively low bandwidth automation applications it allows the quick deployment of several networking flexible topologies, including star, cluster and mesh. The PIC18F family of microcontrollers offers the ideal combination of performance and low power features required to implement an efficient ZigBee solution. miwi™ protoCol Developed by Microchip, the MiWi protocol is a simple wireless protocol that is designed for low data rate, short distance, cost constrained networks. Based on the IEEE 802.15.4™ wireless personal area network (WPAN) specification, the MiWi protocol is a small footprint alternative to ZigBee and is ideal for cost-sensitive application nodes with limited memory. No certification is required to use MiWi, and the protocol stack is provided under a free license when using Microchip’s microcontrollers and the MRF24J40 transceiver. ethernet interfaCe Ethernet (10baseT) connectivity is becoming ubiquitous and most new office and industrial buildings are being wired for Ethernet. As lower cost solutions are becoming available it is increasingly tempting to use Ethernet for even the simplest control and diagnostic applications. In particular, Microchip Technology makes available three solutions that greatly simplify the design of any Ethernet interface. The ENC28J60 Ethernet interface controllers incorporate MAC and PHY interfaces, connecting with any PIC microcontroller via a simple SPI interface. Next, the PIC18F97J60 family of high performance 8-bit microcontrollers offers from Microchip analog page Interface products overview Sample center microchipDIRECT Reference designs/ app notes Technical training 11 · ProjeCt ANALog · mAr 08 http://www.microchip.com http://www.microchip.com http://www.microchip.com/analog http://www.microchip.com/analog http://www.microchip.com/interface http://www.microchip.com/interface http://sample.microchip.com/Default.aspx?testCookies=true http://www.microchipdirect.com/catalogselection.aspx?returnURL=default.aspx http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1469&filter1=function&redirects=appnotes http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1469&filter1=function&redirects=appnotes http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1423
