Wireless Communication Using the IrDA® Standard Protocol Contributed by Microchip Technology www.microchip.com mcP2510/2515 can dEvEloPEr’s Kit Contents Viewpoint Wireless Communication Using IrDA® Wireless Design Choices Advanced Communication Solutions for Lighting Analog news T he two most popular mediums in the wireless arena are Infrared (IR) and Radio Frequency (RF). When asked to develop a wireless system, you may be concerned about cost, ease-of-design and distance requirements. IR technologies are better suited for short distance, low-to-medium data throughput, wireless communication channels. Two common types of IR technologies are currently in use. These are the TV Remote (TVR) and the IrDA (Infrared Data Association) standard protocol. The lowest cost wireless connection technology is TVR. The trade-off with this technology is between distance and bit-rate. Usually this interface is also unidirectional. If a bidirectional, 5 · ProjeCt ANALog · mAr 08 Part Number: DV251001 Devices Supported: MCP2510, MCP2515 This developer’s kit offers a unique combination of a software development tool and a CAN message/ communication tool. This kit helps speed up software development and enable introduction of CAN to those who are unfamiliar with the protocol. The MCP2510 and MCP2515 are 18-pin stand-alone CAN (Control Area Network) controllers, featuring industry standard SPI serial interface, interrupt capability, message masking and filtering, message prioritization, multi-purpose I/O pins, and multiple transmit/receive buffers.

This infrared communication standard has been defined by the IrDA industrybased group (see the IrDA System Protocol consortium web site at www.irda.org). This group has developed communication standards that are well suited for low-cost, short-range, point-to-point infrared channels. These types of channels operate over a wide range of speeds under a cross-platform environment. IrDA standards have been used to install over 300 million low-cost, shortrange communication systems in laptops, printers, handheld PCs, and PDAs, to name a few.
