This technical brief demonstrates the operation of the MCP2150 with the Palm Operating System (OS). The MCP2150 is an IrDA protocol handler with an encoder/decoder. This allows the MCP2150 to be used as a Virtual Connector, a wireless link between an embedded application and an IrDA host. This host can be a handheld device using the Palm OS. Personal Digital Assistants (PDA) devices are an excellent host platform for use with the MCP2150 because of the light weight, low cost, ease of use, and portability of these devices.
