Trying to shortcut IrDA development I purchased the Microchip MCP2120/MCP2150 development board. Well dealing with the "wrong" (as far as this site is concerned) company, the manual, of course, was blank for the chapter about the MCP2150 which, supposedly handles stack etc.
Does anyone know what this chip does and how to set the dev board up?
