demonstrate the MCP2120 and MCP2150 devices, and the PC requirements.

Chapter 3: MCP2120 Tutorial – This chapter provides a detailed description

of the steps to get the MCP2120 Developer’s board operating. These steps

include the configuration of the Developer’s boards and the Terminal

Emulation program (Hyperterminal) used on the PC.

Chapter 4: MCP2150 Tutorial – This chapter provides a detailed description

of the steps to get the MCP2150 Developer’s board operating. These steps

include the configuration of the Developer’s boards, the Terminal Emulation

program (Hyperterminal) used on the PC, and the installation and

configuration of the PC IrDA standard drivers.

Chapter 5: Using PICDEM 1 or PICDEM 2 Board as Host. This chapter

discusses the use of the PICDEM boards as a demonstration platform as a

Host Controller for an MCP2120 Developer’s Board or an MCP2150

Developer’s Board. This chapter makes reference to Application Notes which

contain demonstration code.

Appendix A: Hardware Description: This appendix describes in detail the

hardware of the MCP2120 Developer’s board and MCP2150 Developer’s

board. This includes the component layout of each board (silkscreen) and the

schematic of each board.
