MCP215X/40 DEVELOPER’S DAUGHTER BOARD DESCRIPTION
The following sections describe each element of this daughter board in further detail.
2.5.1
The MCP215X/40 Developer’s Daughter Board is powered by a 5V supply. This
voltage supply may be sourced via the PCB headers.
When the device is used in conjunction with the appropriate PICDEM Demo Board, the
power is supplied via the connector interface. If the MCP215X/40 Developer’s
Daughter Board is jumpered into an application circuit via the HD1 and HD2
connectors, the device power supply must be brought over as well.
2.5.2
This demo board highlights the MCP2150, MCP2155 or MCP2140 IrDA Protocol Stack
Controller device (U1) to demonstrate the implementation of an IR interface in an
embedded system application. The MCP2150, MCP2155 and MCP2140 devices
handle all IrDA standard protocol tasks (including the encoding/decoding of the
UART/IR bit stream), while allowing the system designer to easily interface the device
to a microcontroller via a standard UART port.
The IrDA standard protocol that the MCP215X and MCP2140 implement is the 9-wire
“cooked” service class in the IrCOMM application layer protocol of the IrDA standard
specification.
IrCOMM is the IrDA standard specification for the replacement of the communication
ports (serial and parallel) of a PC. This allows the replacement of the serial cable with
a wireless interface. The MCP215X and MCP2140 implements the entire protocol layer
and the encoding/decoding of the UART/IR bit stream, while the Host Controller talks
to the MCP215X or MCP2140 device as if it were a serial port with flow control.
The MCP215X operates as a Secondary device only, so it will not initiate IrDA standard
communication with other IrDA standard devices (neither a Secondary or Primary
device).
Appendix G. “MCP215X/40 Connection Sequence Overview” shows the connec-
tion sequence between a Primary device and the Secondary device. This connection
sequence is shown at an overview level and does not show exact operation.
