The key signals for the MCP215X-to-IR transceiver circuit are shown in
TABLE 2-12:
TXIR
RXIR
Legend: A = Analog
In addition to the signals described in
input is connected to the RESET output of the Host Controller (PIC16F877A I/O pin
RC0), which asserts low after the RESET push button switch is asserted and the OSC1
and OSC2 pins are connected to an external 11.0592 MHz oscillator; specified in the
MCP2150 Data Sheet (DS21655) and the MCP2155 Data Sheet (DS21690)
2.8.2.1
The MCP215X (U3) implements 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. The MCP215X allows the replacement of the serial cable with a wire-
less interface. The MCP215X implements the entire protocol layer, while the Host
Controller (PIC16F877A) talks to the MCP215X 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 C. “Board Testing” shows the connection sequence between a Primary
device and the MCP215X (Secondary device). This connection sequence is shown at
an overview level and does not show exact operation.
