IRDA 1.0 标准协议源代码

***** IrMEM Application *****

This simple application allows you receive a message
via IrOBEX and store it into the EEPROM.
Later on, the same message can be sent back via IrOBEX.

***** IrMEM Pin Configuration *****

XTAL1, XTAL2       - Crystal Oscillator 3.6864 MHz

PD0(RxD), PD1(TxD) - Connected to a IrDA signal encoder/decoder
                     e.g. MCP2120, MAX3100

PD2                - Input (e.g. Button)
                     If pulled low (GND),
                     the device will beam the EEPROM content
PD6                - Output (e.g. LED)
                     While the device beams the EEPROM content,
                     this line goes low (GND)

PD3                - Input (e.g. Button)
                     If pulled low (GND),
                     the device will wait for up to 30 seconds for
                     an incoming IrOBEX message that is stored into 
                     the EEPROM
PD7                - Output (e.g. LED)
                     While the device waits for a message to be stored,
                     this line goes low (GND)

***** IrMEM Comments *****

The maximum message size stored in the EEPROM is 508 bytes including
the pathname of the message itself

The IrMEM application powers down the Atmel AVR MCU
after initialization and waits for either PD2 or PD3
to go to level low (GND).

Please make sure that the IrDA signal encoder/decoder and the
IrDA optical transceiver also goes to power saving mode
if the device is battery operated.
