IRremote library API

The API uses an IRsend object to send a code, and an IRrecv object to receive a code. The library cannot send and receive at the same time, but can switch between sending and receiving.

Sending

IRsend irsend();

Creates a send object

irsend.sendNEC(data, bits)

Sends the value as an NEC-format IR code. bits specifies the length of the code, typically 16.

irsend.sendSony(data, bits)

Sends the value as a Sony-format IR code.

irsend.sendRC5(data, bits)

Sends the value as a RC5-format IR code.

irsend.sendRC6(data, bits)

Sends the value as a RC6-format IR code.

irsend.sendRaw(buf, len, hertz)

Sends a code corresponding to the buffer of raw durations.

Receiving

IRrecv irrecv(pin);

Creates a receiver object.

irrecv.enableIRIn();

Starts listening for an IR code.

int irrecv.decode(&results)

Returns 1 if there is a received code available, and 0 otherwise.
The fields of results are:
decode_type: NEC, SONY, RC5, RC6, or UNKNOWN
value: the received code value
bits: The number of bits received
rawbuf[]: Raw durations
rawlen: Number of records in rawbuf

irrecv.resume()

This must be called after irrecv.decode() to resume listening for a code.
