Definition at line 1634 of file IRReceive.hpp.

◆ decode()

bool IRrecv::decode ( )

The main decode function, attempts to decode the recently receive IR signal.

The set of decoders used is determined by active definitions of the DECODE_<PROTOCOL> macros. Results of decoding are stored in IrReceiver.decodedIRData.* like e.g. IrReceiver.decodedIRData.command.

Returns: false if no IR receiver data available, true if data available.

Definition at line 525 of file IRReceive.hpp.

◆ decode_old()

bool IRrecv::decode_old ( decode_results * aResults )

Definition at line 1713 of file IRReceive.hpp.

◆ decodeHash()

bool IRrecv::decodeHash ( )

decodeHash - decode an arbitrary IR code.

Instead of decoding using a standard encoding scheme (e.g. Sony, NEC, RC5), the code is hashed to a 32-bit value.

The algorithm: look at the sequence of MARK and SPACE signals, and see if each one is shorter (0), the same length (1), or longer (2) than the previous MARK or SPACE. Hash the resulting sequence of 0's, 1's, and 2's to a 32-bit value. This will give a unique value for each different code (probably), for most code systems.

Use FNV hash algorithm: http://isthe.com/chongo/tech/comp/fnv/#FNV-param Converts the raw code values into a 32-bit hash code. Hopefully this code is unique for each button. This isn't a "real" decoding, just an arbitrary value.

Returns: true if decoding was successful

Definition at line 845 of file IRReceive.hpp.

◆ decodePulseDistanceWidthData() [2/2]

bool IRrecv::decodePulseDistanceWidthData	(	uint_fast8_t	aNumberOfBits,
		uint_fast8_t	aStartOffset,
		uint16_t	aOneMarkMicros,
		uint16_t	aZeroMarkMicros,
		uint16_t	aOneSpaceMicros,
		uint16_t	aZeroSpaceMicros,
		bool	aMSBfirst
	)

Decode pulse distance width protocols.

We can have the following protocol timings Pulse distance: Pulses/marks are constant, pause/spaces have different length, like NEC. Pulse width: Pulses/marks have different length, pause/spaces are constant, like Sony. Pulse distance width: Pulses/marks and pause/spaces have different length, often the bit length is constant, like MagiQuest. Pulse distance width can be decoded like pulse width decoder, if this decoder does not check the length of pause/spaces.

Input is IrReceiver.decodedIRData.rawDataPtr->rawbuf[] Output is IrReceiver.decodedIRData.decodedRawData

Assume pulse distance if aOneMarkMicros == aZeroMarkMicros

Parameters

aNumberOfBits	Number of bits to decode from decodedIRData.rawDataPtr->rawbuf[] array.
aStartOffset	Offset in decodedIRData.rawDataPtr->rawbuf[] to start decoding. Must point to a mark.
aOneMarkMicros	Taken as constant BitMarkMicros for pulse distance.
aZeroMarkMicros	Not required if DECODE_STRICT_CHECKS is not defined.
aOneSpaceMicros	Taken as (constant) BitSpaceMicros for pulse width.
aZeroSpaceMicros	Not required if DECODE_STRICT_CHECKS is not defined.
aMSBfirst	If true send Most Significant Bit first, else send Least Significant Bit (lowest bit) first.

◆ getBiphaselevel()

uint_fast8_t IRrecv::getBiphaselevel ( )

Gets the level of one time interval (aBiphaseTimeUnit) at a time from the raw buffer.

The RC5/6 decoding is easier if the data is broken into time intervals. E.g. if the buffer has mark for 2 time intervals and space for 1, successive calls to getBiphaselevel will return 1, 1, 0.
