Match & decode a generic/typical IR message. The data is stored in result_bits_ptr or result_bytes_ptr depending on flag `use_bits`.

Note
  Values of 0 for hdrmark, hdrspace, footermark, or footerspace mean skip that requirement.

Parameters

  [in] | data_ptr | A pointer to where we are at in the capture buffer.
  [out] | result_bits_ptr | A pointer to where to start storing the bits we decoded.
  [out] | result_bytes_ptr | A pointer to where to start storing the bytes we decoded.

  [in] | atleast | Is the match on the footerspace a matchAtLeast or matchSpace?
  [in] | tolerance | Percentage error margin to allow. (Default: kUseDefTol)
  [in] | excess | Nr. of uSeconds. (Def: kMarkExcess)
  [in] | MSBfirst | Bit order to save the data in. (Def: true) true is Most Significant Bit First Order, false is Least Significant First

Returns
  If successful, how many buffer entries were used. Otherwise 0.

## ◆ _validTolerance()

uint8_t IRrecv::_validTolerance | ( | const uint8_t | percentage | ) |
| private

Convert the tolerance percentage into something valid.

Parameters

  [in] | percentage | An integer percentage.

## ◆ compare()

uint16_t IRrecv::compare | ( | const uint16_t | oldval,
|  | const uint16_t | newval
| ) |  |
| private

Compare two tick values.

Parameters

  [in] | oldval | Nr. of ticks.
  [in] | newval | Nr. of ticks.

Returns
  0 if newval is shorter, 1 if it is equal, & 2 if it is longer.

Note
  Use a tolerance of 20%

## ◆ copyIrParams()

void IRrecv::copyIrParams | ( | volatile irparams_t * | src,
|  | irparams_t * | dst
| ) |  |
| private

Make a copy of the interrupt state & buffer data. Needed because irparams is marked as volatile, thus memcpy() isn't allowed. Only call this when you know the interrupt handlers won't modify anything. i.e. In kStopState.

Parameters

  [in] | src | Pointer to an irparams_t structure to copy from.
  [out] | dst | Pointer to an irparams_t structure to copy to.

## ◆ crudeNoiseFilter()

void IRrecv::crudeNoiseFilter | ( | decode_results * | results,
|  | const uint16_t | floor = `0`
| ) |  |
| private

Remove or merge pulses in the capture buffer that are too short.

Parameters

  [in,out] | results | Ptr to the decode_results we are going to filter.
  [in] | floor | Only allow values in the buffer large than this. (in microSeconds)

## ◆ decode()

bool IRrecv::decode | ( | decode_results * | results,
|  | irparams_t * | save = `NULL`,
|  | uint8_t | max_skip = `0`,
|  | uint16_t | noise_floor = `0`
| ) |  |

Decodes the received IR message. If the interrupt state is saved, we will immediately resume waiting for the next IR message to avoid missing messages.

Note
  There is a trade-off here. Saving the state means less time lost until we can receiving the next message vs. using more RAM. Choose appropriately.

Parameters

  [out] | results | A PTR to where the decoded IR message will be stored.
  [out] | save | A PTR to an irparams_t instance in which to save the interrupt's memory/state. NULL means don't save it.
  [in] | max_skip | Maximum Nr. of pulses at the begining of a capture we can skip when attempting to find a protocol we can successfully decode. This parameter can dramatically improve detection of protocols when there is light IR interference just before an incoming IR message, however, it comes at a steep performace price. (Default is 0. No skipping.)

Warning
  Increasing the `max_skip` value will dramatically (linearly) increase the cpu time & usage to decode protocols. e.g. 0 -> 1 will be a 2x increase in cpu usage/time. 0 -> 2 will be a 3x increase etc. If you are going to do this, consider disabling protocol decoding for protocols you are not expecting.

Parameters

  [in] | noise_floor | Pulses below this size (in usecs) will be removed or merged prior to any decoding. This is to try to remove noise/poor readings & slightly increase the chances of a successful decode but at the cost of data fidelity & integrity. (Defaults to 0 usecs. i.e. Don't filter; which is safe!)

Warning
  DANGER: Here Be Dragons! If you set the `noise_floor` value too high, it WILL break decoding of some protocols. You have been warned! Any non-zero value has the potential to cook the captured raw data i.e. The raw data is going to lie to you. It may obscure hardware, circuit, & environment issues thus making it impossible to support you accurately or confidently. Values of <= 50 usecs will probably be safe. 51 - 100 usecs might be okay. 100 - 150 usecs is "Danger, Will Robinson!". 150 - 200 usecs expect broken protocols. At 200+ usecs, you have protocols you can't decode!!

Returns
  A boolean indicating if an IR message is ready or not.

## ◆ decodeAirton()

bool IRrecv::decodeAirton | ( | decode_results * | results,

## ◆ decodeAiwaRCT501()

bool IRrecv::decodeAiwaRCT501 | ( | decode_results * | results,
|  | uint16_t | offset = `kStartOffset`,
|  | const uint16_t | nbits = `kAiwaRcT501Bits`,
|  | const bool | strict = `true`
| ) |  |
| private

Decode the supplied Aiwa RC T501 message. Status: BETA / Should work.

Parameters

  [in,out] | results | Ptr to the data to decode & where to store the decode result.
  [in] | offset | The starting index to use when attempting to decode the raw data. Typically/Defaults to kStartOffset.
  [in] | nbits | The number of data bits to expect.

Note
  Aiwa RC T501 appears to be a 42 bit variant of the NEC1 protocol. However, we historically (original Arduino IRremote project) treats it as a 15 bit (data) protocol. So, we expect nbits to typically be 15, and we will remove the prefix and postfix from the raw data, and use that as the result.

## ◆ decodeHash()

bool IRrecv::decodeHash | ( | decode_results * | results | ) |
| private

Decode any arbitrary IR message into a 32-bit code value. 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 signals, and see if each one is shorter (0), the same length (1), or longer (2) than the previous. Do the same with the SPACE signals. 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.

Note
  This isn't a "real" decoding, just an arbitrary value. Hopefully this code is unique for each button.

There are some other timing differences too, but the tolerances will overlap.

  `data_ptr` is assumed to be pointing to a "Mark", not a "Space".

Parameters

  [out] | result_ptr | A ptr to where to start storing the bits we decoded.
  [in] | remaining | The size of the capture buffer remaining.
  [in] | nbits | Nr. of data bits we expect.
  [in] | half_period | Nr. of uSeconds for half the clock's period. i.e. 1/2 wavelength
  [in] | tolerance | Percentage error margin to allow. (Default: kUseDefTol)
  [in] | starting_balance | Amount of uSeconds to assume exists prior to the current value pointed too.
  [in] | excess | Nr. of uSeconds. (Def: kMarkExcess)
  [in] | MSBfirst | Bit order to save the data in. (Def: true) true is Most Significant Bit First Order, false is Least Significant First
  [in] | GEThomas | Use G.E. Thomas (true) or IEEE 802.3 (false) convention?

Returns
  If successful, how many buffer entries were used. Otherwise 0.

Todo:
  Clean up and optimise this. It is just "get it working code" atm.

## ◆ matchMark()

bool IRrecv::matchMark | ( | const uint32_t | measured,
|  | const uint32_t | desired,
|  | const uint8_t | tolerance = `kUseDefTol`,
|  | const int16_t | excess = `kMarkExcess`
| ) |  |

Check if we match a mark signal(measured) with the desired within +/-tolerance percent, after an expected is excess is added.

Parameters

  [in] | measured | The recorded period of the signal pulse.
  [in] | desired | The expected period (in usecs) we are matching against.
  [in] | tolerance | A percentage expressed as an integer. e.g. 10 is 10%.
  [in] | excess | A non-scaling amount to reduce usecs by.

Returns
  A Boolean. true if it matches, false if it doesn't.

## ◆ matchMarkRange()

bool IRrecv::matchMarkRange | ( | const uint32_t | measured,
|  | const uint32_t | desired,
|  | const uint16_t | range = `100`,
|  | const int16_t | excess = `kMarkExcess`
| ) |  |

Check if we match a mark signal(measured) with the desired within a range (in uSeconds) either side of the desired, after an expected is excess is added.

Parameters

  [in] | measured | The recorded period of the signal pulse.
  [in] | desired | The expected period (in usecs) we are matching against.
  [in] | range | The range limit from desired to accept in uSeconds.
  [in] | excess | A non-scaling amount to reduce usecs by.

Returns
  A Boolean. true if it matches, false if it doesn't.

## ◆ matchSpace()

bool IRrecv::matchSpace | ( | const uint32_t | measured,
|  | const uint32_t | desired,
|  | const uint8_t | tolerance = `kUseDefTol`,
|  | const int16_t | excess = `kMarkExcess`
| ) |  |

Check if we match a space signal(measured) with the desired within +/-tolerance percent, after an expected is excess is removed.

Parameters

  [in] | measured | The recorded period of the signal pulse.
  [in] | desired | The expected period (in usecs) we are matching against.
  [in] | tolerance | A percentage expressed as an integer. e.g. 10 is 10%.
  [in] | excess | A non-scaling amount to reduce usecs by.

Returns
  A Boolean. true if it matches, false if it doesn't.

## ◆ matchSpaceRange()

|  | const uint32_t | desired,
|  | const uint16_t | range = `100`,
|  | const int16_t | excess = `kMarkExcess`
| ) |  |

Check if we match a space signal(measured) with the desired within a range (in uSeconds) either side of the desired, after an expected is excess is removed.

Parameters

  [in] | measured | The recorded period of the signal pulse.
  [in] | desired | The expected period (in usecs) we are matching against.
  [in] | range | The range limit from desired to accept in uSeconds.
