/*
 * ir_DistanceWidthProtocol.hpp
 *
 * Contains only the decoder functions for universal pulse width or pulse distance protocols!
 * The send functions are used by almost all protocols and are therefore located in IRSend.hpp.
 *
 * If RAM is not more than 2k, the decoder only accepts mark or space durations up to 50 * 50 (MICROS_PER_TICK) = 2500 microseconds
 * to save RAM space, otherwise it accepts durations up to 10 ms.
 *
 * This decoder tries to decode the protocols:
 * - Pulse distance with constant pulse length
 * - Pulse distance width with constant period length
 * - Pulse width with constant pause length - not enabled yet
 *
 * 1. Analyze all space and mark length
 * 2. Decide which protocol we have
 * 3. Try to decode with the mark and space data found in step 1
 * 4. Assume one start bit / header and one stop bit, since pulse distance data must have a stop bit!
 * No data and address decoding, only raw data as result.
 *
 * Pulse distance data can be sent with the generic function as in SendDemo example line 155:
 * https://github.com/Arduino-IRremote/Arduino-IRremote/blob/d51b540cb2ddf1424888d2d9e6b62fe1ef46859d/examples/SendDemo/SendDemo.ino#L155
 * void sendPulseDistanceWidthData(unsigned int aOneMarkMicros, unsigned int aOneSpaceMicros, unsigned int aZeroMarkMicros,
 *            unsigned int aZeroSpaceMicros, uint32_t aData, uint8_t aNumberOfBits, bool aMSBfirst, bool aSendStopBit = false)
 * The header must be sent manually with:
 *          IrSender.mark(MarkMicros)
 *          IrSender.space(SpaceMicros);
 *
 * Or send it by filling a DecodedRawDataArray and with the sendPulseDistanceWidthFromArray() function as in SendDemo example line 175:
 * https://github.com/Arduino-IRremote/Arduino-IRremote/blob/d51b540cb2ddf1424888d2d9e6b62fe1ef46859d/examples/SendDemo/SendDemo.ino#L175
 * sendPulseDistanceWidthFromArray(uint_fast8_t aFrequencyKHz, unsigned int aHeaderMarkMicros,
 *         unsigned int aHeaderSpaceMicros, unsigned int aOneMarkMicros, unsigned int aOneSpaceMicros, unsigned int aZeroMarkMicros,
 *         unsigned int aZeroSpaceMicros, uint32_t *aDecodedRawDataArray, unsigned int aNumberOfBits, uint8_t aFlags,
 *         unsigned int aRepeatPeriodMillis, int_fast8_t aNumberOfRepeats)
