MARK_EXCESS

#define MARK_EXCESS   MARK_EXCESS_MICROS

Definition at line 320 of file IRremote.hpp.

MARK_EXCESS_MICROS

#define MARK_EXCESS_MICROS   20

MARK_EXCESS_MICROS is subtracted from all marks and added to all spaces before decoding, to compensate for the signal forming of different IR receiver modules For Vishay TSOP*, marks tend to be too long and spaces tend to be too short.

If you set MARK_EXCESS_MICROS to approx. 50us then the TSOP4838 works best. At 100us it also worked, but not as well. Set MARK_EXCESS to 100us and the VS1838 doesn't work at all.

The right value is critical for IR codes using short pulses like Denon / Sharp / Lego

Observed values: Delta of each signal type is around 50 up to 100 and at low signals up to 200. TSOP is better, especially at low IR signal level. VS1838 Mark Excess -50 at low intensity to +50 us at high intensity TSOP31238 Mark Excess 0 to +50

#define MILLIS_IN_ONE_SECOND   1000L

Definition at line 254 of file IRremote.hpp.

PULSE_CORRECTION_NANOS

#define PULSE_CORRECTION_NANOS   600

Define to disable carrier PWM generation in software and use (restricted) hardware PWM.

Define to use no carrier PWM, just simulate an active low receiver signal. Define to use or simulate open drain output mode at send pin. Attention, active state of open drain is LOW, so connect the send LED between positive supply and send pin! This amount is subtracted from the on-time of the pulses generated for software PWM generation. It should be the time used for digitalWrite(sendPin, LOW) and the call to delayMicros() Measured value for Nano @16MHz is around 3000, for Bluepill @72MHz is around 700, for Zero 3600

Definition at line 236 of file IRremote.hpp.

RAWBUF

#define RAWBUF   101

Macros for legacy compatibility.

Definition at line 317 of file IRremote.hpp.

RECORD_GAP_MICROS

#define RECORD_GAP_MICROS   8000

Minimum gap between IR transmissions, to detect the end of a protocol.

Must be greater than any space of a protocol e.g. the NEC header space of 4500 us. Must be smaller than any gap between a command and a repeat; e.g. the retransmission gap for Sony is around 15 ms for Sony20 protocol. Keep in mind, that this is the delay between the end of the received command and the start of decoding.

Definition at line 163 of file IRremote.hpp.

RECORD_GAP_MICROS_WARNING_THRESHOLD

#define RECORD_GAP_MICROS_WARNING_THRESHOLD   15000
