44 * This library can be configured at compile time by the following options / macros:
45 * For more details see: https://github.com/Arduino-IRremote/Arduino-IRremote#compile-options--macros-for-this-library
46 *
47 * - RAW_BUFFER_LENGTH Buffer size of raw input buffer. Must be even! 100 is sufficient for *regular* protocols of up to 48 bits.
48 * - IR_SEND_PIN If specified (as constant), reduces program size and improves send timing for AVR.
49 * - USE_ACTIVE_LOW_OUTPUT_FOR_SEND_PIN Reverts the polarity at the send pin.
50 * - USE_OPEN_DRAIN_OUTPUT_FOR_SEND_PIN 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!
51 * - SEND_PWM_BY_TIMER Disable carrier PWM generation in software and use (restricted) hardware PWM.
52 * - USE_NO_SEND_PWM Use no carrier PWM, just simulate an **active low** receiver signal. Overrides SEND_PWM_BY_TIMER definition.
53 * - USE_ACTIVE_HIGH_OUTPUT_FOR_NO_SEND_PWM Simulate an **active high** receiver signal instead of an active low signal.
54 * - EXCLUDE_EXOTIC_PROTOCOLS If activated, BANG_OLUFSEN, BOSEWAVE, WHYNTER, FAST and LEGO_PF are excluded in decode() and in sending with IrSender.write().
55 * - EXCLUDE_UNIVERSAL_PROTOCOLS If activated, the universal decoder for pulse distance protocols and decodeHash (special decoder for all protocols) are excluded in decode().
56 * - DECODE_* Selection of individual protocols to be decoded. See below.
57 * - USE_THRESHOLD_DECODER May give slightly better results especially for jittering signals and protocols with short 1 pulses / pauses.
58 * - MARK_EXCESS_MICROS Value is subtracted from all marks and added to all spaces before decoding, to compensate for the signal forming of different IR receiver modules.
59 * - RECORD_GAP_MICROS Minimum gap between IR transmissions, to detect the end of a protocol.
60 * - FEEDBACK_LED_IS_ACTIVE_LOW Required on some boards (like my BluePill and my ESP8266 board), where the feedback LED is active low.
61 * - NO_LED_FEEDBACK_CODE This completely disables the LED feedback code for send and receive.
62 * - NO_LED_RECEIVE_FEEDBACK_CODE This disables the LED feedback code for receive.
63 * - NO_LED_SEND_FEEDBACK_CODE This disables the LED feedback code for send.
64 * - IR_INPUT_IS_ACTIVE_HIGH Enable it if you use a RF receiver, which has an active HIGH output signal.
65 * - IR_SEND_DUTY_CYCLE_PERCENT Duty cycle of IR send signal.
66 * - MICROS_PER_TICK Resolution of the raw input buffer data. Corresponds to 2 pulses of each 26.3 us at 38 kHz.
67 * - IR_USE_AVR_TIMER* Selection of timer to be used for generating IR receiving sample interval.
