## Send pin
|
||||
Any pin can be choosen as send pin, because the PWM signal is generated by default with software bit banging, since `SEND_PWM_BY_TIMER` is not active.
|
||||
If `IR_SEND_PIN` is specified (as constant), it reduces program size and improves send timing for AVR. If you want to use a variable to specify send pin e.g. with `setSendPin(uint8_t aSendPinNumber)`, you must disable this macro. Then you can change send pin at any time before sending an IR frame. See also [Compile options / macros for this library](https://github.com/Arduino-IRremote/Arduino-IRremote#compile-options--macros-for-this-library).

| `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. |
|
||||
| `RECORD_GAP_MICROS` | 5000 | Minimum gap between IR transmissions, to detect the end of a protocol.<br/>Must be greater than any space of a protocol e.g. the NEC header space of 4500 µs.<br/>Must be smaller than any gap between a command and a repeat; e.g. the retransmission gap for Sony is around 24 ms.<br/>Keep in mind, that this is the delay between the end of the received command and the start of decoding. |
|

| `IR_INPUT_IS_ACTIVE_HIGH` | disabled | Enable it if you use a RF receiver, which has an active HIGH output signal. |
|
||||
| `IR_SEND_PIN` | disabled | If specified (as constant), it reduces program size and improves send timing for AVR. If you want to use a variable to specify send pin e.g. with `setSendPin(uint8_t aSendPinNumber)`, you must not use / disable this macro in your source. |

|
||||
| `SEND_PWM_BY_TIMER` | disabled | Disables carrier PWM generation in software and use hardware PWM (by timer). Has the advantage of more exact PWM generation, especially the duty cycle (which is not very relevant for most IR receiver circuits), and the disadvantage of using a hardware timer, which in turn is not available for other libraries and to fix the send pin (but not the receive pin) at the [dedicated timer output pin(s)](https://github.com/Arduino-IRremote/Arduino-IRremote#timer-and-pin-usage). Is enabled for ESP32 and RP2040 in all examples, since they support PWM gereration for each pin without using a shared resource (timer). |
|
||||
| `USE_NO_SEND_PWM` | disabled | Uses no carrier PWM, just simulate an **active low** receiver signal. Used for transferring signal by cable instead of IR. Overrides `SEND_PWM_BY_TIMER` definition. |

| `IR_SEND_DUTY_CYCLE_PERCENT` | 30 | Duty cycle of IR send signal. |
