|
||||
|
||||
Every pin can be used for receiving.<br/>
|
||||
If software PWM is selected, which is default, every pin can also be used for sending. Sending with software PWM does not require a timer!
|

|

The TinyReceiver example uses the **TinyReceiver** library, which can **only receive NEC codes, but does not require any timer** and runs even on a 1 MHz ATtiny85.
|
||||
|

The code for the timer and the **timer selection** is located in [private/IRTimer.hpp](https://github.com/Arduino-IRremote/Arduino-IRremote/blob/master/src/private/IRTimer.hpp). It can be adjusted here.<br/>
