SW pin usage in SX1262 and ATmega328 #1

This is more of question. Where is this library functionality used for SW pin in SX1262 wiring to ATmega328 PB1?

Please advise.

The library does not use the SW Pin. In my case it is directly connected to Vcc, so there is no need to handle it in the lib (please see my schematic). I will add a FAQ to the readme, thanks!

In more detail: The SW Pin enables the RF Switch. In low power applications SW is connected to the Pin DIO2 of SX126x and the SX126x then switches RF on during TX automatically if configured appropriate. Please see the SX126x Spec and search for "SetDio2AsRfSwitchCtrl" My lib currently does not support this. If you like to contribute: You may like to add a 5th parameter to the constructor (bool true/false). This seems the right place for me. true: DIO2 switches RF, false: RF controlled externally. To fit my schematic I would then set this param to false and it should do.
