1 year ago I added "megaavr" to the allowed architectures in library.properties:
...
architectures=avr,esp8266,esp32,stm32,megaavr
...and I was able to send messages using an Arduino Nano Every (ATMega4809).
E.g.
#include <RCSwitch.h>
RCSwitch mySwitch = RCSwitch();
void setup() {
Serial.begin(9600);
// Transmitter is connected to Arduino Every Pin #4
mySwitch.enableTransmit(4);
}
void loop() {
/* Button 3 Toggle */
mySwitch.send(1397076, 24); // Button 3: OFF
delay(1000);
mySwitch.send(1397079, 24); // Button 3: ON
delay(1000);
}Did not do more extensive testing as this fulfilled my requirements.
I just tried to upload a working Arduino sketch (based on your library) to my all new "Arduino NANO Every" (ATmega4809) and im receiving hints / error messages (see below). The Arduino sketch worked fine with my original Arduino UNO and fake Arduino NANO V3 (ATmega328 CH340). I'm using the same sender and receiver - and I also tried the hardware once again with the old Arduinos - so the hardware is OK.
The problem starts already by just trying to open the "examples" of your library - BUT only with the NANO Every!
Here is the hint / warning of the Arduino NANO Every:
