I am not sure that Attachinterrupt is MegatinyCore specific. It seems a generic Arduino function that has it's own reference documentation overhere
It has an example, including the mentioned "digitalPinToInterrupt"
const byte ledPin = 13;
const byte interruptPin = 2;
volatile byte state = LOW;
void setup() {
pinMode(ledPin, OUTPUT);
pinMode(interruptPin, INPUT_PULLUP);
attachInterrupt(digitalPinToInterrupt(interruptPin), blink, CHANGE);
}
void loop() {
digitalWrite(ledPin, state);
}
void blink() {
state = !state;
}
For several days I have been struggling with an ATTiny3216 to understand why in standby, when I use attachInterrupt I have 200µA of consumption when I should only have 2µA. In fact I was using the function like this: attachInterrupt(PIN_PA5, myFunc, FALLING) while it should be used like this: attachInterrupt(digitalPinToInterrupt(PIN_PA5), myFunc, FALLING) the first parameter is named "pin", for me it seemed logical. the documentation should be improved and an example put
