The MKR WiFi 1010 seems unable to have an I2C address assigned. as the code halts. If no address is assigend in Wire.begin(), it works.
// Wire Slave Receiver

// Demonstrates use of the Wire library
// Receives data as an I2C/TWI slave device
// Refer to the "Wire Master Writer" example for use with this

#include <Wire.h>
void setup()
{
Wire.begin(10); // join i2c bus with address #4
Wire.onReceive(receiveEvent); // register event
Serial.begin(9600); // start serial for output
pinMode(13,OUTPUT);
}
void loop()
{
delay(100);
digitalWrite(13,HIGH);
delay(100);
digitalWrite(13,LOW);
}
// function that executes whenever data is received from master
// this function is registered as an event, see setup()
void receiveEvent(int howMany)
{
while(1 < Wire.available()) // loop through all but the last
{
char c = Wire.read(); // receive byte as a character
Serial.print(c); // print the character
}
int x = Wire.read(); // receive byte as an integer
Serial.println(x); // print the integer
}
