Hai I'm a beginner to Arduino. I was working with the I2C communication b/w two arduinos and I was wondering if there was any way of beginning a communication by the slave. i.e. can the function Wire.onReceive() or Wire.onRequest() -> like the one given in the slave receiver example be used in the code of the master...?
nd I was wondering if there was any way of beginning a communication by the slave
No. A slave can only respond when asked by a master.
Of course, the role of master and slave CAN change.
