Hello,
Is there an example of implementation of UART interrupt that activate a function that handle data coming on the RX line?

thx

why? The hardware takes care of all that for you.

Data that comes into the RX pin already causes an interrupt. That interrupt reads the data into the serial receive buffer. If you use the available() function to check if the buffer contains data regularly (each non-blocking loop()), you will not miss data.

One example, for an Arduino UNO, is the HardwareSerial parts of the Arduino core.

HardwareSerial.h
HardwareSerial.cpp
