I’ve been writing about the USARTs and one might first think that all AVR based Arduino boards can be treated the same. However that is not the case. And since some of the example programs in the (future) book involve two boards communicating with each other, there are a large number of combinations I need …

When considering communication between or among microcontrollers, I’ve discouraged use of the SPI interface because of its lack of a buffered interface in all but the ATmega4809 Ardruino AVR-based boards. However the handshaking protocol built into the I2C standard interface makes I2C communication a safe, reliable choice. (The I2C interface is called TWI in the …
