In this chapter, we will delve deep into the world of I²C, also known as the Two-Wire Interface, TWI, in the Arduino world. This is quite a complicated system in which to use interrupts, but it can be done. This chapter starts easily with a discussion on device addresses – which occasionally can lead to confusion – followed by a simple polled example. This is then expanded to create a sketch using TWI to read and write from and to a temperature sensor before fully expanding our discussion to implement, with a little ...
