UART

Our microcontroller (like most) has a peripheral called a UART (for "Universal Asynchronous Receiver/Transmitter). This peripheral can be configured to work with several serial communication protocols. The peripheral we will be working with is named UARTE (for "UART with Easy DMA", a topic outside the scope of this chapter).

Throughout this chapter, we'll use serial communication to exchange information between the microcontroller and your computer.
