In this chapter, we look at using serial communication protocols. In the realm of embedded systems and microcontroller applications, the ability to communicate effectively with external devices is fundamental. Serial communication is the lifeblood of embedded systems, allowing microcontrollers to interact with many external devices and peripherals. The most ubiquitous of these are USART, SPI, and I2C, which I will be explaining in this chapter. ...
