Abstract
Digital communication handles operations to transfer data between a transmitter and receiver(s). As the name implies, the transmitter is the device sending data. The receiver is the device receiving data. The transmitter and receiver can both be microcontrollers or a microcontroller and external peripheral unit. We will consider digital communication operations in this chapter. While doing so, we will start with fundamental definitions. Then, we will handle the most important digital communication types as UART, SPI, I2C, CAN, and USB. We will explain each type starting from its working principles from a general perspective. Then, we will base our setup and usage examples in C, C++, and MicroPython languages in the STM32F4 microcontroller. We will also introduce other digital communication types as secure digital input and output and inter-IC sound. As the end of the chapter application, we will add digital communication ability to the robot vacuum cleaner developed throughout the book.
