Overview of this book

ESP32 is a versatile microcontroller and a great starting point for anyone venturing into the IoT realm, but its configuration and interfacing of sensors can be challenging for new users. Arduino Integrated Development Environment (IDE) simplifies programming, uploading code, and utilization of ESP32 capabilities, enabling users to incorporate it into their IoT projects with ease. This book will help you learn the essentials of sensing, networking, data processing, and applications with ESP32, laying a strong foundation for further IoT development. Starting with ESP32 and Arduino Ide 2.0 basics, you'll first explore practical implementation examples of interfacing sensors with ESP32. These examples will also teach you how to interface the ESP32 camera and display modules with ESP32. As you progress, you’ll get to grips with IoT network and data protocols, as well as the many options they unlock within IoT applications. The book will also help you leverage your newly acquired knowledge with exciting projects ranging from smart connected devices to data loggers and automation. By the end of this book, you'll confidently navigate ESP32 projects with newfound knowledge and skills, know what IoT protocol to select for your applications, and successfully build and deploy your own IoT projects.

Understanding SPI communication

SPI is a synchronous serial communication protocol widely used for connecting microcontrollers or other digital devices with peripheral devices. It provides a straightforward and efficient means of data transfer, making it suitable for applications that require high-speed and full- duplex communication.

Like the I2C communication protocol, the SPI protocol uses a master-slave architecture, where one device acts as a master, controlling the communication, and one or more devices act as slaves, responding to commands from the master.

In this section, we will explore the following topics related to the SPI communication and ESP32:

  • How SPI communication works
  • SPI communication example using ESP32
  • Sensors or devices that use SPI communication

By the end of this section, you will be able to understand what the SPI communication protocol is, how it works, how we can use it in ESP32-based projects, and some common peripherals in...
