Developing IoT Projects with ESP32

By: Vedat Ozan Oner

Overview of this book

Developing IoT Projects with ESP32 provides end-to-end coverage of secure data communication techniques from sensors to cloud platforms that will help you to develop production-grade IoT solutions by using the ESP32 SoC. You'll learn how to employ ESP32 in your IoT projects by interfacing with different sensors and actuators using different types of serial protocols. This book will show you how some projects require immediate output for end-users, and cover different display technologies as well as examples of driving different types of displays. The book features a dedicated chapter on cybersecurity packed with hands-on examples. As you progress, you'll get to grips with BLE technologies and BLE mesh networking and work on a complete smart home project where all nodes communicate over a BLE mesh. Later chapters will show you how IoT requires cloud connectivity most of the time and remote access to smart devices. You'll also see how cloud platforms and third-party integrations enable endless possibilities for your end-users, such as insights with big data analytics and predictive maintenance to minimize costs. By the end of this book, you'll have developed the skills you need to start using ESP32 in your next wireless IoT project and meet the project's requirements by building effective, efficient, and secure solutions.

Chapter 3: Impressive Outputs with Displays

Some IoT products require an immediate visual output to end users; for example, a smart thermostat needs to have a display to show setpoints. In this chapter, we will talk about different display types that we can use together with ESP32 and how to select a display for a given set of requirements by discussing the pros and cons. There are several display technologies available on the market with different features and it is important to know about them so as to select the right one when necessary.

Another subject that we are going to learn is FreeRTOS, which is the official RTOS supported by ESP32. In actual fact, we have already used several FreeRTOS functions in the examples, but there is more to learn with a view to developing real-world products.

In this chapter, we're going to cover the following main topics:

  • Using LCDs
  • Interfacing with OLED displays
  • TFT displays for superior graphics
  • Using FreeRTOS
  • ...
