Welcome to the video course "Analysis and use of UART, I2C, OneWire, SPI and non-standard protocols in the Arduino/ESP environment"!
In this course, we dive deep into the world of communication protocols and show you how to use them effectively with Arduino and ESP microcontrollers.
This course is ideal for Arduino and ESP enthusiasts who want to expand their understanding of communication protocols to create complex projects. Whether you are an experienced developer or a beginner, this course will provide you with valuable knowledge and practical applications.
This is not a theory course . We will jump straight into practical implementation and analyse and evaluate the protocols with a logic analyser.
In the course of the course, we will mainly deal with the most important communication protocols in the Arduino environment:
We will also look at non-standard protocols that are often used in special applications. You will learn how to identify, analyse and integrate these protocols into your Arduino and ESP projects.
After the introductory chapter, we are able to handle bit operators so that we can do our evaluations and libraries at bit level.
We will evaluate a light sensor (BH1750), DHT20 and DHT11 as well as an Ikea air quality sensor ourselves, without any external libraries.
In this video course, we will use practical examples and demonstrations to teach you how to use these protocols. You will learn how to set up serial communication between different microcontrollers, transfer data, and read sensors. We will also cover common challenges and troubleshooting that can occur when using these protocols.
By the end of the course, you will have a solid understanding of UART, I2C, OneWire, SPI and non-standard protocols. You will be able to use these protocols safely and effectively in your Arduino and ESP projects and significantly expand your skills as a developer.
