What Will I Learn?

• What is I2C, UART, SPI and Onewire?
• Analysis and discussion of data sheets
• Understanding and using bit operations
• Analysis of external libraries for understanding control
• Evaluating sensors without external libraries
• Protocol Reverse Engineering
• Understand the different communication protocols such as UART, I2C, OneWire and SPI and explain how they work.
• To analyse the advantages and disadvantages of the different protocols and select the appropriate protocols for specific use cases.
• To successfully establish serial communication between Arduino and ESP microcontrollers and implement data transfers between them.
• To recognise and analyse non-standard protocols and integrate them into own Arduino and ESP projects to meet specific requirements.

Requirements

• Logic Analyzer for analysing the logs with PulseView (Windows, macOS & Linux)
• Arduino or ESP32
• First experience with programming Arduinos and ESPs. You should already know how to use the IDE.
• Various sensors for evaluating protocols such as DHT20, DHT11, BH1750. More details in the parts list
• Fun with the analysis of protocols

Target audience

• Arduino and ESP hobbyists
• Electronics and IoT enthusiasts
• Programmers and developers: if you already have basic programming skills and want to expand your skills in the field of microcontroller programming
• Anyone who enjoys developing with microcontrollers
