Logic Analyzers in Practice

Step-by-step instructions guide you through the analysis of modern protocols such as I2C, SPI, UART, RS-232, NeoPixel, WS28xx, HD44780 and 1-Wire protocols. With the help of numerous experimental circuits based on the Raspberry Pi Pico, Arduino Uno and the Bus Pirate, you will learn the practical application of popular USB logic analyzers.



All the experimental circuits presented in this book have been fully tested and are fully functional. The necessary program listings are included — no special programming or electronics knowledge is required for these circuits. The programming languages used are MicroPython and C along with the development environments Thonny and Arduino IDE.



This book uses several models of flexible and widely available USB logic analyzers and shows the strengths and weaknesses of each price range. You will learn about the criteria that matter for your work and be able to find the right device for you.



Whether Arduino, Raspberry Pi or Raspberry Pi Pico, the example circuits shown allow you to get started quickly with protocol analysis and can also serve as a basis for your own experiments.



After reading this book, you will be familiar with all the important terms and contexts, conduct your own experiments, analyze protocols independently, culminating in a comprehensive knowledge set of digital signals and protocols.



"I am an electronics technician and work intensively with electronics in my professional environment as well as privately, dealing with analog and digital robots, computers, amateur radio, circuit design and circuit board layouts, microcontrollers... Did a lot of soldering and troubleshooting and faultfinding, repaired many things conducting electricity, and often failed. But I have always enjoyed recording my experiences and passing on my knowledge."
