Development of FM Radio with LCD Display: A Detailed Design Process

Follow the journey of programmers Devin Wagner and Shawn McKinley as they build an FM Radio from scratch, using the Si4703 FM Receiver and ATMEGA88PA microcontroller instead of Arduino or ATTINY45. Learn about the hardware components and software development process involving I2C, register interactions, and continuous write/read operations in C language. Experience the debugging phases and the final assembly of the project. This detailed account provides valuable insights into designing complex electronic systems.
