Eventually, a beginner learns how the MCU talks to other chips using protocols like UART (serial), I2C , and SPI . 4. The Development Environment
Most embedded programs do not "exit." They consist of an initialization phase followed by an infinite while(1) loop that constantly checks for inputs (like a button press) and updates outputs. Eventually, a beginner learns how the MCU talks
This is the most basic form of interaction. Beginners learn to configure pins as inputs to read digital signals or outputs to drive external components. Eventually, a beginner learns how the MCU talks
