Summary

Chapter 7 offers a practical introduction to microcontroller programming and hardware interfacing, covering core peripherals, I/O architectures, and common signal-conditioning needs. It emphasizes the firmware patterns and hardware considerations engineers need to connect sensors and actuators reliably and efficiently.

Key Takeaways

• Describe common MCU peripherals and I/O architectures (GPIO, timers, ADC/DAC, PWM, UART/SPI/I2C) and their practical uses.
• Design signal-conditioning and level-shifting circuits to connect sensors and actuators safely to microcontroller pins.
• Implement interrupt-driven and timer-based firmware patterns for deterministic sampling and control tasks.
• Configure ADC and PWM modules, and manage sampling rates, resolution, and quantization trade-offs for measurements and control.
• Interface serial buses (UART, SPI, I2C) and select appropriate communication protocols for peripherals and external modules.

Who Should Read This
