Summary

This chapter introduces embedded systems hardware fundamentals aimed at software engineers. It explains core components, the hardware–software interface, and practical considerations for firmware design and bare‑metal development.

Key Takeaways

• Understand core embedded hardware components: microcontrollers, memory, buses, and common peripherals.
• Explain how the hardware–software interface works, including memory‑mapped I/O and interrupts.
• Apply basic board bring‑up and debugging concepts used when developing firmware.
• Differentiate between bare‑metal development, RTOS use, and when embedded Linux may be appropriate.
• Recognize practical constraints (power, interfaces, and timing) that influence embedded firmware design.

Who Should Read This

Software engineers and firmware developers new to embedded systems, or experienced programmers transitioning to hardware‑facing roles who need a concise foundation in hardware for writing better firmware.
