CS-328 Embedded Systems includes lab work covering interrupt programming and hands-on data logging applications, such as logging temperature data to an SD card, giving students practical experience with the specialized programming concerns unique to embedded systems — hardware-constrained devices that run dedicated software for a specific function.
Interrupt programming as an embedded-specific concept
The course covers interrupt programming specifically because embedded systems must respond to real-time hardware events (a sensor reading, a button press) efficiently, a concern that doesn't arise the same way in typical application-level software development.
Hands-on data logging as a practical embedded application
CS-328's hands-on data logging project (such as logging temperature data to an SD card) grounds embedded systems theory in a genuine, practical application, reflecting the kind of real-world task embedded systems are actually built to perform.

Worked example: why interrupts matter for embedded systems
- Without interrupts: The system must continuously check whether an event (like a sensor trigger) has occurred, wasting processing resources
- With interrupt programming: The system responds immediately and efficiently only when the event actually occurs
- Lesson: CS-328 teaches that interrupt programming is essential for embedded systems, which often operate under tight hardware and power constraints that make constant checking impractical

Frequently asked questions
Embedded systems typically operate under real hardware constraints — limited processing power, limited battery life — making constant, continuous checking for hardware events impractical and wasteful, so interrupt programming (responding immediately and only when an event actually occurs) is a fundamentally different and more efficient approach specific to this hardware-constrained context. CS-328 covers interrupts because they represent a genuinely distinct programming concern that typical application-level software development, running on resource-abundant computers, doesn't usually need to address in the same way.
Embedded systems concepts like interrupt handling and hardware-software interaction become genuinely concrete and demonstrable when applied to a real practical task — reading a sensor, processing the data, and writing it reliably to storage — giving students direct experience with the kind of real-world function embedded systems are actually built to perform. CS-328 uses this hands-on project because embedded systems competency is fundamentally practical, requiring genuine hardware interaction experience, not just conceptual understanding of interrupts and constraints.
