8.2.3.3. Interrupts

Try these first

1. 1.

   What is an interrupt?

   Hint

   Think of how alarms alert you.

2. 2.

   Name one type of interrupt.

   Hint

   Consider what timers in embedded systems do.

3. 3.

   What is the primary purpose of interrupts in embedded systems?

   • To enhance graphics rendering
   • To enable CPU responsiveness
   • To manage power consumption

   Hint

   Remember their role in responding to events quickly.

4. 4.

   True or False: A GPIO interrupt occurs when there is a change in the input signal.

   • True
   • False

   Hint

   Think back to how buttons trigger events.

5. 5.

   Design an embedded system that monitors both temperature and humidity. Implement timer and GPIO interrupts effectively.

   Hint

   Consider how timing and immediate responses are vital together.

6. 6.

   What potential issues can arise in an embedded system if interrupts are not clearly prioritized?

   Hint

   Think about how unaddressed signals could affect safety or functionality.
