11.5.3. Interrupt Handling in RTOS

Try these first

1. 1.

   What does ISR stand for?

   Hint

   Think about what happens when an interrupt occurs.

2. 2.

   What is the purpose of NVIC?

   Hint

   Consider the role of the controller in processing interrupts.

3. 3.

   What is the main function of the NVIC?

   • To enable timers
   • To manage interrupt priorities
   • To communicate with peripherals

   Hint

   Remember the role of this controller in embedded systems.

4. 4.

   True or False: All interrupts are handled immediately and block all other processing until completed.

   • True
   • False

   Hint

   Think of a waiter balancing multiple orders.

5. 5.

   Design a small embedded system that interfaces a temperature sensor with an MCU using interrupts. Detail how you would manage the interrupts and the functions required.

   Hint

   Think about how events occur and how you would manage the timing to avoid data loss.

6. 6.

   Given a scenario with multiple mice generating interrupts, design a system that prioritizes interrupts based on the importance of the task each mouse represents. Include a flow diagram to visually represent your approach.

   Hint

   Consider the implications of each task and rank them accordingly.
