11.5.1. Task Management

Try these first

1. 1.

   Define what a task is in the context of CMSIS-RTOS.

   Hint

   Think about what role the RTOS plays in scheduling work.

2. 2.

   What does interrupt handling refer to?

   Hint

   Consider situations when the processor needs to focus on urgent events.

3. 3.

   What is the main function of CMSIS-RTOS?

   • To manage power consumption
   • To provide a standardized API for task management
   • To increase code size

   Hint

   Think about the primary role of operating systems in programming.

4. 4.

   True or False: Interrupt handling allows tasks to run even when they are not prioritized.

   • True
   • False

   Hint

   Consider the definition and significance of priority in task management.

5. 5.

   Design a simple RTOS scenario involving three tasks: one for monitoring temperature, one for controlling a fan, and one for logging data. How would you prioritize these tasks and why?

   Hint

   Consider how quickly each task needs to respond to events.

6. 6.

   What would happen if two tasks try to access a shared resource without synchronization? Provide an example and suggest a solution using semaphores.

   Hint

   Think about the consequences of unpredictable interactions between tasks.
