Which details about FreeRTOS tasks can be obtained by using the vTaskList() function?
ACPU temperature and voltage levels
BOnly task names and their creation time
CMemory usage of each task exclusively
DTask name, state, priority, stack usage, and task number
Step-by-Step Solution
Solution:

  1. Step 1: Understand vTaskList()

    The vTaskList() function provides a snapshot of all tasks currently managed by the FreeRTOS kernel.

  2. Step 2: Identify the information provided

    It outputs task name, current state (e.g., Running, Blocked), priority, stack high water mark (stack usage), and task number.

  3. Final Answer:

    Task name, state, priority, stack usage, and task number -> Option D

  4. Quick Check:

    Check official FreeRTOS documentation for vTaskList() output format [OK]
Quick Trick: vTaskList shows task details including state and stack [OK]
Common Mistakes:
  • Assuming it only shows task names
  • Thinking it reports CPU or hardware metrics
  • Confusing it with memory profiling functions
