easy📝 Syntax Q3 of 15
FreeRTOS - Task Scheduling
Which FreeRTOS API function is used to yield the processor voluntarily from a running task?
AvTaskStartScheduler()
BvTaskDelay()
CxTaskCreate()
DvTaskYield()
Step-by-Step Solution
Solution:

  1. Step 1: Recall FreeRTOS task control functions

    vTaskYield() allows a task to give up the CPU voluntarily.

  2. Step 2: Differentiate from other functions

    vTaskDelay() blocks for time, xTaskCreate() creates tasks, vTaskStartScheduler() starts the scheduler.

  3. Final Answer:

    vTaskYield() -> Option D

  4. Quick Check:

    Yield function = vTaskYield() [OK]
Quick Trick: Yield CPU with vTaskYield() function [OK]
Common Mistakes:
  • Using vTaskDelay() to yield
  • Confusing task creation with yielding
  • Thinking scheduler start yields CPU
