[Solved] Which of the following is the correct way to declare a task using static allocation in FreeRTOS? — Ans: xTaskCreateStatic(TaskFunction, "Task", 100, NULL, 1, stackBuffer, &taskBuffer); | FreeRTOS

FreeRTOS - Memory Management

Which of the following is the correct way to declare a task using static allocation in FreeRTOS?

AxTaskCreateStatic(TaskFunction, "Task", 100, NULL, 1, stackBuffer, &taskBuffer);

BxTaskCreate(TaskFunction, "Task", 100, NULL, 1, NULL);

CxTaskCreateDynamic(TaskFunction, "Task", 100, NULL, 1, &taskHandle);

DxTaskCreateStatic(TaskFunction, "Task", 100, NULL, 1, NULL, NULL);

Step-by-Step Solution

Solution:

Step 1: Identify static allocation function
FreeRTOS provides xTaskCreateStatic for static allocation, requiring stack and task buffers.
Step 2: Check parameters
xTaskCreateStatic(TaskFunction, "Task", 100, NULL, 1, stackBuffer, &taskBuffer); correctly passes stackBuffer and taskBuffer pointers. xTaskCreate uses dynamic allocation. There is no xTaskCreateDynamic function. Passing NULL buffers is incorrect.
Final Answer:
xTaskCreateStatic(TaskFunction, "Task", 100, NULL, 1, stackBuffer, &taskBuffer); -> Option A
Quick Check:
Static task creation needs buffers [OK]

Quick Trick: Use xTaskCreateStatic with buffers for static tasks [OK]
