FreeRTOS - Task Scheduling

Which of the following is the correct way to create a task with priority 3 in FreeRTOS?

AxTaskCreate(taskFunction, "Task1", 1000, NULL, -1, NULL);

BxTaskCreate(taskFunction, "Task1", 1000, NULL, 0, NULL);

CxTaskCreate(taskFunction, "Task1", 1000, NULL, 3, NULL);

DxTaskCreate(taskFunction, "Task1", 1000, NULL, 10, NULL);

Step-by-Step Solution

Solution:

Step 1: Understand xTaskCreate parameters
The fifth parameter is the task priority; valid priorities are non-negative integers within configMAX_PRIORITIES.
Step 2: Check options for valid priority
xTaskCreate(taskFunction, "Task1", 1000, NULL, 3, NULL); uses priority 3, which is valid. xTaskCreate(taskFunction, "Task1", 1000, NULL, 0, NULL); uses 0 (lowest priority), C uses -1 (invalid), D uses 10 (may be invalid if max priorities < 11).
Final Answer:
xTaskCreate(taskFunction, "Task1", 1000, NULL, 3, NULL); -> Option C
Quick Check:
Priority parameter is fifth and must be valid integer [OK]

Quick Trick: Priority is the 5th parameter in xTaskCreate [OK]
