FreeRTOS - Task Priorities

Consider the following code snippet:

TaskHandle_t xTask1;
// Assume xTask1 is created with priority 2
vTaskPrioritySet(xTask1, 5);
UBaseType_t newPriority = uxTaskPriorityGet(xTask1);
printf("%u", newPriority);

What will be printed?

A0

B2

C5

DCompilation error

Step-by-Step Solution

Solution:

Step 1: Understand priority change
The call vTaskPrioritySet(xTask1, 5) changes the task's priority from 2 to 5.
Step 2: Check the priority retrieval
uxTaskPriorityGet(xTask1) returns the current priority, which is now 5.
Final Answer:
5 -> Option C
Quick Check:
Priority updated to 5, so output is 5 [OK]

Quick Trick: Priority changes immediately, so get returns new value [OK]

Common Mistakes:

Assuming priority stays the same after set
Confusing priority with task handle
Thinking printf prints task handle
