[Solved] Consider this FreeRTOS code snippet:void vTaskFunction(void *pvParameters) { for (;;) { if (xSemaphoreTake(xSemaphore, 0) ==... } } }What is the state of the task when vTaskDelay() is called? | FreeRTOS

FreeRTOS - RTOS Fundamentals

Consider this FreeRTOS code snippet:

void vTaskFunction(void *pvParameters) {
    for (;;) {
        if (xSemaphoreTake(xSemaphore, 0) == pdTRUE) {
            // Critical section
        } else {
            vTaskDelay(pdMS_TO_TICKS(100));
        }
    }
}

What is the state of the task when vTaskDelay() is called?

ARunning

BReady

CBlocked

DSuspended

Step-by-Step Solution

Solution:

Step 1: Understand vTaskDelay effect
Calling vTaskDelay causes the task to enter Blocked state, waiting for the delay time to expire.
Step 2: Confirm task state during delay
While delayed, the task is not Ready or Running; it is Blocked until the timer expires.
Final Answer:
Blocked -> Option C
Quick Check:
vTaskDelay = Blocked state [OK]

Quick Trick: vTaskDelay puts task in Blocked state [OK]

Common Mistakes:

Thinking delay means Ready
Confusing Blocked with Suspended
Assuming task runs during delay
