[Solved] Given this code snippet, what is the error? void TaskA(void *pvParameters) { while(1) { // Do something vTaskDelay(1000); } } xTaskCreate(TaskA, "TaskA", 1000, NULL, 1, NULL); | FreeRTOS

FreeRTOS - Task Creation and Management

Given this code snippet, what is the error?

void TaskA(void *pvParameters) {
  while(1) {
    // Do something
    vTaskDelay(1000);
  }
}

xTaskCreate(TaskA, "TaskA", 1000, NULL, 1, NULL);

ATask function must return int, not void

BvTaskDelay requires delay in ticks, not milliseconds

CStack size 1000 is too small

DTask name must be longer than 5 characters

Step-by-Step Solution

Solution:

Step 1: Check vTaskDelay parameter
vTaskDelay expects delay in ticks, not milliseconds.
Step 2: Identify correct delay usage
Use pdMS_TO_TICKS(1000) to convert 1000 ms to ticks.
Final Answer:
vTaskDelay requires delay in ticks, not milliseconds -> Option B
Quick Check:
Delay unit must be ticks = vTaskDelay requires delay in ticks, not milliseconds [OK]

Quick Trick: Use pdMS_TO_TICKS() to convert ms to ticks for vTaskDelay [OK]
