FreeRTOS - Design Patterns for RTOS

Examine this heartbeat task code:

void HeartbeatTask(void *pvParameters) {
  while(1) {
    printf("Heartbeat\n");
    vTaskDelay(1000);
  }
}

What is the issue with this implementation?

Awhile(1) loops are not allowed in FreeRTOS tasks

Bprintf cannot be used inside FreeRTOS tasks

CvTaskDelay argument should be in ticks, not milliseconds

DMissing task notification to unblock the task

Step-by-Step Solution

Solution:

Step 1: Check vTaskDelay usage
vTaskDelay expects ticks, not milliseconds.
Step 2: Identify correct usage
Use pdMS_TO_TICKS(1000) to convert ms to ticks.
Final Answer:
vTaskDelay argument should be in ticks, not milliseconds -> Option C
Quick Check:
Always convert ms to ticks for vTaskDelay [OK]

Quick Trick: Convert ms to ticks with pdMS_TO_TICKS [OK]
