FreeRTOS - Task Scheduling

Which of the following is the correct syntax to call vTaskDelayUntil() inside a task loop?

AvTaskDelayUntil(&lastWakeTime, &delayTicks);

BvTaskDelayUntil(lastWakeTime, &delayTicks);

CvTaskDelayUntil(&lastWakeTime, delayTicks);

DvTaskDelayUntil(lastWakeTime, delayTicks);

Step-by-Step Solution

Solution:

Step 1: Understand parameter types
vTaskDelayUntil() expects a pointer to TickType_t for last wake time and a tick count value for delay.
Step 2: Match correct argument passing
The first argument must be address of lastWakeTime (&lastWakeTime), second argument is delayTicks (value).
Final Answer:
vTaskDelayUntil(&lastWakeTime, delayTicks); -> Option C
Quick Check:
Pointer first, value second [OK]

Quick Trick: Pass pointer to lastWakeTime, value for delay [OK]
