[Solved] Consider this code snippet inside a FreeRTOS task: for (;;) { printf("Tick\n"); vTaskDelay(100); } If the tick rate is 1 kHz (1 ms per tick), what is the approximate time between each "Tick" print? | FreeRTOS

FreeRTOS - Task Scheduling

Consider this code snippet inside a FreeRTOS task:

for (;;) {
  printf("Tick\n");
  vTaskDelay(100);
}

If the tick rate is 1 kHz (1 ms per tick), what is the approximate time between each "Tick" print?

A100 milliseconds

B1 second

C10 milliseconds

D1000 milliseconds

Step-by-Step Solution

Solution:

Step 1: Understand tick rate and delay
Tick rate is 1 kHz, so 1 tick = 1 millisecond. Delay is 100 ticks.
Step 2: Calculate delay time
100 ticks * 1 ms/tick = 100 milliseconds delay between prints.
Final Answer:
100 milliseconds -> Option A
Quick Check:
Tick rate 1kHz * 100 ticks = 100 ms delay [OK]

Quick Trick: Multiply ticks by tick period (ms) for delay time [OK]
