FreeRTOS - Design Patterns for RTOS

What is the main benefit of using event-driven architecture in FreeRTOS?

AIt makes the program run all tasks continuously without waiting.

BIt requires more CPU power to check all events constantly.

CThe program reacts only when an event occurs, saving CPU time.

DIt disables multitasking to focus on one task at a time.

Step-by-Step Solution

Solution:

Step 1: Understand event-driven architecture basics
Event-driven architecture means the program waits and reacts only when events happen, not running tasks all the time.
Step 2: Connect to FreeRTOS event groups
FreeRTOS event groups let tasks wait efficiently for events, saving CPU time by not running unnecessarily.
Final Answer:
The program reacts only when an event occurs, saving CPU time. -> Option C
Quick Check:
Event-driven = React on event, save CPU [OK]

Quick Trick: Event-driven means react only on events, not always running [OK]
