FreeRTOS - Design Patterns for RTOSWhat is the primary role of an event group in FreeRTOS event-driven architecture?ATo allocate memory dynamically for tasksBTo synchronize tasks by setting and waiting for event bitsCTo manage hardware interrupts directlyDTo schedule tasks based on priority onlyCheck Answer
Step-by-Step SolutionSolution:Step 1: Understand event groups in FreeRTOSEvent groups are used to synchronize tasks by setting and waiting for bits representing events.Step 2: Compare options with event group roleOnly To synchronize tasks by setting and waiting for event bits correctly describes event groups' role in synchronization using event bits.Final Answer:To synchronize tasks by setting and waiting for event bits -> Option BQuick Check:Event group role = Synchronization [OK]Quick Trick: Event groups sync tasks using bits, not memory or interrupts [OK]Common Mistakes:Confusing event groups with memory managementThinking event groups handle interruptsAssuming event groups only schedule by priority
