You are designing a Resource Manager Task to handle both sensor read and actuator write requests. Which data structure design best supports efficient request differentiation and processing?

hard📝 Application Q8 of 15

FreeRTOS - Design Patterns for RTOS

AUse separate queues for read and write requests

BUse a struct with a command type field and a union for read/write data

CUse a single integer field to encode both command and data

DUse global variables to store request type and data separately

Step-by-Step Solution

Solution:

Step 1: Requirement for request differentiation
The task must distinguish request types efficiently.
Step 2: Struct with command and union
A struct with a command field and union allows compact, clear representation of different data types.
Step 3: Evaluate other options
Separate queues add complexity; encoding in one int is error-prone; globals reduce modularity.
Final Answer:
Struct with command and union -> Option B
Quick Check:
Use command field plus union for varied request data [OK]

Quick Trick: Use command field plus union for multiple request types [OK]

Common Mistakes:

Using multiple queues unnecessarily
Encoding multiple data in one integer
Relying on global variables for request data
