The Queue Based Data Passing is an Embedded Systems project that combines Priority management and Scheduler setup, built with Semaphores and queues. The project follows a clean, modular firmware pipeline where input handling, processing, and output control stay separated, making it easy to test, extend, and present. It showcases practical embedded techniques while producing a working, demo-ready device.
Manual control and monitoring for this task is slow, bulky, and cannot respond in real time. Without an embedded approach built on Scheduler setup and Semaphores and queues, users cannot build compact, low-power, responsive systems that interact directly with hardware.
This project applies Embedded Systems techniques through Priority management, orchestrated with Semaphores and queues and Scheduler setup. The firmware is designed for reliability and real-time performance, with clear input, processing, and output layers. It produces consistent, reusable results and can be adapted to related embedded tasks with minimal changes.

Real-time and low-power design
The project is layered: the input layer reads sensors and controls through Priority management; the processing layer runs logic with Semaphores and queues and Scheduler setup; and the output layer drives displays and actuators via Semaphore handling. Shared timing, logging, and driver modules support all layers, keeping the firmware robust and easy to extend.
