My Custom RTOS Kernel for Smart Parking Management on STM32F401VE is a lightweight, preemptive real‑time kernel engineered specifically for ARM Cortex‑M4 microcontrollers. Designed with automotive‑grade precision in mind, this scheduler provides deterministic task management, minimal latency, and an ultra‑small memory footprint, making it ideal for embedded control in smart Parking management systems. The scheduler core is written in C, ensuring portability across all Cortex‑M4 devices, and features:
- Priority‑based Scheduling: Implements a fixed‑priority preemptive algorithm with round‑robin time slicing to guarantee timely task execution.
- Dynamic Task Management: Supports runtime task creation, deletion, and priority adjustment for flexible application workflows.
- Inter‑Task Synchronization: Includes mutexes, semaphores, and event flags to coordinate resource sharing without race conditions.
- Low Overhead: Optimized context switch routines and configurable tick rates yield a minimal RAM and flash footprint.
This project comes with comprehensive documentation, example integrations for smart car sensor and actuator modules, and a modular architecture that allows easy extension or adaptation to other Cortex‑M4 platforms.
- Target Platform: STM32F401VE (ARM Cortex‑M4) and compatible Cortex‑M4 MCUs.
- Use Case: Embedded control for smart Parking management, including real‑time sensor sampling, actuator control, and communication scheduling.
- Language & Toolchain: C (GNU11), GNU Arm Embedded Toolchain (arm-none-eabi-gcc), CMSIS-compliant startup code.
This update adds a dedicated Project File Structure section to clearly document the repository layout, and refines the Getting Started instructions to align with that structure—covering cloning, configuration, build, and flash steps using CMake and the GCC ARM Embedded toolchain.
