- RTOS Overview
- RTOS is a specialized operating system for real-time applications
- It ensures deterministic behavior and task scheduling within time constraints
- RTOS manages context switching and resource sharing among tasks
- FreeRTOS Features
- Open-source real-time operating system kernel developed by Richard Barry
- Provides preemptive multitasking with priority-based scheduling
- Supports STM32 family and offers synchronization mechanisms
- Has minimal memory overhead and active community support
- Implementation Details
- CMSIS-RTOS library enables FreeRTOS control through STM32CubeIDE
- Project setup requires configuring CMSIS_V2 interface and enabling USE_PREEMPTION
- Two tasks created with different priorities and stack sizes
- SysTick timer used for operating system tasks
- Project Example
- Demonstrates LED blinking at different speeds based on task priority
- Uses osDelay function instead of HAL_Delay for non-blocking operations
- Two LEDs blink simultaneously with 500ms delay between tasks
- Project successfully implemented on STM32 NUCLEO-F446RE board
