This project was a lab assignment for ENSE 452 class

The goal of this project is to design an elevator control system using the STM32 Cortex-M3 board with FreeRTOS and hardware interrupts. The system includes a CLI for user interaction to control elevator operations such as floor selection, door opening, door closing, and maintenance mode activation.

• Using the STM32 Cortex-M3 hardware peripherals (GPIO, USART2, Timer2).
• Implement a multitasking environment with FreeRTOS.
• Enable inter-task and ISR-task communication via FreeRTOS queues.
• Provide a user-friendly CLI for runtime control and testing.

1. CLI Commands:

• 1, 2, 3, 4: Select floors.
• o, c: Open and close doors.
• M: Activate maintenance mode.

2. Tasks:

• StatusWindowTask Increase the time per seconds and update the status window (Top side of terminal).
• ProcessUserInputTask Handles user input via CLI.
• StartDefaultTask Manages emergency button states.

3. Interrupts:

• Emergency Button Triggered by EXTI0_IRQHandler to enter emergency mode.
• UART Communication Processes user commands.
