Welcome to this GitHub repository showcasing an advanced embedded system project for MSP430 microcontrollers, programmed in C, leveraging a finite state machine (FSM) for managing a radar detection system. This project is designed for intricate hardware control, making it ideal for educational purposes and advanced embedded development.
- Modular Design: The code is organized into Application (APP), Board Support Package (BSP), Hardware Abstraction Layer (HAL), and Application Programming Interface (API) layers, enhancing both maintainability and scalability.
- Finite State Machine (FSM): Manages system states and transitions for effective control of operational modes, ensuring a robust and responsive system.
- Peripheral Management: Utilizes UART for efficient data transfer between the PC and MCU, facilitating remote control and monitoring of the radar detection system.
- Low Power Management: Implements various low-power modes to optimize power consumption, crucial for battery-operated and energy-efficient applications.
The FSM in this project manages different aspects of system functionality through these states and functions:
- State 0: Idle mode.
- State 1: Control servo motor to a specific angle.
- State 2: Measure distance using the ultrasonic sensor.
- State 3: Perform radar scanning by rotating the servo motor.
- State 4: Script mode to automate tasks.
- State 5: Display LDR measurements on an LCD.
- State 6: Measure LDR values and send data via UART.
- State 7: Reserved for future use.
- State 8: Waiting for new state commands.
