X-CUBE-MEMS1 DataLogExtended Example: Key Functions Explained

This is a detailed overview of the key functions found within the DataLogExtended example provided in the X-CUBE-MEMS1 software package:

1. 'main()' - Serves as the main function, responsible for initializing the system and sensors. It also initiates the data logging and storage tasks.

2. 'MX_FREERTOS_Init()' - Initializes the FreeRTOS kernel, providing a real-time operating system foundation for the application.

3. 'MX_GPIO_Init()' - Configures the GPIO pins for various purposes like communication and control.

4. 'MX_I2C1_Init()' - Initializes the I2C1 bus, used to communicate with the sensors.

5. 'MX_USART1_UART_Init()' - Sets up the USART1 serial port for communication, potentially used for debugging or data output.

6. 'BSP_ACCELERO_Init()' - Initializes the accelerometer sensor, responsible for measuring linear acceleration.

7. 'BSP_GYRO_Init()' - Initializes the gyroscope sensor, responsible for measuring angular velocity.

8. 'BSP_MAGNETO_Init()' - Initializes the magnetometer sensor, responsible for measuring magnetic fields.

9. 'startDataLogTask()' - Starts the data logging task, which continuously collects data from the sensors.

10. 'startStorageTask()' - Starts the data storage task, which manages saving the collected data to the SD card.

11. 'DataLogTask()' - The core data logging task. It reads sensor data and forwards it to the storage task for processing.

12. 'StorageTask()' - Handles the storage of sensor data onto the SD card. It receives data from the data logging task and writes it to the storage medium.

13. 'RTC_TimeStampConfig()' - Configures the Real-Time Clock (RTC) to provide time stamps for the collected data.

14. 'RTC_TimeStampIRQHandler()' - Handles interrupts generated by the RTC's time stamping functionality.

15. 'RTC_WakeupIRQHandler()' - Processes interrupts related to the RTC's wake-up functionality.

16. 'RTC_Configuration()' - Sets up the RTC clock and its wake-up time, ensuring the system operates correctly.

17. 'RTC_WakeUpCmd()' - Enables the RTC's wake-up functionality, allowing the system to be powered up at specific times.

18. 'RTC_IRQHandler()' - Handles various interrupts generated by the RTC.

19. 'RTC_GetTimeStamp()' - Retrieves the current time stamp from the RTC.

20. 'RTC_GetCalendar()' - Retrieves the current calendar date and time from the RTC.

21. 'SD_Init()' - Initializes the SD card for data storage operations.

22. 'SD_WriteBlock()' - Writes a block of data to the SD card.

23. 'SD_ReadBlock()' - Reads a block of data from the SD card.
