Detailed Description

API function of simpleFileSystem The API functions are divided in:

• low level API
• high level API

Low level API

• interface between sFS logic and memory implementation
• contains of elementary operations with memory
• almost every function is read/write operations
• the final memory driver selection in in file FS_lowLevel.h

High level API

• user level functions with simple File system
• user level functions with file manipulating

List of functions:

• File system related functions
  • FS_init() - Init the sensorFS filesystem.
  • FS_create_file() - Begin file creation procedure. No write to FLASH is perform.
  • FS_open_file() - Try open to file with given ID.
  • FS_open_last_file() - Open last file on sensorFS.
  • FS_write_preamble() - Write preamble aprt in sensorFS, if not exists.
  • FS_num_files() - Return number of files.
  • FS_detect_num_files() - Read number of files.
  • FS_commit_file_header() - Finish write information about created file.
  • FS_is_empty() - Check, that sensorFS/FLASH is empty.
  • FS_sensor_driver() - Return driver for attached sensor.
• File related functions
  • file_add_sensor() - Add new sensor to created file.
  • file_get_num_parts() - Return number parts of opened file.
  • file_data_row_begin() - Initialize internal data structures for new data record.
  • file_store_data() - Prepare measured value to file buffer.
  • file_data_row_commit() - Write prepared measured values
  • file_record_length() - Return length of record.
  • file_column_format() - Return format of i-th sensor in datafile.
  • file_size() - Return file size in Bytes.
