- * \brief Simple application that implement a log device, running on the AT91SAM7X-EK board.
- *
- * The main scope of this application is to show you how use the SD memory card and read and write
- * settings and logs. Thanks the ini parser module we can read settings, stored on memory card,
- * and change the application behaviour.
- * Generally the application work in this way:
- * - Try to access to SD memory card, if it is present we read the inifile
- * - If we have read correctly from SD, we compute the value that we want log
- * (temperature, pressure and supplay voltage)
- * - If we have enable (from ini file) to log on the file we write the log on it.
- * - If we have enable (from ini file) to log on the serial we write the log on it.
- * - wait the sample_time (from ini file)
- * - contine from beginning.
- *
- * Here we put the ini file that this example uses. To use it copy
- * the folling configutation line into the file called sd_fat.ini (or see INI_FILE_NAME
- * define if you want chande the name).
- * \code
- *
- * # Bertos SD fat project example
- * #
- * # Basic configurarion
- * #
- *
- * [log]
- * # Name of log file
- * name = test.log
- * # Enable the logging on serial device (enable = 1, disable = 0)
- * log_on_serial = 1
- * # Enable logging on sd file (enable = 1, disable = 0)
- * log_on_file = 1
- * # Period between two log in millisecond
- * sample_time = 1000
- *
- * [serial_log]
- * # Select serial port where log
- * port = 0
- * # Serial port baudrate
- * baud = 115200
- *
- * [log_format]
- * # Default text to insert on each log line
- * line_header = BeRTOS Log:
- * # Use this char to separate each log field
- * field_sep = ;
- *
- * [temperature]
- * unit_label = C
- *
- * [pressure]
- * unit_label = hPa
- *
- * [voltage]
- * unit_label = V
