HS_DataLog can stream sensor data via USB or store them into an SD Card.
When using the SD Card, it is possible to select between the "continuous" or the "intermittent" modes just by changing the HSD_SD_LOGGING_MODE define in main.h file.
Continuous Mode
#define HSD_SD_LOGGING_MODE HSD_SD_LOGGING_MODE_CONTINUOUS
Press the USR button to start and stop the acquisition.
Data are stored in a single folder, one single file for each sensor for the complete duration of the acquisition.
Intermittent Mode
#define HSD_SD_LOGGING_MODE HSD_SD_LOGGING_MODE_INTERMITTENT
The acquisition can be started/stopped by pressing the USR button.
In this case the acquisition is not continuous and for each cycle:
1- A new folder is created (STWIN_###)
2- Data are stored in the new folder, one file for each sensor. The acquisition lasts for the amount of seconds defined by the user --> HSD_LOGGING_TIME_SECONDS_ACTIVE
3- The acquisition is then paused for the amount of seconds defined by the user --> HSD_LOGGING_TIME_SECONDS_IDLE
4- back to step 1
The duty cycle parameters can be changed in sdcard_manager.h file:
#if (HSD_SD_LOGGING_MODE == HSD_SD_LOGGING_MODE_INTERMITTENT)
/* Define the duty cycle of the data logging */
#define HSD_LOGGING_TIME_SECONDS_IDLE 5
#define HSD_LOGGING_TIME_SECONDS_ACTIVE (15*60 - HSD_LOGGING_TIME_SECONDS_IDLE)
#endif
Hope it helps
