Function Documentation
◆ adc_calibrate()
| int adc_calibrate | ( | uint64_t | duration | ) |
Perform RocketLogger ADC reference voltage calibration.
Run a measurement without data output to file or web for the given duration. Resets the sampling status to default after completion.
- Parameters
-
duration The duration of the calibration run in seconds
- Returns
- Measurement run return value, 0 on success, negative on failure with errno set accordingly
