Struct AdcCalLine 

pub struct AdcCalLine<ADCX> { /* private fields */ }

Available on crate feature unstable only.

Line fitting ADC calibration scheme.

This scheme implements gain correction based on reference points, and returns readings in mV.

A reference point is a pair of a reference voltage and the corresponding mean raw digital ADC value. Those values are stored in eFuse bit fields for each supported attenuation, and there is no way to establish them at runtime: the ADC can only be switched to internal ground, which gives the zero-voltage offset rather than a second point to derive a gain from.

This scheme also includes basic calibration (AdcCalBasic).

Errors

Returns Error::UnsupportedAttenuation if the attenuation has no reference point on this chip, or Error::MissingCalibrationData if the chip carries no line-fitting calibration data or the stored reference point is zero.
