Struct AdcConversion 

pub struct AdcConversion {
    pub full_scale_voltage: f64,
    pub max_count: f64,
    pub pga_gain: f64,
    pub adc_gain: f64,
}

Parameters for ADC count / voltage conversion.

Describes the digitizer characteristics needed to convert between raw ADC counts and voltage (or physical units with a sensor sensitivity).

Fields

full_scale_voltage: f64

Full-scale range in Volts (e.g. 5.0 for a +/-2.5V ADC)

max_count: f64

Maximum count value: 2^(bits-1) - 1 (e.g. 8388607 for 24-bit)

pga_gain: f64

External PGA (Programmable Gain Amplifier) gain (e.g. 1.0)

adc_gain: f64

Internal digital gain in ADC (e.g. 1.0)

Implementations

impl AdcConversion

pub fn new( full_scale_voltage: f64, bits: u32, pga_gain: f64, adc_gain: f64, ) -> Self

Create from ADC bit depth and gains.

max_count is computed as 2^(bits-1) - 1.

pub fn count_to_voltage(&self, count: f64) -> f64

Convert raw ADC count to input voltage (before PGA).

pub fn voltage_to_count(&self, voltage: f64) -> f64

Convert input voltage to raw ADC count.

pub fn count_to_physical(&self, count: f64, sensitivity: f64) -> f64

Convert raw ADC count to physical unit using sensor sensitivity.

sensitivity is in V/(m/s) for velocity sensors.

pub fn overall_sensitivity(&self, sensor_sensitivity: f64) -> f64

Compute overall sensitivity in counts per physical unit.

This is the value that goes into <InstrumentSensitivity><Value>.

Trait Implementations

impl Clone for AdcConversion

fn clone(&self) -> AdcConversion

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AdcConversion

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for AdcConversion

fn eq(&self, other: &AdcConversion) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
