Enum esp32c3_hal::adc::Attenuation

pub enum Attenuation {
    Attenuation0dB,
    Attenuation2p5dB,
    Attenuation6dB,
    Attenuation11dB,
}

The attenuation of the ADC pin

Variants

Attenuation0dB

0 dB attenuation, measurement range: 0 - 800 mV

Attenuation2p5dB

2.5 dB attenuation, measurement range: 0 - 1100 mV

Attenuation6dB

6 dB attenuation, measurement range: 0 - 1350 mV

Attenuation11dB

11 dB attenuation, measurement range: 0 - 2600 mV

Implementations

impl Attenuation

pub const ALL: &'static [Attenuation] = &[Attenuation::Attenuation0dB, Attenuation::Attenuation2p5dB, Attenuation::Attenuation6dB, Attenuation::Attenuation11dB]

List of all supported attenuations

pub const fn ref_mv(&self) -> u16

Reference voltage in millivolts

Vref = 10 ^ (Att / 20) * Vref0 where Vref0 = 1.1 V, Att - attenuation in dB

To colvert raw value to millivolts use folmula: V = D * Vref / 2 ^ R where D - raw ADC value, R - resolution in bits

Trait Implementations

impl Clone for Attenuation

fn clone(&self) -> Attenuation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq<Attenuation> for Attenuation

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

This method tests for self and other values to be equal, and is used by ==.

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

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