Struct MicGain 

pub struct MicGain(/* private fields */);

Analog microphone pre-amplifier gain, 0–30 dB in 3 dB steps. The codec adds a further +24 dB digital ADC_SCALE (register 0x16 reset value).

Implementations

impl MicGain

pub const DB0: Self

0 dB (M5Unified’s default).

pub const DB30: Self

Maximum, 30 dB.

pub const fn from_db(db: u8) -> Self

The nearest step at or below db, clamped to 0–30 dB.

pub const fn db(self) -> u8

The gain in dB.

Trait Implementations

impl Clone for MicGain

fn clone(&self) -> MicGain

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MicGain

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

Formats the value using the given formatter.

impl Format for MicGain

fn format(&self, f: Formatter<'_>)

Writes the defmt representation of self to fmt.

impl PartialEq for MicGain

fn eq(&self, other: &MicGain) -> 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.
