Clock prescaler for PWM

The prescaler dictates the PWM frequency, together with the IO clock. The formula is as follows:

F_pwm = CLK_io / (Prescaler * 256);

Prescaler	16 MHz Clock	8 MHz Clock
Direct	62.5 kHz	31.3 kHz
Prescale8	7.81 kHz	3.91 kHz
Prescale64	977 Hz	488 Hz
Prescale256	244 Hz	122 Hz
Prescale1024	61.0 Hz	30.5 Hz

Variants

Direct

No prescaling, the IO clock drives the timer directly.

Prescale8

Divide the IO clock by 8.

Prescale64

Divide the IO clock by 64.

Prescale256

Divide the IO clock by 256.

Prescale1024

Divide the IO clock by 1024.

Trait Implementations

impl Clone for Prescaler

fn clone(&self) -> Prescaler

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Prescaler

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

Formats the value using the given formatter.

impl Ord for Prescaler

fn cmp(&self, other: &Prescaler) -> Ordering

This method returns an [Ordering] between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Prescaler

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

impl PartialOrd for Prescaler

fn partial_cmp(&self, other: &Prescaler) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
