Struct ClockTree 

pub struct ClockTree {
    pub sys_clk_hz: u32,
    pub ref_clk_hz: u32,
    pub peri_clk_hz: u32,
}

Derived clock tree frequencies. Recomputed eagerly whenever any clock-relevant register (CLOCKS, PLL_SYS, PLL_USB) changes.

Fields

sys_clk_hz: u32

Effective system clock in Hz. Drives the Pacer.

ref_clk_hz: u32

Effective reference clock in Hz.

peri_clk_hz: u32

Effective peripheral clock in Hz (UART / SPI / I2C source). Follows the selected CLK_PERI_CTRL.AUXSRC on RP2040; falls back to sys_clk_hz when the peripheral clock is not separately programmed (the pico-sdk default).

Implementations

impl ClockTree

pub fn peri_hz(&self) -> u64

Current peripheral-clock frequency in Hz. UART baud-rate divisors, SPI bit-rate prescalers, and I2C SCL generators all derive their cadence from this frequency.

Trait Implementations

impl Clone for ClockTree

fn clone(&self) -> ClockTree

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ClockTree

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

Formats the value using the given formatter.

impl Default for ClockTree

fn default() -> Self

Returns the “default value” for a type.
