Methods

impl SYST

pub fn is_counter_enabled(&self) -> bool

Checks if counter is enabled

pub fn enable_counter(&self)

Enables counter

pub fn disable_counter(&self)

Disables counter

pub fn is_interrupt_enabled(&self) -> bool

Checks if SysTick interrupt is enabled

pub fn enable_interrupt(&self)

Enables SysTick interrupt

pub fn disable_interrupt(&self)

Disables SysTick interrupt

pub fn get_clock_source(&self) -> SystClkSource

Gets clock source

pub fn set_clock_source(&self, clk_source: SystClkSource)

Sets clock source

pub fn has_wrapped(&self) -> bool

Checks if the counter wrapped (underflowed) since the last check

pub fn get_reload(&self) -> u32

Gets reload value

pub fn set_reload(&self, value: u32)

Sets reload value

Valid values are between 1 and 0x00ffffff.

pub fn get_current(&self) -> u32

Gets current value

pub fn clear_current(&self)

Clears current value to 0

After calling clear_current(), the next call to has_wrapped() will return false.

pub fn get_ticks_per_10ms(&self) -> u32

Returns the reload value with which the counter would wrap once per 10 ms

Returns 0 if the value is not known (e.g. because the clock can change dynamically).

pub fn is_precise(&self) -> bool

Checks if the calibration value is precise

Returns false if using the reload value returned by get_ticks_per_10ms() may result in a period significantly deviating from 10 ms.

pub fn has_reference_clock(&self) -> bool

Checks if an external reference clock is available
