Methods
impl SYST[src]
pub fn is_counter_enabled(&self) -> bool[src][−]
Checks if counter is enabled
pub fn enable_counter(&self)[src][−]
Enables counter
pub fn disable_counter(&self)[src][−]
Disables counter
pub fn is_interrupt_enabled(&self) -> bool[src][−]
Checks if SysTick interrupt is enabled
pub fn enable_interrupt(&self)[src][−]
Enables SysTick interrupt
pub fn disable_interrupt(&self)[src][−]
Disables SysTick interrupt
pub fn get_clock_source(&self) -> SystClkSource[src][−]
Gets clock source
pub fn set_clock_source(&self, clk_source: SystClkSource)[src][−]
Sets clock source
pub fn has_wrapped(&self) -> bool[src][−]
Checks if the counter wrapped (underflowed) since the last check
pub fn get_reload(&self) -> u32[src][−]
Gets reload value
pub fn set_reload(&self, value: u32)[src][−]
Sets reload value
Valid values are between 1 and 0x00ffffff.
pub fn get_current(&self) -> u32[src][−]
Gets current value
pub fn clear_current(&self)[src][−]
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[src][−]
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[src][−]
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[src][−]
Checks if an external reference clock is available
