[−][src]Struct stm32l0xx_hal::lptim::LpTimer
Low-Power Timer (LPTIM).
The Low-Power Timer is a 16-bit timer with a prescaler of up to 128. It can run off of the APB1, LSI, HSI16, or LSE clocks. With LSE, the slowest clock at 32.768 kHz, this results in a maximum timeout of 256 seconds, or 4 minutes and 16 seconds.
The timer can be initialized either in one-shot mode or in periodic mode, using init_oneshot
or init_periodic respectively. In periodic mode, the embedded-hal Periodic marker trait is
implemented and the CountDown implementation uses Hertz as the time unit. In one-shot mode,
the CountDown implementation instead uses MicroSeconds, allowing for a multi-second timeout
to be configured (with the tradeoff being a larger code size due to use of 64-bit arithmetic).
Methods
impl LpTimer<Periodic>[src]
pub fn init_periodic(
lptim: LPTIM,
pwr: &mut PWR,
rcc: &mut Rcc,
clk: ClockSrc
) -> Self[src]
lptim: LPTIM,
pwr: &mut PWR,
rcc: &mut Rcc,
clk: ClockSrc
) -> Self
Initializes the Low-Power Timer in periodic mode.
The timer needs to be started by calling .start(freq).
impl LpTimer<OneShot>[src]
pub fn init_oneshot(
lptim: LPTIM,
pwr: &mut PWR,
rcc: &mut Rcc,
clk: ClockSrc
) -> Self[src]
lptim: LPTIM,
pwr: &mut PWR,
rcc: &mut Rcc,
clk: ClockSrc
) -> Self
Initializes the Low-Power Timer in one-shot mode.
The timer needs to be started by calling .start(freq).
impl<M: CountMode> LpTimer<M>[src]
pub fn free(self) -> LPTIM[src]
Disables and destructs the timer, returning the raw LPTIM peripheral.
pub fn enable_interrupts(&mut self, interrupts: Interrupts)[src]
Disables the timer and enables the given interrupts.
pub fn disable_interrupts(&mut self, interrupts: Interrupts)[src]
Disables the timer and disables the given interrupts.
