Struct stm32_hal2::rtc::Rtc [−][src]
Real Time Clock peripheral
Implementations
impl Rtc
[src]
pub fn new(regs: RTC, rcc: &mut RCC, pwr: &mut PWR, config: RtcConfig) -> Self
[src]
Create and enable a new RTC abstraction, and configure its clock source and prescalers.
From AN4759, Table 7, when using the LSE (The only clock source this module
supports currently), set prediv_s
to 255, and prediv_a
to 127 to get a
calendar clock of 1Hz.
The bypass
argument is true
if you’re using an external oscillator that
doesn’t connect to OSC32_IN
, such as a MEMS resonator.
Note: You may need to run dp.RCC.apb1enr.modify(|_, w| w.pwren().set_bit());
before
constraining RCC, eg before running this constructor.
Note that if using HSE as the clock source, we assume you’ve already enabled it, eg
in clock config.
pub fn set_24h_fmt(&mut self)
[src]
Sets calendar clock to 24 hr format
pub fn set_12h_fmt(&mut self)
[src]
Sets calendar clock to 12 hr format
pub fn is_24h_fmt(&self) -> bool
[src]
Reads current hour format selection
pub fn set_wakeup(&mut self, exti: &mut EXTI, sleep_time: f32)
[src]
Setup periodic auto-wakeup interrupts. See ST AN4759, Table 11, and more broadly,
section 2.4.1. See also reference manual, section 27.5.
In addition to running this function, set up the interrupt handling function by
adding the line make_rtc_interrupt_handler!(RTC_WKUP);
somewhere in the body
of your program.
sleep_time
is in ms.
pub fn enable_wakeup(&mut self)
[src]
Enable the wakeup timer.
pub fn disable_wakeup(&mut self)
[src]
Disable the wakeup timer. // todo dry with enable.
pub fn set_wakeup_interval(&mut self, sleep_time: f32)
[src]
Change the sleep time for the auto wakeup, after it’s been set up.
Sleep time is in MS. Major DRY from set_wakeup
.
pub fn clear_wakeup_flag(&mut self)
[src]
Clears the wakeup flag. Must be cleared manually after every RTC wakeup. Alternatively, you could call this in the RTC wakeup interrupt handler.
