Struct RtcioWakeupSource

pub struct RtcioWakeupSource<'a, 'b> { /* private fields */ }

Available on crate feature unstable only.

RTC_IO wakeup source

RTC_IO wakeup allows configuring any combination of RTC_IO pins with arbitrary wakeup levels to wake up the chip from sleep. This wakeup source can be used to wake up from both light and deep sleep.

let mut rtc = Rtc::new(peripherals.LPWR);

let reason = reset_reason(Cpu::ProCpu);
let wake_reason = wakeup_cause();

println!("{:?} {?}", reason, wake_reason);

let delay = Delay::new();
let timer = TimerWakeupSource::new(Duration::from_secs(10));
let mut pin_0 = peripherals.GPIO2;
let mut pin_1 = peripherals.GPIO3;
let wakeup_pins: &mut [(&mut dyn gpio::RtcPinWithResistors, WakeupLevel)] = &mut [
    (&mut pin_0, WakeupLevel::Low),
    (&mut pin_1, WakeupLevel::High),
];

let rtcio = RtcioWakeupSource::new(wakeup_pins);
delay.delay_millis(100);
rtc.sleep_deep(&[&timer, &rtcio]);

Implementations
