Trait shtcx::LowPower

pub trait LowPower<E: Error> {
    const WAKEUP_TIME_US: u32;

    // Required methods
    fn sleep(&mut self) -> Result<(), Error<E>>;
    fn start_wakeup(&mut self) -> Result<(), Error<E>>;
    fn wakeup(&mut self, delay: &mut impl DelayNs) -> Result<(), Error<E>>;
}

Low power functionality (sleep and wakeup).

This functionality is only present on some of the sensors (e.g. the SHTC3, but not the SHTC1).

Required Associated Constants

const WAKEUP_TIME_US: u32

Time the sensor needs until it is ready after a wakeup call.

Required Methods

fn sleep(&mut self) -> Result<(), Error<E>>

Set sensor to sleep mode.

When in sleep mode, the sensor consumes around 0.3-0.6 µA. It requires a dedicated wakeup command to enable further I2C communication.

fn start_wakeup(&mut self) -> Result<(), Error<E>>

Wake up sensor from sleep mode.

fn wakeup(&mut self, delay: &mut impl DelayNs) -> Result<(), Error<E>>

Wake up sensor from sleep mode and wait until it is ready.

Object Safety

This trait is not object safe.
