Struct HC-SR04 sensor object

Implementations

impl<OUT, DELAY, COUNTER> HcSR04<OUT, DELAY, COUNTER>

where OUT: OutputPin, DELAY: DelayUs<u8>, COUNTER: TickerUs,

pub fn hc_sr04_new( pin_trigger: OUT, delay: &mut DELAY, timer: &mut COUNTER ) -> Self

Create new HC-SR04 object.

pub fn set_temperature(&mut self, temp: f32)

Set temperature of environment. Temperature value must be in Celsius unit.
This function only available if feature "temperature" or "humidity" enabled.

pub fn set_humidity(&mut self, humidity: u8)

Set relative humidity of environment.
This function only available if feature "humidity" enabled.

pub fn get_distance<T>(&mut self, unit: DistanceUnit) -> Result<T, HsError>

where T: NumCast,

Measure distance. where T is numb variants.

pub fn get_last_length_echo_time<T>(&mut self, unit: TimeUnit) -> T

where T: NumCast,

Get last lenght of time soundwave detected back by sensor. Where T is number variants.

pub fn send_ping_force(&mut self)

Send ulrasonic sundwave.

pub fn on_echo_pulse(&mut self) -> Result<(), HsError>

Update state of HC-SR04 sensor. This function must called inside external interrupt (EXTI) callback.
