Struct hrs3300::Hrs3300

pub struct Hrs3300<I2C> { /* fields omitted */ }

HRS3300 device driver

Methods

impl<I2C> Hrs3300<I2C>

pub fn new(i2c: I2C) -> Self

Create new instance of the HRS3300 device.

pub fn destroy(self) -> I2C

Destroy driver instance, return I²C bus instance.

impl<I2C, E> Hrs3300<I2C> where
    I2C: Write<Error = E> + WriteRead<Error = E>, 

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

Initialize the status of registers

A custom initialization can also be achieved using write_register() directly.

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

Enable the heart-rate sensor (HRS).

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

Disable the heart-rate sensor (HRS).

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

Enable the oscillator.

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

Enable the oscillator.

pub fn set_conversion_delay(
    &mut self,
    delay: ConversionDelay
) -> Result<(), Error<E>>

Set the HRS conversion delay (waiting time between conversion cycles)

pub fn set_gain(&mut self, gain: Gain) -> Result<(), Error<E>>

Set the HRS ADC gain

pub fn set_als_resolution(
    &mut self,
    resolution: AlsResolution
) -> Result<(), Error<E>>

Set the ambient light sensor ADC resolution

pub fn set_led_current(&mut self, current: LedCurrent) -> Result<(), Error<E>>

Set the LED driver current

pub fn device_id(&mut self) -> Result<u8, Error<E>>

Read the device ID (0x21).

pub fn read_hrs(&mut self) -> Result<u32, Error<E>>

Read heart rate sensor measurement (CH0)

pub fn read_als(&mut self) -> Result<u32, Error<E>>

Read ambient light sensor measurement (CH1)

pub fn write_register(
    &mut self,
    register: u8,
    value: u8
) -> Result<(), Error<E>>

Custom register write.

This can be used to do a custom initialization, for example.

pub fn read_register(&mut self, register: u8) -> Result<u8, Error<E>>

Custom register read.
