Struct rustduino::sensors::AHT10

#[repr(C, packed)]
pub struct AHT10<'a> { /* fields omitted */ }

Used to control the AHT10 Arduino sensor

Elements

• address - a u8, used to store the address to control the functioning AHT10 sensor.
• i2c - a twi struct object, which would be used to interface the functioning of sensor with communication protocol I2C.
• vec - a vector with u8 objects, It would be used to store the data read through the sensors.

Implementations

impl<'a> AHT10<'a>

pub fn new(&mut self) -> &'static mut Self

Creates a new memory mapped IO at the correct location including a 20ms reset delay for wake-up.

Returns

• a reference to AHT10 structure - Which would be used to control the sensor.

pub fn get() -> &'static mut Self

Returns reference to the structure without any reset delay.

Returns

• a reference to AHT10 structure - Which would be used to control the sensor.

pub unsafe fn initialise(&mut self) -> bool

Initiates the transmission by self initiating the sensor.

Returns

• a boolean - Which is true if transmission initiated otherwise false.

pub fn soft_reset(&mut self)

Restart sensor, without power off in around ~20ms with all registers restored to default.

pub unsafe fn read_to_buffer(&mut self)

Reads data from slave mode using the I2C protocol.

pub unsafe fn trigger_slave(&mut self)

Triggers the AHT10 to read temperature/humidity.

pub unsafe fn wait_for_idle(&mut self)

Adds a delay of 5ms when the sensor is already busy with some processing.

pub unsafe fn perform_measurement(&mut self)

Performs measurement of temperature using the functions trigger_slave() and read_to_buffer().

pub unsafe fn status(&mut self) -> u8

Reads value returned by the slave.

Returns

• a u8 - The read value.

pub fn relative_humidity(&mut self) -> f64

Reads 20 bit raw humidity data.

Returns

• a f64 - The relative humidity in percentage.

pub fn temperature(&mut self) -> f64

Reads 20 bit raw temperature data.

Returns

• a f64 - The temperature in degree celsius.
