Implementations§

Source§

impl<D, I> MCP9808Async<D, I2cDeviceAsync<I, SevenBitAddress>>
where I: I2c<SevenBitAddress> + ErrorType, D: DelayNs,

Source

pub fn new_i2c(delay: D, interface: I, address: Address) -> Self

Initializes a new device with the given address on the specified bus. This consumes the I2C bus I.

Before using this device, you should call the Self::init method which initializes the device and ensures that it is working correctly.

Source§

impl<D: DelayNs, I: RegisterInterfaceAsync> MCP9808Async<D, I>

Source

pub async fn init(&mut self) -> Result<(), InitError<I::BusError>>

Initializes the sensor by verifying its device id and manufacturer id. Not mandatory, but recommended.

Source

pub async fn read_register<R>( &mut self, ) -> Result<R, TransportError<<R as Register>::CodecError, I::BusError>>
where R: ReadableRegister + MCP9808Register,

Reads from the given register. For a list of all available registers, refer to implementors of MCP9808Register.
