Struct Bme280Bus

pub struct Bme280Bus<SPI, CS> { /* private fields */ }

BME280 bus.

Implementations

impl<SPI, CS, SpiError, PinError> Bme280Bus<SPI, CS>

where SPI: Transfer<u8, Error = SpiError> + Write<u8, Error = SpiError>, CS: OutputPin<Error = PinError>,

pub fn new(bus: SPI, cs: CS) -> Self

Creates a new Bme280Bus from a SPI peripheral and a chip select digital I/O pin.

Safety

The chip select pin must be high before being passed to this function.

Example

use bme280_multibus::spi0::Bme280Bus;
use eh0::digital::v2::OutputPin;

pin.set_high()?;
let mut bme: Bme280Bus<_, _> = Bme280Bus::new(spi, pin);

pub fn free(self) -> (SPI, CS)

Free the SPI bus and CS pin from the BME280.

Example

use bme280_multibus::spi0::Bme280Bus;
use eh0::digital::v2::OutputPin;

pin.set_high()?;
let mut bme: Bme280Bus<_, _> = Bme280Bus::new(spi, pin);
let (mut spi, mut pin) = bme.free();
