Struct Bme280Bus

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

BME280 bus.

Implementations

impl<SPI> Bme280Bus<SPI>

pub fn new(spi: SPI) -> 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::spi1::Bme280Bus;

let mut bme: Bme280Bus<_> = Bme280Bus::new(spi);

pub fn free(self) -> SPI

Free the SPI bus and CS pin from the BME280.

Example

use bme280_multibus::spi1::Bme280Bus;

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