Rust BME280 Crate

A Rust crate to query temperature, pressure and humidity from sensor BME280

https://gitlab.com/claudiomattera/bme280-rs/

Usage

Add the dependency to Cargo.toml.

[dependencies.bme280-rs]
version = "0.1.0"

A Bme280 structure can be created from an I²C interface and a delay function. The initial sampling configuration disables all measurements, so it is necessary to reconfigure the chip with the desired settings before read samples.

use bme280_rs::{Bme280, Configuration, Oversampling, SensorMode};

let i2c = ...
let delay = ...

let mut bme280 = Bme280::new(i2c, delay);

bme280.init()?;

bme280.set_sampling_configuration(
    Configuration::default()
        .with_temperature_oversampling(Oversampling::Oversample1)
        .with_pressure_oversampling(Oversampling::Oversample1)
        .with_humidity_oversampling(Oversampling::Oversample1)
        .with_sensor_mode(SensorMode::Normal)
)?;

if let Some(temperature) = bme280.read_temperature()? {
    println!("Temperature: {} C", temperature);
} else {
    println!("Temperature reading was disabled");
}
