```rust use linuxembeddedhal as hal;
use linuxembeddedhal::{Delay, I2cdev}; use bme280::i2c::BME280;
// using Linux I2C Bus #1 in this example let i2cbus = I2cdev::new("/dev/i2c-1").unwrap(); let mut delay = /* ..delay provider */ // initialize the BME280 using the primary I2C address 0x76 let mut bme280 = BME280::newprimary(i2c_bus);
// or, initialize the BME280 using the secondary I2C address 0x77 // let mut bme280 = BME280::newsecondary(i2cbus);
// or, initialize the BME280 using a custom I2C address // let bme280i2caddr = 0x88; // let mut bme280 = BME280::new(i2cbus, bme280i2c_addr);
// initialize the sensor bme280.init(&mut delay).unwrap();
// measure temperature, pressure, and humidity let measurements = bme280.measure(&mut delay).unwrap();
println!("Relative Humidity = {}%", measurements.humidity); println!("Temperature = {} deg C", measurements.temperature); println!("Pressure = {} pascals", measurements.pressure); ```
To enable optional serde serialization support for the measurements struct, simply enable the serde feature, like so in Cargo.toml:
toml
[dependencies]
bme280 = { version = "0.2", features = ["serde"] }
