hardware driver for ST LPS28DFW pressure sensor

This is a platform agnostic Rust driver for the LPS28DFW pressure sensor from ST, based on the embedded-hal traits.

This driver allows you to:

• read pressure and temperature values from sensor
• enable pressure value interrupts
• set sampling rates

The device

LPS28DFW is a high precision MEMS pressure and temperature sensor for multiple fluids. Pressure measuring range is variable between 1024 and 4096 kPa.

Datasheet: LPS28DFW

Usage

To use this driver, import this crate and an embedded_hal implementation, then instantiate the device.

use ds1307::{DateTimeAccess, Ds1307, NaiveDate};
use linux_embedded_hal::I2cdev;

fn main() {
    let dev = I2cdev::new("/dev/i2c-1").unwrap();
    let mut pressure_sensor = LPS28DFW::new(dev);
    let mut pressure_sensor_cfg = LPS28DFW::get_default_config();
    pressure_sensor.write_config(pressure_sensor_cfg).unwrap();
    let pressure = pressure_sensor.get_pressure().unwrap();
    println!("{pressure} kPa");
}

Todos

• fifo control and status methods
• temperature sensor methods
• pressure data output methods
• oneshot mode
• autoresets
• update tests
• create raspberry pi example for i2c testing

Minimum Supported Rust Version (MSRV)
