Crate sdp8xx 

A platform agnostic Rust driver for the Sensirion SDP8xx differential pressure sensor, based on the embedded-hal traits. Heavily inspired by the sgp30 driver by Danilo Bergen

The Device

The Sensirion SDP8xx is a differential pressure sensor. It has an I2C interface.

• Datasheet
• Product Page

Usage

Instantiating

Import this crate and an embedded_hal implementation, then instantiate the device:

use linux_embedded_hal as hal;

use hal::{Delay, I2cdev};
use sdp8xx::Sdp8xx;

let dev = I2cdev::new("/dev/i2c-1").unwrap();
let address = 0x25;
let mut sdp = Sdp8xx::new(dev, address, Delay);

See sdp8xx-rpi-test for an example on the raspberry pi.

Fetching Device Information

You can fetch the product id of your sensor:

use linux_embedded_hal as hal;
use hal::{Delay, I2cdev};
use sdp8xx::ProductIdentifier;
use sdp8xx::Sdp8xx;

let dev = I2cdev::new("/dev/i2c-1").unwrap();
let mut sdp = Sdp8xx::new(dev, 0x25, Delay);
if let Ok(product_id) = sdp.read_product_id() {
    println!("{:?}", product_id);
} else {
    eprintln!("Error during reading product ID.");
}

Fetching Some Data

You can fetch the differential pressure:

use linux_embedded_hal as hal;
use hal::{Delay, I2cdev};
use sdp8xx::Sdp8xx;

let dev = I2cdev::new("/dev/i2c-1").unwrap();
let mut sdp = Sdp8xx::new(dev, 0x25, Delay);

let data = match sdp.trigger_differential_pressure_sample() {
    Ok(d) => dbg!(d),
    Err(_) => panic!(),
};
