Library and CLI tool to connect to USB blood pressure monitors and extract measurements.

Supported devices:

• VEROVAL® duo control, thanks to Petko Bordjukov

Library Usage

Add to your Cargo.toml:

[dependencies]
usb-bpm-exporter = "0.1"

Use in your code:

use usb_bpm_exporter::{Device, Result};

fn main() -> Result<()> {
    let mut device = Device::new("/dev/ttyACM0")?;
    
    // Get measurement count for user 1
    let count = device.count(1)?;
    println!("User has {} measurements", count);
    
    // Get all observations for user 1
    let observations = device.observations(1)?;
    for obs in observations {
        if let Some(datetime) = obs.datetime() {
            println!("{}: {}/{} mmHg, pulse {}", 
                datetime, obs.systolic, obs.diastolic, obs.pulse);
        }
    }
    
    Ok(())
}

CLI Usage

guix shell rust rust-cargo gcc-toolchain pkg-config eudev
cargo build

Start with debugging enabled; where /dev/ttyACM0 is the serial port, and 1 the user:

$ sudo ./target/debug/usb-bpm-exporter /dev/ttyACM0 1
