Source
Expand description

Wrapper for Linux GPIB.

Documentation for the functions comes from Linux GPIB Reference.

§Requirements

This crate needs to link to an installed linux-gpib user library. It will look for gpib/ib.h in either /usr/include or /usr/local/include, and for libgpib.so in either /usr/lib or /usr/local/lib.

§Example

Add dependencies below to Cargo.toml

linux-gpib-rs = { version = "0.2", features = ["async-tokio"] }

Codes below will connect to the instrument on GPIB0::1::INSTR and print out its *IDN? response.

Synchronous example with Multidevice API

use linux_gpib_rs::instrument::Board;
use linux_gpib_rs::types::IbSendEOI;
use std::error::Error;

fn main() -> Result<(), Box<dyn Error>> {
    let board = Board::with_board_number(0);
    let instruments = board.find_listeners()?;
    board.send_list(&instruments, b"*IDN?\n", IbSendEOI::default())?;
    for instr in instruments {
        let iden = instr.receive()?;
        println!("{:>20} {}", instr.visa_string(), iden.trim());
    }
    Ok(())
}

Asynchronous example

Same thing with asynchronous API.

use linux_gpib_rs::instrument::{Parameters, Board};
use linux_gpib_rs::error::GpibError;
use tokio::task::JoinSet;
use std::error::Error;

#[tokio::main]
async fn main() -> Result<(), Box<dyn Error>> {
    let board = Board::with_board_number(0);
    let instruments = board.find_listeners()?;
    let mut set = JoinSet::<Result<(String, String), GpibError>>::new();
    for instr in instruments {
        let handle = instr.open(Parameters::default())?;
        let visa_string = instr.visa_string();
        set.spawn(async move {
            let iden = handle.query("*IDN?\n").await?;
            Ok((visa_string, iden))
        });
    }
    while let Some(Ok(val)) = set.join_next().await {
        if let Ok((visa_string, iden)) = val {
            println!("{:>20} {}", visa_string, iden.trim());
        }
    }
    Ok(())
}
