This crate provides a high level API for accessing and configuring a MiniDSP device.
To get started, start by instantiating the right transport. If the device is locally
connected via USB, use [transport::hid::HidTransport]. If using the WI-DG or connecting to
an instance of this program running the server component, see [transport::net::StreamTransport].
use anyhow::Result;
use futures::StreamExt;
use minidsp::{
transport::{hid, Multiplexer},
Builder, Channel, Gain, MiniDSP,
};
#[tokio::main]
async fn main() -> Result<()> {
// Get a list of local devices
let mut builder = Builder::new();
builder.with_default_usb().unwrap();
let mut devices: Vec<_> = builder
// Probe each candidate device for its hardware id and serial number
.probe()
// Filter the list to keep the working devices
.filter_map(|x| async move { x.ok() })
.collect()
.await;
// Use the first device for further commands
let dsp = devices
.first()
.expect("no devices found")
.to_minidsp()
.expect("unable to open device");
let status = dsp.get_master_status().await?;
println!("Master volume: {:.1}", status.volume.unwrap().0);
// Activate a different configuration
dsp.set_config(2).await?;
// Set the input gain for both input channels
for i in 0..2 {
dsp.input(i)?.set_gain(Gain(-10.)).await?;
}
// Mute the last output channel
dsp.output(3)?.set_mute(true).await?;
Ok(())
