respeaker

Rust USB control library for the Seeed ReSpeaker Mic Array v2.0 (2886:0018).

Covers:

• LED ring — same vendor protocol as pixel_ring (usb_pixel_ring_v2.py)
• DSP tuning — same vendor protocol as tuning.py (AEC/AGC/NS/DOA/VAD, …)

Example

use respeaker::ReSpeaker;

fn main() -> respeaker::Result<()> {
    let dev = ReSpeaker::open()?;
    dev.led().off()?;
    println!("DOA: {}°", dev.tuning().doa_angle()?);
    Ok(())
}
