autd3-rs

Async client library for AUTD3, an airborne ultrasound tactile display that produces midair haptic sensations without the user wearing any device.

This crate drives AUTD3 devices over EtherCAT: it owns the realtime bus thread, builds the wire frames, and exposes an async API for sending emission patterns and amplitude modulation.

Usage

autd3-rs provides the client; the transport, the emission patterns, and the modulation waveforms live in companion crates.

[dependencies]
autd3-rs = "0.7.0"
autd3-rs-link-echocat = "0.7.0"
autd3-rs-pattern = "0.7.0"
autd3-rs-modulation = "0.7.0"
