Installation

Install the plugin with cargo:

Alternatively add the dependency directly to Cargo.toml:

[dependencies]
tauri-plugin-hid = "0.1.1"

Install the ts/js api:

npm add @redfernelec/tauri-plugin-hid-api

Add the plugin to src-tauri/src/lib.rs, for example:

tauri::Builder::default()
    .plugin(tauri_plugin_opener::init())
    .plugin(tauri_plugin_hid::init())   // Register hid plugin
    .run(tauri::generate_context!())
    .expect("error while running tauri application");

Add permisions to src-tauri/capabilities/default.json:

"permissions": [
    "core:default",
    "opener:default",
    "hid:default"
]

Example usage in Frontend

Basic usage:

import { HidDevice, enumerate } from "@redfernelec/tauri-plugin-hid-api";

let myDevice: HidDevice | null = null;

// Enumerate devices and find one based on product string
let devices = await enumerate();
for (const device of devices) {
    if (device.productString === "My Device") {
        myDevice = device;
        break;
    }
}

if(myDevice) {
    await myDevice.open();
    await myDevice.write(new Uint8Array([0x00, 0x00]));
    let data = await myDevice.read(2);
    await myDevice.close();
}
