HLK-TX510-SDK

This is a TypeScript library for interacting with the HLK-TX510 device. It provides a simple interface for sending commands to the device and handling responses.

Installation

You can install the library using npm or yarn:

npm install hlk-tx510-sdk

or

yarn add hlk-tx510-sdk

Usage

First, import the HLKTX510SDK class from the library:

import { HLKTX510SDK } from 'hlk-tx510-sdk';

Then, create a new instance of the HLKTX510SDK class, passing the port path to the constructor:

const sdk = new HLKTX510SDK('/dev/tty-usbserial1');

The HLKTX510SDK class extends EventEmitter, so you can listen for events emitted by the class:

sdk.on('recognition', (message) => {
  console.log('Recognition message received:', message);
});

sdk.on('registration', (message) => {
  console.log('Registration message received:', message);
});

sdk.on('user-deletion', (message) => {
  console.log('User deletion message received:', message);
});

sdk.on('user-list', (message) => {
  console.log('User list message received:', message);
});

sdk.on('unknown-message', (message) => {
  console.log('Unknown message received:', message);
});

sdk.on('error', (err) => {
  console.error('Error occurred:', err);
});

You can send commands to the device using the following methods:

• recognizeFace(): Recognizes a face.
• registerFace(): Registers a face.
• turnOffBacklight(): Turns off the backlight.
• turnOnBacklight(): Turns on the backlight.
• turnOffDisplay(): Turns off the display.
• turnOnDisplay(): Turns on the display.
• deleteUser(userId: number): Deletes a user by their ID.
• sendUserListCommand(): Sends a command to get the list of users.

For example, to recognize a face:

sdk.recognizeFace();

To delete a user:

sdk.deleteUser(1234);
