@serialport/parser-delimiter

What is @serialport/parser-delimiter?

@serialport/parser-delimiter is a parser for the serialport library that allows you to split data into chunks based on a specified delimiter. This is particularly useful for processing data streams where messages are separated by a specific character or sequence of characters.

What are @serialport/parser-delimiter's main functionalities?

Basic Usage

This code demonstrates how to set up a basic serial port connection and use the delimiter parser to split incoming data based on newline characters.

const SerialPort = require('serialport');
const Delimiter = require('@serialport/parser-delimiter');

const port = new SerialPort('/dev/tty-usbserial1');
const parser = port.pipe(new Delimiter({ delimiter: '\n' }));

parser.on('data', data => {
  console.log('Received data:', data.toString());
});

Custom Delimiter

This example shows how to use a custom delimiter (in this case, a carriage return followed by a line feed) to split incoming data.

const SerialPort = require('serialport');
const Delimiter = require('@serialport/parser-delimiter');

const port = new SerialPort('/dev/tty-usbserial1');
const parser = port.pipe(new Delimiter({ delimiter: Buffer.from([0x0D, 0x0A]) })); // Carriage return and line feed

parser.on('data', data => {
  console.log('Received data:', data.toString());
});

Handling Binary Data

This example demonstrates how to handle binary data streams by using a custom binary delimiter.

const SerialPort = require('serialport');
const Delimiter = require('@serialport/parser-delimiter');

const port = new SerialPort('/dev/tty-usbserial1');
const parser = port.pipe(new Delimiter({ delimiter: Buffer.from([0xFF]) })); // Custom binary delimiter

parser.on('data', data => {
  console.log('Received binary data:', data);
});
