Connect to serial port with PHP

Inspired by PHP-Serial, I simplify it and include composer.json to install via composer.

Actually, it works on linux. This library is suitable for working with Arduino.

composer require "lepiaf/serialport"

You can check a full example in example folder. It contains a basic Arduino sketch and php file to read it.

Instantiate a new SerialPort object with a parser and configure tty.

<?php

use lepiaf\SerialPort\SerialPort;
use lepiaf\SerialPort\Parser\SeparatorParser;
use lepiaf\SerialPort\Configure\TTYConfigure;

$serialPort = new SerialPort(new SeparatorParser(), new TTYConfigure());

$serialPort->open("/dev/ttyACM0");
while ($data = $serialPort->read()) {
    echo $data."\n";

    if ($data === "OK") {
        $serialPort->write("1\n");
        $serialPort->close();
    }
}

For mac os, you must use TTYMacConfigure. It will use stty -f instead of stty -F.
