I am trying to use PHP to read weighing machine value(i.e., weight). Whenever I run the code below, it says
Fatal error: Maximum execution time of 300 seconds exceeded
I did something wrong, I don't know where it is?
The PHP Serial class offers a readPort() function, does not return (My assumption).
My PHP code:
<html>
<body>
<h1>Works with php</h1>
<p>First Page in PHP</p>
<?php
include 'PhpSerial.php';
$serial = new phpSerial();
$serial->deviceSet("COM3");
$serial->confBaudRate(9600);
$serial->confParity("none");
$serial->confCharacterLength(8);
$serial->confStopBits(1);
$serial->confFlowControl("none");
$serial->deviceOpen();
$serial->sendMessage("s");
$read = $serial->readPort();
echo ("Weight--->".$read );
$serial->deviceClose();
?>
<p>Sent Data to server </p>
</body>
</html>
try like this:
require_once 'PhpSerial.php';
$serial=new phpSerial();
$serial->deviceSet('/dev/ttyACM2');
$serial->confBaudRate(9600);
$serial->confParity("none");
$serial->confCharacterLength(8);
$serial->confStopBits(1);
$serial->confFlowControl("none");
$serial->deviceOpen();
if($_GET['status']){
$serial->sendMessage($_GET['status']);
$read=$serial->readPort();
var_dump($read);
echo $read;
}
