ciao ragazzi sono nuovo in questo forum e ho cominciato a pasticciare con arduino.
vi spiego il mio fantastico problemino, sto facendo un piccolo programmino con degli interruttori. i quali quando mi siedo su una sedia l'arduino mi butta fuori dei valori, e fin qui tutto ok!!!
ora devo leggerli con phpd dei valori...
io uso win xp e utilizzo questo codice e uso la classe: php_serial.class.php
<?php
/* Simple serial relay script for turning my sprinkler system on and off from the web!
Utilizes the PHP Serial class by Rémy Sanchez <thenux@gmail.com> (Thanks you rule!!)
to communicate with the QK108/CK1610 serial relay board!
*/
//check the GET action var to see if an action is to be performed
if (isset($_GET['action'])) {
//Action required
//Load the serial port class
require("php_serial.class.php");
//Initialize the class
$serial = new phpSerial();
//Specify the serial port to use... in this case COM1
$serial->deviceSet("COM3");
//Set the serial port parameters. The documentation says 9600 8-N-1, so
$serial->confBaudRate(9600); //Baud rate: 9600
$serial->confParity("none"); //Parity (this is the "N" in "8-N-1")
$serial->confCharacterLength(8); //Character length (this is the "8" in "8-N-1")
$serial->confStopBits(1); //Stop bits (this is the "1" in "8-N-1")
$serial->confFlowControl("none"); //Device does not support flow control of any kind, so set it to none.
//Now we "open" the serial port so we can write to it
$serial->deviceOpen();
//Issue the appropriate command according to the serial relay board documentation
if ($_GET['action'] == "on") {
//to turn relay number 1 on, we issue the command
//$serial->sendMessage("1");
// Or to read from
print $serial->readPort();
} else if ($_GET['action'] == "off") {
//to turn relay number 1 off, we issue this command
$serial->sendMessage("0");
}
//We're done, so close the serial port again
$serial->deviceClose();
}
/*
$fp = fopen('COM3', 'r+');
if(!$fp){
echo"Port not accessible";
}else{
echo"Port COM3 opened successfully";
}
$buffer = fgets($fp);
echo"Read from buffer: $buffer";

pero' non legge nulla ... possibile che nn supporti win in lettura??
ke altre soluzioni posso adottare????
grazie a tutti in anticipo
