ciao ragazzi sto sperimentando un po' di roba con arduino e php ma sto impazzendo...
sto usando la classe php_serial.class.php
per leggere la porta seriale
e faccio stampare da arduino un valore 0..
il problema è che nn stampa proprio nulla!!!
questo è il codice
Codice 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
$ardu = $serial->readPort();
if($ardu == NULL)
print "vuoto";
else
print "pieno";
} 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();
}

codice arduino
cosa sbaglio^^??Codice PHP:int sens1,sens2,sens3,sens4;
int pinSens1,pinSens2,pinSens3,pinSens4;
int incomingByte; // for incoming serial data
void setup() {
sens1=0;
sens2=0;
sens3=0;
sens4=0;
pinSens1=3;
pinSens2=5;
pinSens3=9;
pinSens4=11;
pinMode(pinSens1, INPUT);
pinMode(pinSens2, INPUT);
pinMode(pinSens3, INPUT);
pinMode(pinSens4, INPUT);
incomingByte = 0;
Serial.begin(9600);
}
void loop() {
sens1=digitalRead(pinSens1);
sens2=digitalRead(pinSens2);
sens3=digitalRead(pinSens3);
sens4=digitalRead(pinSens4);
outSens(sens1, sens2, sens3, sens4);
if (Serial.available() > 0) {
// read the incoming byte:
incomingByte = Serial.read();
// say what you got:
Serial.write("ricevuto");
}
delay(100);
}
void outSens(int s1,int s2,int s3,int s4){
if(s1==0&&s2==0&&s3==0&&s4==0){
//seduto dx solo culo
Serial.println("0");
}
else if(s1==0&&s2>0&&s3==0&&s4==0){
//seduto dx solo culo
Serial.write("1");
}
else if(s1==0&&s2>0&&s3>0&&s4==0){
//seduto dx culo+schiena
Serial.write("2");
}
else if(s1==0&&s2>0&&s3>0&&s4>0){
//seduto dx culo+schiena+gambe
Serial.write("3");
}
else if(s1>0&&s2==0&&s3==0&&s4==0){
//seduto sx
Serial.write("4");
}
else if(s1>0&&s2>0&&s3==0&&s4==0){
//seduto sx+dx solo culo
Serial.write("5");
}
else if(s1>0&&s2>0&&s3>0&&s4==0){
//seduto sx+dx culo+schiena
Serial.write("6");
}
else if(s1>0&&s2>0&&s3>0&&s4>0){
//seduto sx+dx culo+schiena+gambe
Serial.write("7");
}
}
xke da php con print $serial->readPort(); non stampa nulla???
aiuto
