Control Beaglebone GPIO pin from web page.

[sayalik...@gmail.com]

Hello.

     I want to control GPIO pin of beaglebone from web page.

My ledon python code here..

import Adafruit_BBIO.GPIO as GPIO

from time import sleep

outPin="P9_12"

GPIO.setup(outPin,GPIO.OUT)

while True:

     GPIO.output(outPin, GPIO.HIGH)

     print('LED ON')

Here is my php code..

<?php

$result = 'nothing';

if (isset($_POST['set_off']))

{

 $result = 'turned off';

 shell_exec("sudo python /var/www/html/ledoff.py");

}

if (isset($_POST['set_on']))

{

 $result = 'turned on';

 shell_exec("sudo python /var/www/html/ledon.py");

}

?>

 <?php if (isset($result)) { ?>

 <h1> Action: <?php echo $result ?></h1>

 <?php } ?>

 <form action="" method="post">

 <p><input type="hidden" name="set_on" value="yes"/><input type="submit" value="LED On"/></p></form>

 <form action="" method="post">

 <p><input type="hidden" name="set_off" value="yes"/><input type="submit" value="LED Off"/></p></form>

</body>

</html>

I run code on web with 192.168.7.2:8080/gpio.php. But the LED doesn't turn to high or low.
