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.
