[Python 3.X] Exécution Programme PYTHON sur une page PHP

Bonjour, j’ai un petit problème de récupération sur une page PHP de ce script python qui permet d’acquérir des valeurs d’un CAN sur une raspberry pi :

import quick2wire.i2c as i2c

adc_address1 = 0x68

adc_channel1 = 0x98
adc_channel2 = 0xB8

adc_channel4 = 0xF8
 
 
for line in open('/proc/cpuinfo').readlines():
    m = re.match('(.*?)\s*:\s*(.*)', line)
    if m:
        (name, value) = (m.group(1), m.group(2))
        if name == "Revision":
            if value [-4:] in ('0002', '0003'):
                i2c_bus = 0
            else:
                i2c_bus = 1
            break
 
with i2c.I2CMaster(i2c_bus) as bus:
 
    def getadcreading(address, channel):
        bus.transaction(i2c.writing_bytes(address, channel))
        time.sleep(0.05)
        h, l, r = bus.transaction(i2c.reading(address,3))[0]
        time.sleep(0.05)
        h, l, r = bus.transaction(i2c.reading(address,3))[0]
 
        t = (h << 8) | l
        v = t * 0.000154
        if v < 5.5:
            return v
        else:
            return 0.00
 
    while True:
 
        print("1: %f" % getadcreading(adc_address1, adc_channel1))
        print("2: %f" % getadcreading(adc_address1, adc_channel2))
        print("3: %f" % getadcreading(adc_address1, adc_channel3))
        print("4: %f" % getadcreading(adc_address1, adc_channel4))
        print("5: %f" % getadcreading(adc_address2, adc_channel1))
        print("6: %f" % getadcreading(adc_address2, adc_channel2))
        print("7: %f" % getadcreading(adc_address2, adc_channel3))
        print("8: %f" % getadcreading(adc_address2, adc_channel4))
        break

Ce script fonctionne quand on le lance depuis le terminal mais depuis une page PHP rien ne s’affiche.

J’utilise la fonction en PHP:

Code:

$output6 = passthru("sudo python adc_1.py", $output61);
            echo var_dump($output6)."test6<br>";
            echo var_dump($output61)."test6";
            echo "<br>test6 fait<br>";
