I've made a python script using the RPi.GPIO library. I need to run it without root but I get this error when running it with "python ./script.py":
No access to /dev/mem. Try running as root!
I've read in many places that you no longer need root with the latest version of the library but I still get the error after updating. The version I have is RPi.GPIO 0.56.110a3
With sudo everythingHere is the code:
import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BCM)
GPIO.setwarnings(False)
GPIO.setup(18,GPIO.OUT)
print "LED on"
GPIO.output(18,GPIO.HIGH)
time.sleep(1)
print "LED off"
GPIO.output(18,GPIO.LOW)
And the full error:
pi@raspberrypi ~/Desktop/python $ python ./sensors.py
Traceback (most recent call last):
File "./sensors.py", line 5, in <module>
GPIO.setup(18,GPIO.OUT)
RuntimeError: No access to /dev/mem. Try running as root!
When I run it as root it works correctly.
