 I would suggest using the full path in the line

Code: Select all

os.system('./script.sh')
So if your script.sh file is located in the /home/pi directory your line would look like this

Code: Select all

os.system('/home/pi/script.sh')
need this for it to run as service. thanks!

Re: GPIO help

Sounds like your button may be push-to-open. Try the following: import RPi.GPIO as GPIO,time,os,datetime GPIO.setmode(GPIO.BCM) GPIO.setup(24, GPIO.IN, pull_up_down = GPIO.PUD_UP) while True: i = GPIO.input(24) print(datetime.datetime.now().strftime('%H:%M:%S.%f')[:-3],i) if i == GPIO.HIGH: print('...

Re: GPIO help

Is your button push-to-close or push-to-open? Why does it have to be on Manjaro? If working correctly that code should print nothing when the button is not pressed and print 'pressed' repeatedly when the button is pressed. my set up requires manjaro so its script is telling me that: 1) GPIO works &...

 We don't know what code is being used. We don't know how the switch is connected. The question is pointless.

From the error message it looks like you changed 24 to 18. Do you understand the difference between physical pin numbers (BOARD) and BCM GPIO pin numbers. https://pinout.xyz/ changed to 24, get this output: pressed pressed pressed pressed pressed ad nauseum Is that with your button connected betwee...

 RPi.GPIO is only supported on Raspbian. You'll need to pull the source package and hack it to work on your alien operating system.
it already is maintained on manjaro

Re: GPIO help

Please edit your post and place your code in code tags. You should not need 'sudo' before 'python'. Replace your os.system with a print statement until it works. Add a photo of your wiring.

Re: GPIO help

If your pulling a GPIO input up, the input will normally be High and you need to test for Low: import RPi.GPIO as GPIO,time,os GPIO.setmode(GPIO.BCM) GPIO.setup(24, GPIO.IN, pull_up_down = GPIO.PUD_UP) while True: if GPIO.input(24) == GPIO.LOW: print('pressed') time.sleep(0.05) This tests fine for ...
