Home Linux project?

How would you do this?

 

I need to take an input from a Gpio pin on a pi and then send an output to another GPIO pin. I have tried using openhapian and I can’t see how you link GPIO output up. Would I better using python under a standard OS?

 

Thanks

You are talking about openHABian, an OS image for the Raspberry Pi available at:

 

https://www.openhab.org/

 

Sorry, I'm not familier with openHABian at all. By the looks of things, it provides a web-based interface for you to use from a separate device. I'm guessing that interface includes some way for you to place executable code of some sort on the device, does that sound right?

 

If you were doing this on Raspian, you would connect to the Raspberry Pi, start up a command line interface, make sure you had the Python GPIO libraries installed and start writing code to read / write values to pins. I'm guessing openHABian might well include Python somewhere, it's probably just a case of figuring out how to add and then run scripts.

Oh, I see:

 

https://www.openhab.org/docs/installation/openhabian.html

 

openHABian installs on top of Debian / Raspbian, so you can still log in to your Raspberry Pi via SSH or by connecting up a screen and keyboard and start writing whatever Python code you want. I'm guessing you might be aiming to integrate with some existing feature, though, yes?

In python something like:

from gpiozero import Button
from signal import pause

def activateOutput():
   output.on()

def deactivateOutput():
   output.off()

input = Button(17, pull_up=False))
output = DigitalOutputDevice(18,active_high=True)

input.when_pressed = activateOutput
intput.when_released = deactivateOutput

print("Ready")
pause()
