Control GPIO pins On raspberry pi 5

mik_the_mann · July 27, 2024 at 9:48 PM

I am trying to set a gpio pin to true while my system is running. The porpuse is that I have an external controller that boots is when my tv is turned on but I need to know if the pi is allready on because otherwise it will do a shutdown.

I have installed the add on raspberry pi tools but I cant get the gpio to work.

I have the script.

Python

import sys
sys.path.append('/storage/.kodi/addons/virtual.rpi-tools/lib')
from gpiozero import LED
led = LED(17)
led.on()

This produces the error

Code

Traceback (most recent call last):
  File "/storage/.kodi/addons/virtual.rpi-tools/lib/gpiozero/pins/pi.py", line 101, in pin
    pin = self.pins[n]
          ~~~~~~~~~^^^
KeyError: 17

During handling of the above exception, another exception occurred:

I Understand that this is because the hardware for rp5 is different but is there a possible method for doing this on the rp5.

Any help would be greatly appriciated

Raspberry Pi Legacy Tools Add-on

I would like to know the reasons why the RPi.GPIO library was dropped from the Raspberry Pi Tools add-on. In my opinion, this is a mistake. I'll explain. I am the author of the OLEDproc plugin. It depends on several libraries, including the luma.oled and luma.core libraries. And therein lies the trouble. The luma.core library needs the RPi.GPIO library to work. I am convinced that it is unthinkable and also pointless for me to create some clone of the luma.core library, which would use, for…

It looks to me, that you are using LibreELEC 11. For RPi5 support, LE12 and the corresponding rpi-tools are needed. With a recent version of gpiozero the SoC detection should work automatically, but you can force that:

Python

# workaround for lgpio issue
# https://github.com/gpiozero/gpiozero/issues/1106
os.environ['LG_WD'] = '/tmp'
from gpiozero.pins.lgpio import LGPIOFactory
from gpiozero import Device, LED
Device.pin_factory = LGPIOFactory(chip=4)

Alternatively, this should do the same, like your python script.

Bash

#!/bin/bash
/usr/bin/pinctrl -p GPIO17 op dh pn
