Hi,
Thanks for the resource, I have just tried implementing the fixes provided
in the document, but it still throws up errors,
As per the document, I have added
from gpiozero.pins.pigpio import PiGPIO
Device.pin_factory = PiGPIOFactory()
however, this throws up:
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
Can't connect to pigpio at localhost(8888)
Did you start the pigpio daemon? E.g. sudo pigpiod
Did you specify the correct Pi host/port in the environment
variables PIGPIO_ADDR/PIGPIO_PORT?
E.g. export PIGPIO_ADDR=soft, export PIGPIO_PORT=8888
Did you specify the correct Pi host/port in the
pigpio.pi() function? E.g. pigpio.pi('soft', 8888)
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
Traceback (most recent call last):
File "/home/james/networkerbot.py", line 39, in <module>
Device.pin_factory = PiGPIOFactory()
~~~~~~~~~~~~~^^
File
"/home/james/myenv/lib/python3.13/site-packages/gpiozero/pins/pigpio.py",
line 93, in __init__
raise IOError(f'failed to connect to {host}:{port}')
OSError: failed to connect to localhost:8888
I have tried, as per the error message suggested, tried running sudo pigpiod
,which returns command not found.
I have a feeling its something to do with being inside of a virtual
environment.
Many thanks
James C
