Hello everyone,
I just updated to SM 1.6 and I have issues with python scripts running raspberry GPIO pins.
I use gpiozero to move a DIY servo dust cap and rpi.gpio to operate an EL panel with PWM commands for flats.
These scripts work just fine if launched in shell and until SM 1.5 also worked in Scheduler, Capture and Dome Scripting modules.
I tried all I could to thoubleshoot this issue, I hope that someone may halp figuring out what it might be... thanks!

Maybe you need to install some packages? Can you post a sample small script I can test?

Hi Jasem and thanks for the reply,
I use very simple scripts to open/close the cap of the telescope and turning on/off the flat EL light, I attach the code for opening the cap (please unzip as I cannot enclose .py files).
This code is running without issues if I launch from shell with command "python2 open.py" therefore I don't think I miss packages to install...
Thanks for your help!
Fabio

It's possible this is related to pytbon2 which is deprecated? it's not hard to migrate to Python3

Sorry Jasem, it was just a typo, I already use "python3 open.py" command

Did you reinstall gpiozero package? it doesn't come with Stellarmate.

Yes, gpiozero is installed in its latest version 1.6.2-1

Running this as sudo makes a difference? any issues reporting on dmesg or journalctl -f ?
 

I just tried, both commands return this error:
v3d fec00000.v3d: MMU error from client L2T (0) at 0x5621000, pte invalid

I don't think that's related. Running as root, same issue? Could be also some permission issue. Could there a conflict with pigpiod? There is a service running... maybe you can turn that off

sudo systemctl stop pigpiod

then test again?

sudo systemctl stop pigpiod did not change the behaviour:

- script runs ok from shell with "python3 script.py" (both as stellarmate and root)
- same script fails in capture/scheduler/dome module with error message in INDI Control Panel messages box

I agree that it seems a permission issue but I do not understand why this is happening only though ekos

What if you change to:
Does it make any difference?
