UNIHIKER Spirit Level Demo
Matha.Goram 2025-06-01 23:15:17 452 Views7 Replies Trying to run some demo programs on UNIHIKER M10. Some Python scripts work, some don't. In particular, the “Spirit Level” demo script displays the following message:
This feature is only available for unihiker!!!
What is the rational interpretation of this message when it is displayed on the screen of the UNIHIKER M10?
Why isn't the script detecting my board as a legitimate unihiker? Do I need to install or upgrade anything on my board for it to be recognized as an unihiker board?
Thanks for any guidance.
Regards.
This error typically indicates that the pinpong library incorrectly identified the Unihiker. You can try running the command shown in the screenshot to check the output:
LL It's possible that you modified the system's hostname.
To check, run the command hostname in the terminal—the output should be unihiker. If not, please reset it to the default value (unihiker).
It didn't help, but the behavior changed.

# And so on endlessly
Downloaded and installed OS Image V0.4.0 for Unihiker.
Everything worked.
But if I change the Hostname, I get the same errors again. It's very inconvenient(((

On the Unuhiker miniPC, which I ordered a year ago with OS Image V0.3.6 The PinPong library is working.
If you download and install OS Image V0.3.6 for Unihiker, which I received last week, Pingpong does not work.
Could you provide screenshots of the error messages?
LL I have the same problem.
