Chainable LED not working


So I’ve tried running the example in GrovePi/Software/Python/ with different LEDs, different numbers of them and on different ports. They have never done anything resembling what the script says.

Most of the time one or more of them lights up, and then the first one just flashes blue. I’ve done this without anything else connected to the board. Still same result.

Do you have any suggestions?

Hey jorg.rodsjo,
Can you run: and let us know what it shows.
