Thanks for the info! I had a colleague who was trying to test the CCS811 on Arduino and it wasn't working, and I found it was clock stretch so I assumed it didn't support it. He must have been using an old release.

@QuickFix You are right that i am not able to compile a simple blink sketch yet.
Have mostly been playing around with othere people there codes.
Thanks for the link to a other code, will try that out.
