New user trying to run a Digispark Attiny85 board with A/D experiments. I am seeing Tools>port greyed out so it seems drivers are wonky. Tried installing DPinst 64 ...no help. If I click on serial monitor the attached error appears. saying "Board at is not available"
The right board (Digispark) is selected. Actually I seem to be able to flash sketches like "Blink" ok.
What is up with the serial monitor??
Any help would be appreciated. Any appropriate blogs or Youtube videos?

I suggest that you read the complete article; it gives someideas to work around it.
Note:
I have no experience with DigiSpark or ATTiny85.
Thanks kindly! Problem solved. Forgot to consider the Attiny85 just has a simple boot loader and there is a Digistump wiki.
I got the example from a web tutorial: https://www.instructables.com/ATTiny-Port-Manipulation-Part-2-AnalogRead/
Should have been more cautious as there was no follow up video or summary to verify use on Attiny85.
Anyhow all is well now!
