I am using Raspbian Stretch with Raspberry Pi 3 and skywriter library is 0.0.7

Traceback (most recent call last):
File “test.py”, line 10, in

Can someone suggest how to fix this.

Is this a Skywriter? (IE: not a Skywriter HAT) Could you post some pictures of your wiring?

@gadgetoid I apologize, its a skywriter hat. I should have mentioned that. So I’m guessing I don’t need any wiring. I just stack it on top of the Pi.

Absolutely. What type of Pi is this on?

5

It was a Pi 3. Turns out the hat was non functional.

Did you get a working replacement?
