Digispark and TM1637

[aand]

I'm trying to get a four digit 7-segment LED TM1637 display to work on my digispark.  I've already used these on several Arduino's and ESP8266 devices, but I'm getting no where on the digispark.  Am I missing something obvious?  I've googled around and haven't found any examples on a TM1637 on a digispark, although I would have thought it'd be fairly common.

I'm not familiar with that chip, but a quick search for TM1637 Attiny85 came up with some results... including a video and an instructable... so I don't see why it wouldn't work with the Digispark since that is an Attiny85 at heart. Maybe the source code from the instructable will give you some ideas as to what's going on?
