7 segment serial display + ATtiny85 + i2c/serial uart

I am trying to make a project with the smallest project controller (an Arduino Uno would be overkill). I was planning to use an ATtiny85, but was not sure whether I would be able to properly communicate between a 7 segment serial display using Serial UART or I2C. Does anyone know whether either of those would work or have any experience doing so?

I have reviewed Sparkfuns tutorial, but since not all functions that work on an Arduino work on an ATtiny85 I wasn't sure whether this project would work

SoftwareSerial should work with the ATTiny85.



I'm not sure how the example code is structured, so you may have to rewrite it if it uses a library that makes assumptions about available hardware/registers.

That makes sense. Thanks.
