hey i want to shrink one of my projects and use an attiny85. i only need the two pins for the RTC and one for a PWM output.

i was thinking about getting the tinywire library and editing the RTC library from adafruit to work with the tinywire library. would this work?

Core so you can program the ATtiny85 the Arduino way...

I2C library so you can communicate with the RTC...

editing the RTC library from adafruit

I think BroHogan or carl47 has already done something similar.  Try searching the forum for their monikers and some keywords.
