Is this library compatible with Arduino Trinket?

I get errors when I verify the sketch:

Hi,

I do not usually use the ATtiny85 but the architecture is different from the tutorial's example (e.g. the RedBoard with ATmega328P). The ATtiny85 uses a different I2C library since it is not a fully Arduino-compatible. This is why you are seeing the errors.

You should stick with an ATmega328P-based microcontroller to save yourself the trouble.
