Hello I know this is a old post from a few months back. But I'm also trying to get the oled to work on the Attiny85. I tried repeating all the same steps as Bitto has done. But i get different errors.
Sketch uses 4300 bytes (52%) of program storage space. Maximum is 8192 bytes.
Global variables use 190 bytes (37%) of dynamic memory, leaving 322 bytes for local variables. Maximum is 512 bytes.
avrdude: Yikes! Invalid device signature.
Double check connections and try again, or use -F to override
this check.
An error occurred while uploading the sketch

This is the same library that belongs to olikraus Oled u8g2. But I'm not sure what is going on. Can someone please help me?
