Testing Tiny85 with a OLED display, it does not work, I'm thinking the problem is in I2C. T1709 also fails. Testing with Tiny84 also fails.

I Attach all the documentation.

Tell me please.

Seems that these libraries are using the USI interface which is not implemented yet.

I'm thinking... Does this mean that I2C doesn't work on the Tiny84 and Tiny85?

These devices don't have a TWI module, they have an USI (Universal Serial Interface) which contains some hardware that can be used for several types of serial communications, but needs to be controlled by software.

In any case I2C can work in any MCU if generated completely by software.
