Thanks for the reply.
So far I am testing on a digispark-clone (URL see later) or on a "naked" ATTINY85 (flashed with an Uno).
The digispark-clone runs with 16.5MHz (default) and the ATTINY with 8MHz (thanks for this hint).
The library was loaded via Arduino-IDE:
- name=TinyWireM
- version=1.0.0
- author=Adafruit
- sentence=I2C library for Trinket and Gemma, adapted from BroHogan's code on Arduino Playground
