Thanks a lot, Lutz! Really great!
After I sorted out, that the I2C-pins used in the Fritzing picture were not the ones used in your code, all worked perfect. Much appreciated!

Hi, some question to this.
1) did you try at frist the scan File i Provide on GitHub? And is it working?
2) whats the Programm you are calling this function /file from. Did you try example 3 from my github repository?
3) this Error is normaly comming from a Timing issu, do you use the i2c Bus in your Programm before, without waiting ? May you need to add a sleep command (>5ms) in Front of the command.
