This is not working with
Arduino UNO R3
Arduino IDE 1.8.5
MacOS 10.13.4

Installed as described ('librairies' folder)
Replaced _#include <Wire.h>_ with _#include <WSWire.h>_
Corrected minor errors:
'Wire.write('\0');' => 'char c = '\0'; Wire.write(c);'
'Wire.endTransmission(true);' => 'Wire.endTransmission();'
Compiled (with AVR ISP)
Uploaded to Arduino

=> No I2C communication anymore

Replaced _#include <WSWire.h>_ with _#include <Wire.h>_

=> I2C communication working

The twi head in this lib is an outdated one. Are there some one going to fix it?

Sorry for my poor Eng.

There is no function to set clock frequency as Wire library. It seems fixed at 100000.

Hi. In recent versions of Raspbian something must have changed, so that I now no longer can communicate between a Raspberry Pi and an Arduino over I2C.

When using the original Wire library it works however.

More technical detail:

I used a logic analyzer and could conculde the following:

• The Arduinio (used in slave mode) recieves write events and acknowleges them
• But it doesn't read nor acknowlege read events.

If it helps I can attach the data I capatured with the logic analyzer.
