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.
