1.0.8 does not work with Arduino 1.8.5 / Mega256

[rtammer]

Hello,
The Arduido 1.8.5 IDE (Mega 256) does complain about Wire.begin(0,2).

According to the docs there is no second parameter to Wire.begin();.

Hello Rainer,

Thank you for point it that out, I haven't noticed it. The Wire.begin() can have a second parameter, but it works only with the ESP8266 board. I made a mistake implementing this function on version 1.0.8 and, as you have already noticed, it creates problems when you try to compile with the regular Arduino boards.

I already corrected the .cpp file on github a while ago, but forgot to create a new version. The Arduino Library Manager still has the wrong version, which probably caused the error with your board.

You can download the new 1.0.9 version on github right now or wait an hour or so for the version to be available on the Arduino Library Manager. The version 1.0.8 will be deactivated.

Please let me know if you are still having difficulties compiling this library with your board.

Best Regards,
Thiago

Hello, Thanks very much for the fast answer/update. Did you see the second issue I have entered on github (missing cast)? Bye Rainer

Hello Rainer,
I just saw your second issue, but I couldn't reproduce the error message. Although I don't own an Arduino Mega, I've set the Arduino IDE to compile to the ATMega2560 and I could compile the library version 1.0.9 without any problems. Did you try the latest version of the library with your board? Perhaps both issues were related...

Best Regards
Thiago
