I2C example does not compile

[jerabaul29]

The I2C example (in Arduino IDE, File > Example > Apollo3 > I2C) does not compile for me using the RedBoard Artemis board:

Try SDA on pin 14 and SCL on pin 15 (looking at the schematic). In any case, I haven't had any luck using the I2C pins on-board. Breaking out the QWIIC SDA and SCL pins works ok. These are configured differently in the core so one might be working while the other is not?

Scheduled for v2.0.6, see #368 to preview release.
