I2C with the ConnectCore 7U

Does anyone have any experience using the i2c API’s with the 7U? all of the documentation says both that the 7U will support i2c on PortC6 and PortC2, but at the same time all the API documents claim that the 7U’s are not supported.


I used the 7U a few years ago and I seem to remember that it does not support hardware I2C, but there may be a driver included to support I2C with software directly driving the port lines.

If you only need a master it is reasonably easy to do your own I2C by dirtectly driving the ports under software. A slave is more problematic because of the timing requirements.
