<![CDATA[Ultrasonic I2C module and using port B and Port C on Core2 for AWS with the included library]]>I have an Ultrasonic I2C module and am trying to use it with the AWS Core 2 device. It works fine on port a, but am trying to use port b or port c for the I2C commications. I am using the Arduino development environment and the code in place that works with port a is this:

SONIC_I2C sensor;

sensor.begin(); 
newvalue = sensor.getDistance(); //this is returned in mm
CoreS3.Lcd.printf("%.2f mm", newvalue);

I do not know how to do the same with the sensor plugged into Port B or Port C?

thanks for any assistance!

I did not there was a different port version of the sensor?

Port C is attached to dedicated UART pins.
For port B you need the PortB version of the sensor or use a the PaHub .

Sorry
