If this is the documentation for the development board what have you done to convert it from the USB serial device to an i2c device.
I guess you have read 5273 as 5372.
If the OP has connected the evaluation board up as in the PDF tutorial he attached in his first post, then the I2C scanner should have found it and it could not be much simpler.

. . . I did a continuity check on the pins to make sure I have the right pin out. Do you think this could be part of the issue?
I'm guessing it is a wiring issue but what did you use here for the continuity check (unlucky if it was an insulation tester) ?
Do you have any other I2C devices you can check with the I2C scanner (eg a Real Time Clock module) ?
