Hi Jessie,

When asking for assistance, remember to provide all data relevant to help you find a solution. Since the error code is undefined it would be a good idea to post your code and a screenshot of the error message. Also, it is important to post the question on the appropriate board. I2C related questions go to the Automotive and Embedded Networks board.

Double check the manual from the device you would like to read/write from because you may be having problems related to syntax.

Regards,

Alejandro C. | National Instruments
