SSM2529 REV 1 EVALUATION BOARD OPERATION (PRELIMINARY!)
Description of Setup:
The SSM2529 evaluation setup consists of the following:
1) A fully integrated SSM2529 evaluation board, EVAL-SSM2529
2) Analog Devices USB-to-I2C adapter dongle, EVAL-ADUSB2Z.
The SSM2529 can operate in stand-alone mode without the need for I2C control, as shown in Figure 1. In order to
evaluate full functionality of the SSM2529, the user must use I2C. A GUI has been developed using the SigmaStudio
development platform. The ADUSB2Z dongle is able to interface between the GUI and the evaluation board, as
shown in Figure 2.
