MAX5388 Evaluation System
The MAX5388 EV kit software GUI shown in Figure 1 is
a Windows program that provides a convenient means
to control the MAX5388 dual potentiometer. Use the
mouse or press the Tab key to navigate through the GUI
controls. The correct SPI write operations are generated
to update the MAX5388 internal memory registers when
any of these controls are executed.
