GUI Software and Operating Descriptions

7 GUI Software and Operating Descriptions

Once you have connected the AMC7812EVM to the USB-MODEVM motherboard and provided power to

the motherboard from a USB port on your PC, start the AMC7812EVM-PDK software; correspondingly,

the GUI should display (refer to Figure 4). The common software settings, controls, or display sections for

the AMC7812EVM-PDK are arranged at the top and bottom of the GUI.

There are also five tabs in the middle and main section of the GUI, designed for users to easily access the

registers of the AMC7812 that are specified for a particular function of the device.

7.1 Common Sections of GUI

At the top left-hand side of the GUI, the location and version of the firmware are shown (refer to Figure 4).

At the upper center of the GUI, the rectangle box labeled Global Alarm displays the status of the

AMC7812 GALR bit. The global alarm box is dimmed unless an alarm event occurs; if this happens, the

box turns red. See the AMC7812 data sheet (SBAS513) for more information about the global alarm flag

GALR.

The two buttons at the upper right-hand side of the GUI can be used to perform a software reset of the

AMC7812. When you click on the SW Reset button, the SW reset register is written to and a reset

operation is implemented. See the AMC7812 data sheet (SBAS513) for more information about the

software reset and SW Reset register. To stop running the EVM evaluation tool, you may either click on

File-->Exit button or click the red X at the top of this window.

In the middle of the bottom area of the GUI, the control button can be used to turn the AMC internal

reference circuitry on or off. The internal reference voltage can be measured at the test point (TP) of

REF_OUT on the AMC7812EVM board; the location of this area is indicated in Figure 5.
