Evaluates: MAX98396

MAX98396 Evaluation Kit

Communication Tool Bar

The

Communication tool bar consists of control buttons

These controls are always accessible, regardless of the

active tabbed page. The tool bar is shown in Figure 4.

Table 1 provides details about each control.

Connect Sequence

When the evaluation software starts for the first time, the

program automatically connects to the EV System and

attempts to connect to the USB control interface on the

AUDINT3 board. Once the AUDINT3 connection is estab-

the MAX98396 device and populates all detected device

addresses in the

Active Device drop-down list. During

this sequence, the text on the

Connect/Disconnect but-

ton automatically changes from

Connect to Disconnect,

and the status bar is also updated to reflect the current

state of the hardware connection. If properly connected,

“EV System Ready” should be displayed on the right side

of the status bar.

Once the EV System is properly connected, the button

displays

Disconnect and changes function. When clicked

on, the

Disconnect button disconnects the software from

the hardware. The software can also be disconnected

from the hardware by selecting

Device | Disconnect from

the menu bar.

There are two methods to reestablish a connection with

the hardware. The first is by selecting

Device | Connect

from the menu bar. This instructs the program to connect

to the EV system. The second method is to click on the

Connect button, after which the status bar (in the bottom

right corner) should display “EV System Ready” and the

button function changes to

Disconnect, showing that the

EV system is properly connected.

Status Bar

The Status bar is divided into five sections, from left to

right: status and alert messages, device part number and

revision ID, interface name and firmware version, EV sys-

tem connection status, and communication activity.
