AK7719 Evaluation Board Rev.0
GENERAL DESCRIPTION
The AKD7719-A is an evaluation kit for the AK7719; a digital signal processor (DSP) with 4 channels
digital data interface. It realizes an easy evaluation of the audio system by just connecting to the target
product via digital input and output pins. A USB connection is adopted for control interface, enabling to
develop DSP codes with a PC.

CONTROL SOFTWARE MANUAL
■ Setup of the Evaluation Board and Control Software
(1) Power the AKD7719-A-MAIN evaluation board on and connect it with a USB control box.
(2) Connect the USB control box to a PC with a USB cable.
The USB control box will be recognized as HID (Human Interface Device). When it can not be recognized
correctly (e.g., unknown device is connected), please push reset button [yellow] on the USB control box.
(3) Install AK7719.exe to the PC. Then ready to evaluate.
The start-up image of control software is as below.
Figure 3. Start-up Image of Control Software
When the connection of PC with the USB control box is removed, it is required to restart the control software.
