GENERAL DESCRIPTION

AKD5374-A is an evaluation board for AK5374, which is a stereo A/D Converterwith a USB 2.0 interface.

The AK5374 can be tested easily on the AKD5374-A, as the operation of the device is compatible with

USB standard audio class. The AKD5374-A has not only an external audio interface, but also an external

EEP-ROM that all descriptor contents are stored and customizable.

Software Manual

 AK5374MAPPER.exe

1) General description

AK5374MAPPER.exe is a tool of creating a register setting file that is written to EEPROM on the AKD5374-A.

The program can not only display register settings written from a register setting file, but also change the register

settings directly.

2) Explanation of main window

When runs the program, the window as shown blow opens.

Figure 10. AK5374MAPPER General Setting

A: The top menu can be switched by “TAB” key.

B: Click this button to open a register setting file(.txt), and display will be changed after reading the file.

C: Click this button to save the current register settings as a setting file which has a fixed name

“AK5374_register.txt”.

D: Click this button to output a writing EEPROM file as a text file (.txt) which has a fixed name

“AK5374_eeprom.txt”.

E: Click this button to output a writing EEPROM file as a binary file (.bin) which has a fixed name

“AK5374_eeprom.bin”.

F: “Set All” button must be clicked after changing codes or values in edit boxes.
