AD5040, AD5060, AD5061, AD5062 and AD5063 evaluation board software commands


This discussion explains how to use the new dll library available for both Windows 32 and 64 bits OS.

We aim to provide a detailed explanation of the dll functions and the commands associate with each evaluation board.

This discussion WONT provide any more specific example than the .vi and VB6 code attached.

We are not software developers so for any other software platform, don’t ask please.

If you have some question you can use any search engine available in the web.

Before start you must install, ADI_PDA_Drivers.exe

The dll can be found in the next path:

“Program Files\Analog Devices\USB Drivers\ADI_CYUSB_USB4.dll”

Before continue, the dll has been developed in C++ so, some clarifications

-          The sign “*” before the name of the function means pointer

-          UInt: unsigned integer, 4 bytes

-          Int: Integer, 4 bytes

-          UShort: unsigned short, 2bytes

-          Char: char, 1 byte

-          UChar: unsigned char, 1 byte

The three first functions are used to connect with the board and have to be called in the order they are presented in this document.

  • Search For Boards


Function prototype:

Uint  Search_For_Boards (uint VID, uint PID, uint *Num_boards, char *PartPath[]);


This function searches the PC for USB devices that match the requested VID and PID.
It returns an error (zero for non-error) along with the number of matching boards found and a path address in a buffer for each of them.

The PartPath returns the path for each board found in the PC that match PID and VID.

Ie. Num_boards = 2,

Path for the first board -> PartPath[0]

Path for the second board -> PartPath[1]

VID : 0x0456

PID : B201

  • Connect

Function prototype:

Int Connect(Uint VID, Uint PID, char PartPath, Uint *Handle);

The PID and the VID are the same than before.

This function connects with the board at address path after making sure that it’s still the correct board (checks PID & VID). A handle is returned, along with an error variable (zero for non-error). The handle is the unique identifier for the PC-Board connection.

PartPath is a single location from the previous array, typically PartPath(0).

  • Download Firmware


                Function prototype:

Int Download_Firmware(Uint Handle, char  pcFilePath[]);


This function programs the uC. The pcFilePath is the path where is located the hexadecimal file (included in the attached file) to program the uC. The char array should be null terminated (finish with 0)

  • Vendor Request

Function prototype:

Int  Vendor_Request(UInt  Handle, UChar Request, UShort Value, UShort Index, UChar Direction, UShort DataLength, UChar *Buffer[]);

This function sends commands between PC and board. The command table is included in the hexadecimal code that has been downloaded previously.

Each command requires different parameters for the execution. The list of commands available for both boards is explained below.

An error value is returned (zero = no error)














Low_Data: 16 bits LSB data for the shift register

High_Data: 8 bits MSB data bits for the shift register

  • Disconnect


                Function prototype:

Int Disconnect (Uint Handle)

This function closes the connection PC – board.

If do you think I miss something just let me know.
