This section will describe the software interface required to communicate to the 
DN9002K10PCI. In addition to reading this section, you may chose to modify the provided 
software (USB Controller and AETest_usb). The source code for these programs is on the user 
CD. These programs collectively implement all of the available controls on the 
DN9002K10PCI. 

6.1

 

Connecting to the DN9002K10PCI 

Depending on the operating system, there are different methods of obtaining a software handle 
to the DN9002K10PCI in order to access it from software. 

6.1.1

 

Windows XP 

What driver is this? It’s the EzUSB driver. 

HANDLE handle = CreateFile(“\\\\.\\Ezusb-0”, GENERIC_WRITE, 
    FILE_SHARE_WRITE, 

NULL, 

OPEN_EXISTING, 

 

 

 

 

0, NULL); 

The “EzUsb-0” device name is registered with Windows when installing the EzUSB device 
driver. The .ini file provided with the driver causes the driver to be assigned to any USB device 
with VendorID=0x1234 and ProductID=0x1234. 

The HANDLE object returned by CreateFile is suitable for use with DeviceIoControl(). 

6.1.2

 

Windows Vista 

Testing was not complete at print time. [email protected] 

6.1.3

 

Linux 

To use USB in Linux, use the provided usbdrvlinux.c file provided on the user CD in 
AETest_usb/driver 

Connecting to the device occurs using the driver’s usb_open function. 

int handle = usb_open(0x1234, 0x1234, 0); 

 

6.1.4

 

Communication 

The USB interfaces that the DN9002K10PCI presents are separated into two types: The 
Vendor requests, and the Bulk Transfers. All other types of USB transactions are not supported. 
The vendor requests are low-bandwidth control signals used for controlling the board settings. 
The Bulk Transfers are used for configuring and reading back FPGAs and reading and writing 
to the main Bus interface. 

6.2

 

Vendor Requests 

Most of the “control” functions available over USB are accomplished using a “vendor request”. 
Programming a USB vendor request is out of the scope of this document, but you can copy the 
code provided in the USB Controller program.
