USB3FPGA

Is USB3FPGA also available with Delphi drivers or can this be converted?

There's no direct interface to delphi implemented. I'm not sure which version of delphi is used and which versions support .NET, but we have an interface to .NET 1.1 which may work with delphi as well.

In addition to this, there's a C wrapper, which allows the access to the API using a DLL which contains simple C function call. IMHO it's possible to call these functions from delphi in a really easy way. (http://www.drbob42.com/delphi/headconv.htm)

Hello!
I am trying to write linux driver for USB3FPGA device. It will be libusb-based shared object file which will export all the same calls from windows dll. But on this moment I have no document which describe communication between device firmware and dll. I do not need any sources (neither firmware or dll) only protocol description needed.
Looking forward for your cooperation.

Pavel,

we dont distribute a document like the one you ask for.
I you want to use LINUX, consider using the EFM 01 or USBV4F boad.
They work with the Cesys UDK and will run under Linux.

Use of USB2FPGA board

Hi, I am asking a hint. Looking at the board I have an idea, but I need someone to help that I am not heading in the wrong direction
My need is to interface a microcontroller (16/32 bit) doing is things with a PC. I was thinking to use the SRAM as Dual Port ram for creating a fast data exchange area, but without use much microcontroller time (in my head microcontroller should simply use this RAM for reading and writing data ) and have no wasted time in communication with pc, because this is done by FTPGA & Cypress USB chip. Am I correct? is it possible to transform the SRAM in a Dual Port SRAM using FPGA logic? of course I mean a real DP-ram with transparent access from both sides. Thanks a lot to anyone can help me or give me suggestions. Gianni :)

Hello Gianni,

a lot of things are "possible". That is boon and bane of FPGA technology ;-) .
Host-PC communication is done by Cypress USB controller and FPGA design. No additional external logic is needed for that. FPGA is used as glue logic in many applications, i. e. for connecting D/A-, A/D-converters, other intelligent digital circuits ...
External SRAM sharing could be done, i. e. by implementing a multi-port external memory controller. Of course bandwidth would be reduced on every channel.

Best regards

interfacing matlab with fpga

Hi,Iam using x2s_usb .i have to transfer data from matlab to FPGA using usb port. the drivers available with it r for windows 2000 and 98 .how can i get drivers for window xp

and is thier any possibility to connect matlab and x2s_usb using visa.

Hi Qurat,

The X2S_USB is obsolete since a few years.
There is no driver for Windows XP available.
Please use a newer board for new designs.
