nexys2 fpga board usb

[vport]

I want to nexys2 board for usb communication. I have complete work on EPP usb communication now i want to use slave fifo on nexys2 board .i have some questions

1) Is nexys2 capable of slave ffio mode

2) how to disable EPP mode on nexys2

3) if there an eaxmple for nexys2 slave fifo so please give me lin thanks

I heard back from an engineer and he pointed me to the SDK adept download. 

Make sure you are using the DSTM demo not the DEPP demo.  

The reference manuals can be found in the SDK download directory under "doc".

Under the "samples" directory, there are C and VHDL files for implementing the FPGA side of the project.

Best of Luck!

Hi vport,

I have escalated this to our support team who will get back to you here on the forum.

Thanks,

Hello vport,

Sorry for the wait.  Can you describe more of what you are trying to do?  I can't help you much without more description.

It sounds like you started with a USB-to-EPP demo, do you have a link?

Thanks,

Marshall

I want to use follwing application note over my nexys2 board but unable to understand follwing lines 

 

https://github.com/AlexWillisson/soc/blob/master/digilent.adept.sdk_2.0.1/doc/Digilent Synchronous Parallel Interface (DSTM).pdf

The order of events when calling DSTM APIs is as follows:
• The EPPEN signal is set low to disable the EPP interface.
• The necessary configurations are applied and the USB controller is put in slave FIFO mode.
• The STMEN signal is set high to signal the enabling of the DSTM interface.

how to disable EPPEN AND STMEN ON NEXYS2 BOARD

For the Adept API to communicate with the FPGA through the cypress JTAG programmer, there has to be bit file programmed on the FPGA.  I cannot find the file that goes with this project.  Did you find it?

I need to contact an engineer that has been around for longer than I have.

Thanks,

Marshall
