Fast & Large block data transfer over USB - DE1/DE2 ?

Hi Beau,

I have completed a GUI to drive the PC to FPGA VHDL code ...

Awesome. I'm traveling at the moment, and only have a dial-up connection (how ancient), so I'll wait until I get a real internet connection before checking it out.

Even sold my first copy !

Nice!

And I expect plenty of pointers as to where I could do things better ! :)

Next week, I'll check out the code and concept and give you my review :)

Ping me next week some time, if you haven't heard from me.

Cheers,

Dave

how easy would it be to include a EPCS4 configuration eeprom to the MorphicII fpga module design? would dwh@ovro.caltech.edu test .c upload problem need any amendments to work with the EPCS4

im very new to this / very interested! :)

Such a configuration eeprom is not really needed - the MorphicII fpga module is programmed over the same USB as transfers data, and it only takes about 100ms for the upload and program.

There is an example binary GUI with binary VHDL code that programs the MorphicII and demonstrates transferring data over the USB at full USB2 rates, at :

you can transfer your data by usb but if you can also the data by using networking.

Can you please explain more ?

I am using all the expansion IO for a Terassic ADA module - I did not think the DE1 had a LAN connection ?
