Data transfer

[Altera_Forum]

After having captured data from an ADC and stored it to the SDRAM on the DE0-Nano, what's the best way to transfer this data to the PC?  

 I am currently just sending it over the JTAG UART using printf commands, but this is very slow and because I have to use the nios2-terminal I can't do anything more low level. Presumably I would see a speed increase if I just used a UART out to the pins and then a serial-USB adapter. Does anyone have any other suggestions?  Thanks  Bert

WIthout really doing much work, you could add the JTAG Avalon-MM Master and switch over to writing TCL scripts within system-console to directly grab the buffer contents out of SDRAM.

Using these cables allows you to avoid using any Altera tools for communications.  http://www.ovro.caltech.edu/~dwh/correlator/pdf/ftdi.pdf  http://www.digikey.com/product-detail/en/c232hm-ddhsl-0/768-1106-nd/2714139  Cheers, Dave
