DE1 USB communication

Hello,

I was wondering if there is any way to have USB communication on the DE1 board? I read a few articles regarding use of the Virtual JTAG which seemed interesting (I am yet to try those).

The Qsys tool shows a USB Controller in its components menu. Can this be used to have a USB Communication? I do not know how to begin :confused:

    Cool. This takes the TCP/ IP route. I am starting the tutorial now. :)

    What do you think about using the Qsys USB controller?

    I've never used it. You'd need to read its documentation. For example, it might only be available on the newer ARM SoC devices. Older generation devices do not have USB interfaces. A board like the DE1 might have a USB controller (DE2 has an ISP1362), but a Qsys interface to this is "nothing" more than an interface to the device registers. You then need to interface to it using a NIOS II or your own HDL.

    Cheers,

    Actually it uses the JTAG interface. The TCP/IP example is layered on top of that so that you do not have to use Tcl if you do not want to.
