Luisa,

you can communicate and debug via the JTAG interface on the DE2-70 board. This can be done by making a Nios-II architecture and adding the JTAG-UART to your Nios architecture in SOPC.

The protocol to communicate from the DE2-70 to the outside world (your PC) is of course something that you decide on by your own protocol.

The board has an example application, but as far as I know no source code for the PC part. The TERASIC_JTAG.dll is provided as an example.

In case you would build on the exisiting application, you would have to reverse engineer the TerasIC protocol from the Nios-II C-code and write your own PC application. Also the way how the hardware is made and linked to the Nios processor will only allow you to get this video communication at a very low transmission speed.

Hope this helps...
