Honored Contributor...to use the jtag/usb-blaster to send data from the pc to the development board to control it (i.e using the hyperterminal or something like that to send control characters)? :confused:
Honored ContributorUse SOPC Builder to add a JTAGUART to your architecture. In this way you can communicate via your USB link. The easiest is to use a Nios-II processor, but you can also directly communicate with your slave devices.
Honored Contributorthere is a way for accessing JTAG UART from a C program using cygwin and the dll jtag_atlantic.dll.
This demo has an example of the proposed approach. http://www.nioswiki.com/exampledesigns/highspeedimagedownloaddemoHonored Contributorthanks for your answer and the example, parrado...
i'm gonna take a look on that demo to see how it works the .dll, and how to use in quartus/nios projects. anyway, i've searched for some info on google and i found a c library for usb communications, libusb. do you know about this library? is it possible to use it instead the jtag_atlantic? any kind of information/orientation would be really helpfull to me. thanks in advance.Honored Contributorlibusb permits using USB port from user space. This is a low level library, in that case, you must have on your development kit a hardware or firmware that implements an USB device. In this case you can't use the USB blaster connector, an additional one is needed.
