Dear All,
For my application, I'm using a Spartan-3 Starter Kit Board, with a microblaze microcontroller (uart, timer, bram, etc).
I need the microcontroller to control a few digital lines connected to somme discrete logic on the outside of the board. As far as I can understand, and since those lines don't need to be fast, the easiest way is to hook them on the OPB via a GPIO module. My question is how to do that.
I think I wave to create a custom OPB peripheral using the XPS wizard, and then edit the created VHD files, as it is donne for a "regular" IP, but in this case connecting the registers directly to signals, noting more, but i'm not sure. Is this correct? Can anyone direct me to a tutorial.
Tank you very much
