Cyclone 4 Jtag - with VHDL

Ok,

I am trying to make a form (visual C or C sharp), with buttons that enables me to run different VHDL codes on DE2-115.

For this I want to use the JTAG interface (and not UART etc.)

So Far I understand that I can use the built in FTDI chip on board DE2-115, with PC- DLL file to communicate

The Red leds are only to see that the board is working (binary counter at slow frequency)

Changing message from time to time (because of some progress:))

Now - Jtag primitive that I have took from LPM - seems to work opposite ?!

Seen that TDI - > Is an output?

and TCK as also output (and not input as I expect)

So I have connected shift register -> Serial in, parallel out to see the actual bits out

But when running I see all LEDS are on? - why? is the JTAG active all the time? from where does it get any clock?

Again I expect to see according to my DATA IN (later via FTDI DLL) the green led in some state

See attached file

Thanks,

Roee
