Hi,

I am trying to access a QuickLogic FPGA via JTAG. I am using a FTDI
DLP2232M-G (and associated FTCJTAG api) to connect to the device.

So far I have been able to read and write data to the device
sucessfully, or at least i think so!

My problem is, that presented with a read / write API functions I have
no idea as to what I *should* be writing to or reading from the FPGA
and to which registers (instruction / test). My goal (at least for
now) is to sample the state of every pin on the device.

My question is this: does anyone know the commands needed to sample
the state of every pin on the FPGA and if so how do I interpret what I
read back?

Please bear in mind that I am a software engineer and know virtually
nothing about FPGA's and very little about JTAG (dispite reading the
IEEE standard and understanding very little).

Thanks in advance for any help.
