FSK Demodulator using PCI 5640R (FPGA realization)

[Nikita]

Hi to all,

I'm just starting work with FPGA module Labview. I have made the example project and programm it to FPGA and also I've found an example of FSK Demodulator but it was realized not in FPGA. I have to make 2-FKS Demodulator (low frequency) using FPGA Virtex 2 Pro which includes in tranceiver PCI 5640R.

Please advice is it possible to make it using FPGA library or where can I check an examples of such FPGA realization of Demodulator?

Best regards and thanks,

Nikita

Hi Nikitha,
i seen your Q's in so many posts.
tell me what you need exaclty.
now i am also working on ni 5640r.u can find here(http://forums.ni.com/ni/board/message?board.id=ifrio&message.id=670&query.id=49182#M670)
if your problem also relate to above one we will help together.
my application is i need to generate some modulation using ni 5640r card.
i didn't tried demodulations.all most all i completed modulations.

Thanks & regards

Hi, sorry for so late answer,

Actualy I'm working with 5640R and I need to use HDLNode for FPGA realization FSK demodulator.VI. Do you have any tutorials for using this block? And is it possible to realize any schematics (*.VI) using HDLNode in  FPGA?? 

Best regards,

Nikita

Hi Nikita,

Have you seen this tutorial? It gives a step-by-step on implementing an FIR filter using the HDL interface node. While this is a basic example, it should give you the fundamental tools needed to take the next step in your application. Since this tutorial is geared towards the FPGA on our cRIO and R series products, you will need to adjust some parameters to make it work on the 5640R. Reference this forum for how to make these changes.

I would also highly recommend studying the help files we have for the HDL interface node which will give you more detail on how the node is used and what is available with it. This help file should be included with LV FPGA, and can also be found online here.

Finally, we have some IP examples for RF applications available at www.ni.com/ipnet. You can find examples sorted by application type.
