audio input using 5640R

[islamabad]

Hi...

i am aqib

currently i am using pci-5640r, i want to play an audio file in my computer and from that i wanna give input to pci card and subsequently to labview fgpa to perform QPSK modulation and transmission.

plz help me how can i do that

It is no problem playing wav files directly from Labview, and at the same time have full control. Just use the example finder and serach for sound.

Hi Aquib,

You may get more answers to your question if you post on the IF-RIO specific discussion board.

Have you used the PCI-5640R before? If it is your first time using it, I would suggest that you go through the NI IF Transceiver Getting Started Guide, as it will help you get used to the LabVIEW FPGA environment and specifics with using the 5640R.

As far as doing QPSK modulation in LabVIEW FPGA, we do have the LabVIEW FPGA RF Communications Library 3.0, which has examples for PSK modulation, which will give you a starting point. If you have questions on that Library, I would reccomend postion on the board here. 

There is also an example that does the uses the Modulation Toolkit to do the processing on the host computer here. You may also find this old discussion forum useful.

Once you start to work on your application, if you have more specific questions, please post on the IF-RIO specific discussion board, as you will recieve more help from IF-RIO users if you post there.

Regards,

Elizabeth
