sample program for RF

[wathan]

Hi all,

Currently my teacher want me to write the program for RF using labVIEW 7.1.Can I take a look some sample program for that?

The RF I using now is 9Xcite OEM RF Module. I really hope that  someone can help me.

thanks

best regards,

wathan

Hey Wathan,

Thanks for contacting National Instruments Support.  This sounds like a cool project.  After looking a bit at MaxStream's website at their RF module, it looks as though there is a driver that you can download.  This driver would be key to using this device in LabVIEW.  This may take some help from MaxStream, but if you can make calls to their driver somehow and get data from th device you should be able to bring that data into LabVIEW and process as needed.  Let us know if you have any further questions.

Hi Kenn N.,

Thank u for your reply.I will try to do as u said. But my teacher said that even i don't have Driver, i can write the program.

Anyway I will try as your way.

For now, can I get some Tutorial & example program for that ?

I may able to write the program after I do some tutorial & make referance to the example program.pls help me. Thank you.

Best Regards,

wathan

Hey wathan,,

You may have misunderstood my meaning. This is a new application you are attempting to write.  It will rely heavily on the manufacturer, MaxStream, and how they implemented their driver.  You have two avenues to pursue, one is to make calls to their driver, if they allow them, or to basically create your own driver.  This second step will also rely heavily on the documentation that MaxStream provides.  If they document things like what the board nees to start up and what data needs to be sent to it's onboard controller to get it to work properly. 

Once you determine what data needs to be sent to the board to get it to function, you will need to determine the means of getting that data to the board.  For instance do they communicate with the board using a serial port, or a USB port, or can you control it with a set of digital lines and then read back the resulting data that the board acquires with another set of digital lines? 

After you figure out those things we can look at how to implement them in LabVIEW if possible.

Lastly, if you have the Modulation Toolkit you can simulate RF communication protocols.  Those examples are found in the Example Finder, or Start >> All Programs >> National Instruments >> Modulation >> Modulation Examples Folder.

Hi Watman and KENNE

your topic is near to  the one i m trying to build now.

as a matter of fact, i m using the X24-009NSC from a compact RIO to transmit wireless data to XStream-PKG. The user manual explain the configuration in HYPER terminal as though, i want to programm it with LabVIEW.

the compact RIO will be embed in an UAV (unmaned Air vehicle) with the transmitter X24-009NSC and the receiver XStream-PKG will be connected to a PC.

I fisrt try to use both device, but i don't have any path to test them. All your suggestion will be welcome

thanks

Hi Ericnya,

Can you provide more information on how you're interfaceing the X24-009NSC with the compact RIO (ie. what c-series modules you're using, etc)? As far as testing the system, I would suggest you to write simple VIs that send some boolean data wirelessly between the cRIO and the computer.

Hi Stanley

in fact, i want to share information between X24-009PKC-R connected to a PC with an X24-009NSC connected to the compact RIO with labVIEW.

The compactRIO has two C serie module the NI9403 and the NI9201.  The compactRIO will receive data coming from sensor connected in the NI9201 and then send to XStream device to be transmit

thanks

Hi ericnya,

Unfortuantely I do not know much about the X24-009NSC and X24-009PKC to give you an solution on how to build the system. As far as programming the cRIO, here are some resources that might help you get started.

You may also want to look at some examples in the example finder (Help » Find Examples...).
