Labview Drivers for Wireless Sensor Networks

[anilhk]

Hi Nitin

I have checked the same but still getting the same error . One more thing i noticed here was

The VI's which i am using are the examples ... ie they are not created by me .however I am using these VIs for my actual setup which i have done n my lab.

Will that be a cause of concern ?

Hi Anil,

These VIs only require the right device ID (eg COM1) and they should work fine. This particular driver is not NI Supported/Certified (look at the top left hand corner) and there may be reasons why it may not work. However, presently the best way to find out why your VI is not working is to activate NI-SPY and perform a good capture as shown here.  Post the captured log in this forum. Another question I had was, which of the three examples are you using?

I've also noticed that this project was made for an older version of LabVIEW. It would be good if you could open the Project in LabVIEW 8.5 and save it (assuming you are using LabVIEW 8.5). When you save it, it converts the code to be compatible with LabVIEW 8.5. After completely closing and opening LabVIEW, you can view the VIs that this driver provides in the Functions Palette of the Block Diagram under Instrument I/O » Instrument Drivers » Crossbow XMesh WSN

Hi Nitin

Will run the NI-SPY capture results and will send across the output asap.

I am currently using "Read Data and Display Health with Variable Rate.vi". I have opened the VI and clicked on the run button which gave me the error which i have listed above ( hope this is the correct method to execute the example) .

Post saving i was sucessfully able to see all the VI's which were created .
Some of them were
Create stream
Start Stream
Stop Stream
Clear Stream
Read
Advanced streams etc
the path was however Input - Instrument drivers -Crossbow-xmesh-wsn -

I have a query regarding the installation of drivers ..
as of such i have not installed the drivers, the drivers which i have downloaded were
for sensors and gateways

both were in 2 seperate directories  but with the same name ie crossbow_xmesh_wsn

thus i just copied and pasted the directory in the path C:\Program Files\National Instruments\LabVIEW 8.5\instr.lib
hope this was correct .?

Hi Anilhk,

You are right. There is no specific installation process. You unzip and place the file in the above mentioned folder. Also, what version of NI VISA do you have. This driver needs atleast VISA 4.0. The NI SPY capture will be able to give more information regarding the issue.

Hi Nitin ,

your reply has raised one more query in my mind ..

While downloading the drivers the site offered me 2 links .. 1 for the gateway drivers and the other for the sensor drivers ..

on downloading and extracting i found that both the downloads were getting extracted by the same directory name , thus i was not able to copy both the drivers at the same location .

can i rename the directories to any other name or is there any other method to do that ?

what version of NI VISA do you have.This driver needs atleast VISA 4.0

Have got no clue about this can u let me know how do i check that ?. If i dont have it how do i download it ?

The NI SPY capture will be able to give more information regarding the issue.

I checked the same was not able to locate that software in Labview.. googled the same but in vain ..from where i can download it and run

i am currently using 8.5 evaluation version

thanks

Hi Anil,

If you downloaded the driver from Instrument Driver Network we only have one driver available located under Download Process.

For checking the version of VISA you go to Programs>>National Instruments>> VISA >>Documentation

or you can go to Add or Remove Programs National Instruments Software and check there.

Below is the link to VISA drivers on Windows

Hi JJP377,

I have downloaded the drivers from the National Instrument site , what i ment was .. in Wireless Sensors we have 2 devices .

1.Sensor

2.gatway  , thus we needed the drivers of both , however both have the same directory name ..

thus wht needs to be done , which one to be installed ?

thanks !

Hi Nitin

Pls find the output of Ni Spy , and this time around i did not got any errors .. but i am not able to see the output of the sensors on my screen which i suppose is the purpose of the example given

thanks !

Hi Anil, did you get your problem resolved? 

I'm having the same exact error.  I purchased the crossbow professional kit and downloaded the drivers for the MICAz/MICA2 processor which also includes the MIB520 USB programming board.  I downloaded these drivers directly from www.ftdichip.com because the CD that came with the kit only had drivers for XP and 2000, but not for VISTA.  So I went online and downloaded the drivers which included VISTA.  Once I plugged in the USB drive, it searched automatically for all the required drivers and all was downloaded successfully (according the little window).

The LabVIEW drivers are also downloaded.  But when I run the Read Data and Display Health.vi, I get the same error as you, Error 8003.

Can anyone please help me on this issue?

Thanks.

Hi anilhk,

It's odd that you are not getting the error now. There may be a possibility that something is wrong with the VISA installation or with the way the devices are connected/configured on that particular system. Try running the program with NI Spy and without NI Spy. See if you get any errors in either case.
