Hey Guys, I did a search and I couldn't find where this was answered. So, if someone has already asked this, I'm sorry. I'm in my senior year of school and I just puchased a myRIO. I have had a few measurement classes but I'm not really fimiliar with LabVIEW at all. I'm trying to record my GPS position and acceleration for some testing. I'm basically using the default GPS and Acceleration programs that you can download for myRIO. I have combined them and added a USB write to file program to record the data (I cannot seem to get the DAQMX to work). From the research I have done, I appears that I need to add a VISA Write command right after my VISA configuration icon to increase the baud rate up to 38.4Kbd I'm using the following write buffer comand line $PMTK251,38400*27<CR><LF> Once the Baud rate has been increased, then I can up the sampe rate. So, I added another VISA Write inline. the write buffer command line I'm using for this is: $PMTK226,3,30*4<CR><LF> The program runs fine, but the sampe rate hasn't changed with the above mentioned VISA's added. I have tried multiple Baud rate codes as well as position fixed interval codes. I have changed the loop wait times from 100 to 10 but that doesn't seem to have any affect either. I'm assuming I'm just missing something dumb, but I cannot figure it out. That should be all of the code for the GPS. The rest of the code that you cannot see is the Accelerometer. It is working fine now that I added the filters. Anyhelp you can provide is greatly appreciated. I really need to get this done and I'm stuck.

With the help of Dennis, we got it worked out!

Here is a screen shot of the modification. I have also, attached the vi if anyone wants to see the whole code
