Serial Communication using Labview with Tiva C launchpad ARM cortex M4

[piZviZ]

I am able  to comunicate perfectly  between labview and launchpad at 9600 baudrate..When i trying to communicate with bauadrate of 115200 labview gives error "specifed state of attribute is not valid"

I tried to communicate with serial monitor comes with arduino and its well work with it at 115200 baudrate...

Awaiting for your replay!!!

Are you talking to the two devices through the exact same port? Do you have some code that demonstrates the problem?

[mikeporter]

Oh yes, how about the data rates between 9600 and 115200, do they work?

Mike...

[piZviZ]

Only data rate working is 9600  between labview and launchpad(arm cortex m4).Where all data rates work between Arduino serial port monitor and launchpad(arm cortex m4).

[mikeporter]

So ONLY 9600/works? That sounds like you aren't setting the data rate correctly on the launchpad.

Since the only thing that changed is the Launchpad, then that must be the issue.  Are you sure this device can handle more than just the 9600 baud rate?  Are you sure you are even setting the baud rate on this device?

[piZviZ]

I am sure that device can work at baud rate above 9600 and i tested it using arduino serial monitor and baud rate of 115200..

Please look at my vi and attached snap of error..

What type of serial port are you using?

For some reason, Windows thinks your serial port is not capable of the baud rate you are trying to select.
