Error executable

[lleida]

Hello. 

When executing the program with emulator of Pocket pc 2003 it leaves me this error: Unsupported control-knob, 1640. 
It doesn't cause it to him. 

Can somebody help me?

The program reads of the port COM the sentence nmea of the gps and it extracts a part of the sentence.

Thanks, Greta

Hello Greta,

If I build a executable from your LLB it runs OK !  (LV7.1 and XP)

In your main VI you have the selection for COM port and baudrate inside the while-loop without a dataflow. In the way you build it you have in the while-loop your own sub VI, a case for the baudrate and the com-port open function. The order of execution of these 3 is random !!

It is better to open the COM port outside the while-loop. You only have to open the port once (unless you want to change COM port number and/or baudrate during execution) I don’t think it is the cause of the problem with the ‘control-knob’ but it will lead to other problems.

You also should consider using the VISA serial function.

Exe and changed LLB are in the ZIP

Hello KC.   

With LV7.1 and XP doesn't work me. I have changed COM to VISA and now if it works me with LV7.1. 

If I compile it with the Pocket pc me continuous leaving the error: Unsupported control-knob, 1640. 
Do you know that it is this error? 

Thank you.

Hello Greta,

No, like i said I don't think the possible errors in your diagram have to do with your error.

Sorry, can't help with this error.

A suggestion: replace the controls on your frontpanels (all VI's) with LV controls even it is the same one. Perhaps one of them is causing the problem.
