View ArticleRe: Skype Vi fails making a phone call
I found the problem may be due to the labview invoking skype with "placecall" action. This "placecall" starts skype call , not call to a mobile or telephone number. How can solve this problem? Wei Tong

Right click the string control and set display mode to codes display. Then you know what you are sending. try my idea too

Hi agoncalves, I took a quick look at your VI and I see two immediate problems: 1. There is not guarantee that both tasks will reserve before either one starts. This explains your error and why it...

How is your task configured? What sample rate do you have on the task? Is it sampling a finite number of samples or continuously?

Possibly use a FOR loop. Put all of your parameters in arrays and autoindex the arrays going into the FOR loop. Inside of the loop, you could close a relay, read a value, then close the relay....

I have it setup to read samples continuously. I can change the sample rate. It seems that roughly 2000 samples per second on 8 channels gives me the lowest occurance of this phenomenon, somewhere...
View ArticleRe: AI Read Returning Empty Sets
When you setup an analog input task to run continuously, the samples per channel input of the DAQmx Timing VI doesn't tell how many samples to read. It sets the buffer size. In general, you should...
View ArticleRe: AI Read Returning Empty Sets
Thanks. No, not getting any errors. I think I may be able to solve my problem by simply eliminating the timing function. I might not need it in this program.
View ArticleRe: AI Read Returning Empty Sets
No, you really should have the timing VI. Otherwise your DAQ will just sample when you ask it to in software. If you really need the 3kS/s, it needs to be hardware timed and set to continuous...
