Hello,
I'm starting with Labview, and I have some trouble to make it work properly. I use the student version 8.20.
I have a problem to set the reading time of a TDMS file , whose data must be sent by the analog output of a USB6009.
The project aims to record the signal of an electrocardiogram, and
reproduce it later. I get the signal from the analog input of
the USB6009, (10 samples at 500Hz) and write it in a TDMS data file (REC option ). Execution time loop last of 20ms (50Hz) . Then later,
when the user wishes, he can read the TDMS data file (PLAY option) , and recovers
the signal from the analog output USB6009.
As
the DAQ assistant output can send only one sample at a time, the loop
"PLAY" should go 10 times faster, to keep pace temporal signal
(2ms-500Hz), but I can not set this parameter.
As a result, reading the data takes too long. So for 2 minutes of recording, it takes nearly 3 minutes reading the same
data.
Does someone knows how to set the time to
execute a while loop ? or, is it possible to record in the TDMS
file the temporal data?
Thank you very much for your help.
Sincerely,
Sebastian Avila.
