compactDAQ single point continuous acquisition

Hi,

 

I'm using a compactDAQ (USB) with an analog input module (100ks/s) and one digital output module. I need to switch an output as soon as my measured voltage has reached a certain value. Therefore I have to read every single sample as soon as I get them in order to respond on them immediately. I tried to use the daq assistance and configure it as "single sample on demand" and than just put it inside a while loop which will make it initiate new readings continuously. I also wired a "false" constant to the "Stop" input which significantly increased the sample rate. Still I think it is kind of slow though, with nothing other running I reach a sample speed of 700 sample/second. I'm new to labview and pretty stuck. My question is if there is any way to get a higher sampling rate, perhaps the use of the daq assistance is not optimal in this case? Isn't there anyway to initiate a "continues samples" and read out the buffer during the readings (i.e. not wait until all samples are done?)

Thanks in advance

 

Regards Linus

In the help menu look for find examples.  That should point you in the right direction.
