how to control the number of cycles in a triangle pattern

[geojj]

Hi, 

I'm quite new Labview programming and finding a hard time coding a simple program. So can someone help me find a way to control the no. of cycles of a triangle pattern.ie, if a button is pressed the code should send a particular no. of waveform Once it's completed the button should toggle back to the orginal state. I have attached the code that I been using working on. The hardware used are NI 6013 & NI6723, together with two BNC-2110 as input and output. 

Thanks & Regards,

George

Hi,

first of all, if you want to have an application like this, a simple while loop will not be enough. You will need to use a state machine or producer-consumer pattern. You read about them here, you also have quite a few templates and examples in LabVIEW.

Another thing is that for finite generation, it would be better to use the "Finite Samples" sample mode (in the DAQmx Timing.vi configuration).

Hi,

Thanks for the help. I used state -machine and it worked.
