So according to you are saying, the user will be hearing the blood vessel then will input the moment to measure the max pressure, then input again the moment to measure the minimun pressure. Is that it ?
At each of those two inputs your program will read the pressure transducer signal. Is that it ?
In this case you can read the analog input using a buffered contiuous acquisition and at the same time (in the loop) keep reading a keyboard input (or any other input) as you detect the input, then you will get the data form analog input and place in a digital indicator.
Thanks ROtake, think that's the solution for blood pressure sorted, just need to find the time to actually do it!
As for blood pressure I have a TTL square signal being input (the one I similuted with a square wave). Can I use a counter to calculate the amount of times it switches level over a predefined time period? What tools/structure would I be using for that?
Just a quick update on how I'm getting on with simulating a sine wave for the blood pressure (again sorry for big pic )
This is the signal I'll have to select two amplitudes from (when the user clicks a button) although the 'Tone Measurement' tool doesn't seem to be working correctly.. I've kinda hit a brick wall here.
Any and all help appreciated!!
I believe this is more of a LabVIEW issue rather than Life Science, so I moved the thread to
Apologies for the poor forum etiquette although I couldn't find an option to delete this thread or
to move it. As for the project I'm currently learning about queues and ways of modularising the
tasks. Also trying to get to grips with using counting functions of my DAQ card.
I have a meeting with a technician in my university this week who deals with all the LabVIEW
here; hopefully be able to make some good progress then.
