Hey foks,
New to the board and LabVIEW software.
I'm currently working on a project that will essentially be used as an exercise device on a rowing machine(http://en.wikipedia.org/wiki/Indoor_rower). I will be using Vernier SensorDAQ as my data acquisition device with the following two sensors:
accelerometer: http://www.vernier.com/probes/acc-group.html
Hand grip heart rate sensor: http://www.vernier.com/probes/hgh-bta.html
What I would like to have is a VI that will acquire and process data in real time. The end goal is to be able to have have a beats per minute readout of one's heart rate, and a graph of one's distance. This data will be displayed to the user as he/she works out. Also the data will be saved for each workout and futher analysis will be available to the user post workout, such as calculating averages, min,max of HR and length traveled.
For the accelerometer I've decided to use a preinstalled subvi http://zone.ni.com/devzone/cda/tut/p/id/4989, called Integration SVT.vi, which essentially performs numerical integration on data to give velocity and distance from acceleration data.
For the hand grip sensor, I've tried to use labviews waveform peak detection VI. The hand grip HR sensor outputs a 3V pulse everytime a HR is detected. So I'm trying to convert these pulses into an actual beats per minute, that can be displayed on the front pannel.
I'm having issues getting this to run in real time. I have attached the VI's.
Thank you ahead of time for your responses.
