using the usb 9171 chassis and a ni-9411 module and Labview 2012
I have one reflective optical reader wired to the 9411.
this is mounted to the side of a conveyor bed to detect boxes passing by
I've been trying to setup a VI to count the number of boxes that pass by the optical reader (that part is the easy part) but to also give me a gage that tells me boxes per minute (which could be as low as 1 box passes by per minute or up to 60 boxes per minute)
any help??
