I have a question regarding the "proper" (i.e. cheaper in terms of system ressources, easier to read, etc) way of testing the first entry in while loop. One way would be by using a shift register another by detecting if the loop iteration is zero (see the exemples attached here). I am doing some calculations in this loop, typically 300 iterations or so.
Which way is better ? Are there other (simpler) waysofdoing this ?
thanks for the answers
concerning the express vi : for me the time_elapsed seems unavoidable !
