Hi guys. I made a .vi that generates an output signal and it reads in input. I could not change in real time, frequency and amplitude, in the sense that changing the values of these two quantities there were not changes. I must press stop and then i set the new values to get the desired changes. This is because I had not added a while loop. At the time that I included the while loop with regard to output it's ok. The problem is reading input. If through two cables i connect the output pins with the input pins of my card daq i can not display the signal that I'm creating and I do not understand where I'm wrong. I'm using LabView from two weeks and i are not very practical. I am sorry for my bad English. Thanks
