Hello everyone,
I have 2 frequencies. I want to determine its phase difference and want to check who is leading or lagging among both. For that, I am using PCI6602 NI Card with NIDAQmx driver and writing a code in c language. I have created two tasks and two counter channels for both the counters. I am counting pulses with the help of counters within certain time and then comparing its count value. But it is not giving proper output(eg. if I have frequency A and frequency B as input then output is sometimes 'A is leading' and sometimes 'B is leading') as I am unable to start both counters at the same time. How can I start both counters at the same time? Or Is there any other solution to determine who is leading among two frequencies?
Thank You.
