Can some one please help me on this. Ive been at this for weeks now with out any joy. Im trying to synch my analog Inputs with my encoder input. I have tried everything. I have used the ai sample clock as the source for my encoder as stated in the tutorial for m series synch (http://zone.ni.com/devzone/cda/tut/p/id/3615). Have looked at all the examples and tried different trigger configurations with no succsess. My motor position data is approx 80ms ahead of my analog data every time. If i delay the encoder start by 80 ms they nearly line up but i want them to start at the same time. I am using labview 8.2 and a m series usb 6218 cheers

synch analog inputs with angular encoder

Hi Michael -

It's very difficult to troubleshoot your VI as you posted it. Could you please provide a simpler piece of code (consisting of only DAQmx functions, if possible) that exhibits the behavior of returning 0's in the first read?
