hi everybody, i have a problem with timing on my FPGA, i would like to acquire a signal at 400khz, and the analogique/digital converter( NI5731) is working at 40MS/s, so one period of my sinewave should be described by 100 points, but what i see ( picture attached) is that one periode is described with 23 points. So it seems like the analogic signal is not sampled at 40MS/s as it should be. Any help ? Thank you ! Regards Jean

Here you go !

Using FIFO is what you should do. But you should check "Timeout ?" like in the example to check if you are losing data or not.
