Need Help with DAQ in Labview

[Patra79]

Hi Dennis,

I tried to append the waveform like you had suggested with a for loop and I also initialized the shift register with a empty waveform but I end with the same thing because the empty waveform is not updating its value...which i don't know why.....kindly look into my VI and let me know the possible reason for it and how can I overcome this problem...

Thanks and regards,

Suresh

No, the shift register is in the wrong place.

Hi dennis,

I just ran the modified VI which gave but the for loop is not executing and returning the value 0 but rest of the program runs fine.

Thanks and regards,

Suresh

Sorry, the inner for loop is not executing because of the initally empty array. It's auto-indexing and a for loop will iterate to a count equal to the size of the smallest array. You could change it to not auto-index and wire a count to the N terminal since you know how many channels you are capturing. A couple of index array functions inside could be used.
