是否可以从LabVIEW中的同一DAQ通道获取NI正交编码器的角位置和边沿计数？

Question

I tried to run the code below, but it doesn't let me select the same DAQ channel for both readings, despite the fact they should be taken from the same DAQ channel/encoder. Any suggestions would be welcome.

Answer 1

You can use the same input terminal to perform both measurements, but you cannot use the same counter to do so. I cannot see the values for your Counter(s) IO Controls, but I suspect they are requesting the driver use the same counter to do two different things.

Try using two counters like this instead. See how PFI8 is used as the input terminal for both tasks:
