Count edges with DAQ Assistant
- [Instructor] Since my USB 6001 only has one counter with the ability to count digital edges, I'll demonstrate how to do that using the DAQ Assistant Express VI. Starting from a blank VI I'll place a DAQ Assistant from the measurement IO DAQ MX palette, I'll configure it to acquire signals and select counter input, and I see several different options here for different types of counter measurements, but I'll choose edge count for this demonstration, and then select counter zero, which is the only counter on this device. The default settings here look good, the counter's going to count rising edges starting at zero, it'll count upwards, and it'll accept its input signal on PFI 0. To generate digital pulses for the counter I've connected a push button switch and resistor to the PFI 0 terminal as shown here, it's the same circuit I used in a previous video to generate a digital edge trigger. Back in the DAQ Assistant, I'll…
