Programming Ultrasonic sensor HC-SR04

[kdm7]

Hi Dennis,

I think I dint convey my question properly. The trigger which I'm taking about is not the trigger input to the basic event counter. The ultrasonic sensor needs a 10us pulse for it to send a high at its echo pin. I just want the PFI0 pin to produce(send) a 10us pulse. For this, I need to know the usb 6008's clock frequency. (To know whether PFI0 can produce a 10us or not, as PFI0 acts as a counter). I could'nt find the clock frequency on the specs.

Hi kdm,

we all know what you're talking about…

READ MY LIPS: THE USB6008 CANNOT PRODUCE PULSES IN THE MICROSECOND RANGE!

Is it clear enough so you understand the meaning of this sentence by now?

- PFI0 is just an input for the USB6008. It will NEVER output any pulses…

- There are clock frequencies given in the specs, but they are irrelevant for you: 10kHz for AI, 150Hz (max, software-timed) for DIO…
