How do i make a clock/timer that can be reset to zero?

[botenb]

I need to make this clock/timer to run my control off of. To be more detailed I need to ouput a steadily increasing voltage slowly over a period of time. I have my DAQ assist set up to output a voltage to my device but i can't figure out how to make the timer/clock correctly.

Can you post the code that you're trying to use?  Have you looked at the Ramp VIs?  (Search the palettes for Ramp)

Well I'm pretty new to using labview and the only version I have available is 7.1. If you can could you show me how to make a working clock/timer that's where I need the most assistance. I need to be able to set an end time and reset to 0 afterward.

there was a brief discussion in the Minneapolis LabVIEW users group where such a timer.vi was discussed

It seems you simply want to update the ramp at a constant dt, why would you need to reset anything?

There are two main ways to do this:

software timed: use a loop with a given delay and write single points to the output.

hardware timed: setup timing for your task and send the entire ramp to the hardware. It will do the rest. No extra code needed.
