tachometers?

[dimes1827]

Hi!

i want to simulate a simple drag racing tachometer in a labview 6 or maybe 7..

like when pressing the up arrow (being detected thru events), the RPM goes higher..

something like that..

do i need an equation for this for gauges to act/behave like a real RPM meter (like using the

equation of an acceleration or any engine performance of a vehicle)?

or

i just have to use the detection of the time the UP arrow(for acceleration) is pressed and increment

the value for the gauge? and when the UP arrow is released the gauge should slow down gradually??

Thanks!

Well, I would suggest using an event structure to capture the arrow down keypress. Use the event on the VI panel called Key Repeat. From this you capture when the arrow is pressed and held down.

thanks! i haven't explored the Key repeat event..
