Reloading registers

[Colin hughes]

In continues pulse traine mode you can update the pulse width and delay on the fly.

How do you do this in retriggerd pulse mode.

This can be done with the old 16 bit timers so why not with the 32 bit timers. This is very limiting

It sort of works but seem to update only after a second call.

Resetting the timmer everry time the delay or pulse width is change is not an option for me as it breaks our products.

To give you an idear.
counter1 open flow valve. (ok)
Conter2 close spill pulve, (presure increase)

reset counter1 to change delay ( Flow off) pressure increase Bang. No good.

Thanks

Hi Colin,

I found this example program on our Developer's Zone. Generating a Retriggerable Pulse with Changing Pulse Specifications Maybe this is just what you are looking for?

I hope this helps!

Hi Russell

Looks like it might help but the link does not work.

Thanks

Forgot to say I am not using Labview but Borland c++ builder.

Hi Russell

Found it.
I will look at it at work as we have Labview there.

I have tried using Switch Cycle before but found that on the first change nothing happend and on the second change the first value is used and so on. Perhaps I am doing something wrong so I will experiment a bit more.

When I first start the counter I start then as normal for rettrig pulse than change to using Switch Cycle.

Might stop me breaking Injectors or pipes (Diesel injectors test bench)

Thanks
