Take time between two max values

[jocuma]

Hi people,

I have a problem and I have know idea how to solve...I need help.

The problem is that I want to take the time between two max values like in the graph you can see.

For example in the picture that I add

4,5 - 1,840 = 2,66

And put this value in the "Temps entre mostra".

This is that I want...

But this I think is very complicated because I don't know how to take the correctly time and do the substract...

thanks a lot,

Any solution?

Hi jocuma,

I've tried something and hope that helps u.

Just created two arrays of temp and voltage. First i'll get the voltage value when it's more a certain value and of that same index get the time value and store in shift register.

When i get the second value higher than the threshold, I will get the time and subtract from previous value.

Well,

temps = time no temperature.. 

I'm Catalan and maybe created some confuse things with the language Jaj...

Doesn't matter temps / time /tempearture, did u get the logic first??
In the example array i've provided, u should time = 1840-1770 = 70. which is what u need r8?

Yes,

I tried something like this....now I'm...try to tested the results

[jocuma]

It works but... for example

in the 17,990 - 17,910 =  0,08 or 18,010 - 18,000 = 0,010

this would be the correct time... :S 

I dont know if I explain good what I want..

[udka]

Yes, that's correct. for example, i've just taken some numbers. Good to know that it helped 🙂

[jocuma]

Uday it doesn't work good.

I pass my program ...It would be grateful if you can help me...

The program didn't substract good, because it substracts to 0 value and I want to substract the actual time from the last time...

Do you understand my problem?

srry for my english..

and thanks a lot,

Jocuma
