i m using 1 counter so how timer overflow can be avoided?

[PrashantS]

for my application to measure the time duration using hardware counter, i m using 6602 -32bit 8counter card.

i have to use only 1 counter to measure the time duration, but with 32bit counter i can count 216ms time duration, after that overflow will be started. with second counter i can avoid it easily, but i dont have to use 2 counter so, how programtically i can do that........

Kidnly guide me on that...

waiting for ur reply.

Hi Prashant,

when you don't want to use a second (HW) counter you should count the overflows in software...

[PrashantS]

but it is the requirement bcoz other counter is already engaged so i don't have any unused counter .......i want to use some software logic to avoid overflow.

[PrashantS]

so how i can do it with software.....if have any sample VI...than please share

Hi Prashant,

"if have any sample VI"

No, don't have.

but:

- IF "overflow occured" THEN count++

- "overflow occured" when actual count < previous count (assuming you always count up)
