Other Parts Discussed in Thread: CONTROLSUITE

hi..

i have to make an integrator in f28335. The logic i hav to use is as follows:

out=0;

while(1)

{

out=out+k*dt;

}

Here i need dt- which is time difference. I may have many other codes also in between these codes. how can i get the time dt?

i'm using ccs4.

thanks in advance

regards,

Mahesh

Hi Manesh!

An integrator is LPF. Maybe FIR LPF will be a good solution for your issue

hi igor!

yeah.. i can use fir filter for this application, but my requirement is something more ...

pls suggest me some way to find 'dt' using some peripheral clock.

What is a particularity of your requirements if this will be no simple LPF? (If it is not commercial secret).

Hi Igor.

my requirement is very small. i just want to know the time taken for a loop to execute in my code.

Mahesh
