Hi,

I need to calculate a time elapsed for fft calculation. My doubt is when i call start timer function controller will execute a timer untill timer period then come back to main function or else does it initiate the timer and come back to the main.

conisder-->

main{

----

-----

timer_init();

fft_process();

------

}

void timer_init(void)

{

----

}

voif fft_process(void)

{

----

-----

}

Hi Shankar hiregadad,

The user will set the time period value in the form of a 64-bit timer period register through PRD12 and PRD34.

When the timer is enabled, the timer counter starts incrementing by 1 at every timer input clock cycle.

When the timer counter matches the timer period ( the one which is set through the PRD12 and PRD34) , a maskable timer interrupt (TINT12) and a timer EDMA (TEVT12) are generated.

You can utilize the timer interrupt where ever you want in your source code.

For more information on the timer, please refer to the timer demo example enclosed in the C6748 starterware package.
