count for 10 seconds

I am begginer in PIC. I am doing it wrong. I know.

I am inputing this pulse train in figure in 16F... uC microcontroller.
Can you post exact code for a variable in assembly which holds the counts of how many pulses where detected within 10seconds.
Pass it then to another variable by overwriting it.

Afterwards to reset itself and count again for 10 seconds more. Loop.
I am very sorry to ask this simple question but thank you a lot.
 

Re: count for 10 seconds

1)Please tell me the speed your pic is running at.
2)Are you using tmr0 for anything in your prog.
3)Which port-pin is reading the pulse-train.

Cheers

HI,

What is the max. no. of pulses you want to measure during this period (10s) ?

hello Phinx. I dont know nr. of max pulses. A ballpark figure could be 2000.
Thank you.

Hello Raticus
1)Please tell me the speed your pic is running at.
3MHz

2)Are you using tmr0 for anything in your prog.
Not now.

3)Which port-pin is reading the pulse-train.
Right now I have all pins available

Thank you. Thanks a lot

Hi Djali

When you say 3Mhz is that your xtal freq. or is it 12Mhz xtal/4?

I will do the code for you.
