I'm sorry... I haven't understand the question..
Bad mistake. I'll be more careful.

Gabriel, anyway I should be able to see the first time it happens right? The problem was that I couldn't see that happening. Now after doing what I've mentioned in previous reply, I can see it happeni ...

Hello PCM Programmer... if I either add #int_rtcc routine or remove

setup_timer_0(RTCC_INTERNAL|RTCC_DIV_256);
enable_interrupts(INT_RTCC);

lines, the code works..

That was the problem I ...

Gabriel,
Thanks for the reply.
yeah, checking it inside isr is better. Anyway I don't get a 1Hz output signal..

When my program runs, at the beginning timer is set and when number of interrupts ...

I want to count seconds using timer1 of 16F877A. I used 4 as the prescaler. So the number of interrupts per second = 20000000/(4x4x65536).
To check whether this works, I wrote the following code.

...

Ok sir. Thank you very much.. Yes they know it. I'll get data from them and try to write the code. After writing that part and simulating, if it causes problems I hope you'll help me.

Thank you Mike Walne and Ttelmah.

Ttelmah, Our project is to count the number of people entering a room, display it in a lcd display. And control the fan speed according the temperature inside the ...

Thanks again. Smile

I had already done this part. Smile

Actually what I asked was how to begin that AC motor controlling part. Apologize for not being clear.
But I had kept following lines which were g ...

hello PCM programmer, My PIC is 16F877A and frequency is 20 MHz.
Thanks both PCM Programmer and Ttelmah.

I read the datasheet.
According to that what I finally decided was, to satisfy the minimu ...

I'm new to PIC programming.
Can someone please tell me what are the factors that I should be concerned about when setting ADC and timer clock inputs. I have given a project to complete but this is no ...
