How do I get 3kHz signal?

--------------------------------------------------------------------------------

I am using PIC 16f887

I have a timer of 10ms .

I want to obtain 3Khz signal using this timer.

If anyone has an idea please let me know

Thank you

10ms means it overflowing at a rate of 100HZ. What kind of signal are you trying to create?

If it were to overflow 3k times a second, you'd need a period of 333.33333 usecs, not counting overhead.

I agree with you

Actually I need 3kHz signal for sound

I want to know if I can use the timer of 10 ms for getting that particular frequency

Thanks for your opinion

As wannabe just said, your timer is too SLOW. It sounds like you just want to copy paste code.

With a 8mhz osc
Take timer0 and set Prescale value 1:2
Preload TMR0L 106

And let it toggle a port pin on event
