[HELP] Anyone know how to make sound/noise?

I have a PIC16F877, and need to know a program on how to make a beeping nose when a certain parameter is met.

The code can be in assembly or C.

Thanx!

You can just connect one of the output pins to a beeper and send 1kHz (or more) bursts. To do that, just set that output pin high, wait 1 uS, then set it low, wait another 1uS. Do this for some time (1 second), and you'll have a 1-second high-pitched noise.

If you don't know how to write delays in PICs, then post here again. Include the operation frequency of your PIC and a free pin (that can be used as output).

Dont you mean 1mS ?

1uS would give 1Mhz. A bit high to be audible.

i think he meant 500uS :lol: 1mS between toggles would only give you 500Hz (2 mS per cycle)
