Hi,

Can you please help me to generate Bell Sound using PIC and CCS C compiler. I need a polyphonic like sound.

Thank you

Not a lot to go on, but how about:
PIC output pin driving a relay via transistor driver (or ULN2003).
Relay contacts used to replace the switch in a doorbell.

Meets your requirements, but probably not what you were really asking.
If you're more specific then you stand a better chance of getting the answer you want.
