sound on a pic?

[Trevor]

I'm interested in outputting sound... is there anyway that I can program a PIC to do this?

Thanks

You should use PicList as a resource for Pic ideas.
Here is their page for audio. Look at the link
that goes to picsound.htm. It appears to have a lot of info.
<a href="http://www.piclist.com/techref/microchip/io/audio.htm" TARGET="_blank">http://www.piclist.com/techref/microchip/io/audio.htm</a>

You could also use the Search function of this board.
Search for the word "music".

I have been particularly impressed with this approach:

I read about Black Roman's method to generate sound. The algorithm seems working. However he wrote the code in asembly language, RETLW "0101 0101" means put the bits into accumulator w.

My question is: how to put the bits array into C program?

I once knew someone progam a beep by calculatin sinewave value when he started and using 8 bits to output numerical values, he then chucked the binary signal through a DAC and ended up with a perfect whistle.

doesn't let you make complex sounds though.

you could use the ADC to sample values fed in from a microphone them play them back.

See the example EX_TONES.C

This example plays the song "Happy Birthday."
