Hi, this is my implementation of the ending song of an anime serie of my childhood, please give a try...

Re posted to Projects - 'Music' area

A schematic would be a great addition to the code example

thanks for your contribution

[ivanrosales]

Sorry, the schematic is very simple, you can use a small speaker with a 10uF - 22uF electrolitic capacitor in series or you can use a piezoelectric directly connected between pin 2 and ground:

             PIC12F675
    10uF        ___
     \]      -o|°  |o-
 .---|]-------o|   |o-
 |   /]+     -o|   |o-    LED
 |           -o|___|o----->|--.
 |                            |
 |                            |
 |                            |
 | +  __ /|                   |

Thanks, your project has been updated. its here Really appreciate your taking time to add the scematic. It maybe simple, but many beginners really need that little bit of extra info.

ivanrosales,

Your project is too cool , so I had to give it a try. I made some changes to make it work with a PIC18F4550. Thank you.

Robert

[ivanrosales]

Nice implementation Robert!, the original melody's name is Ashita Ga Suki:



The PBP's Sound statement do all the trick, I just feed it with the result of the two lookup lists, one is for the PBP's Notes values an the other is for the duration (notes and silences).
In the "first pass" only the first 65 notes are played and then the whole 149.

I read all series of candy candy novel and I also watch this cartoon.candy is life loving and cheerful character.

Genial Ivan, gracias por el proyecto, me encanto volver a oir esa cancion, estoy preparandola para un pic 16f84a.
Supongo que como sos de mexico hablas español.
¿La cancion la copiaste a oido?, ¿o utilizaste alguna partitura para hacerlo?, estoy pensando en preparar otras melodias
