Hi, Mark
For your code can I lengthen or shorten it ?

I mean if I want the song longer and shorter.
What kind of delay can be used ?

thx

Hi,

My real goal is to play a song from PIC.
It could be MIDI or WAV but I think MIDI uses fewer memory than WAV.
So I decide to use MIDI rather than WAV.
(PIC has only 256K memory !! If I use W ...

I don't know what MIDI code inserted to CCS code be?
I know that MIDI is just a sound that compose of each note C, D, E, ... , B.
but when we hear MIDI ,why we think that song sounds quite good eve ...

ckielstra,

delay_ms(500);

This gives you a single sound of 25 seconds....

Why 25 sec
It is 0.5 sec, isn't it?

Mark,

The little test program that I posted should gen ...

Hi, Mark

I try to make my new simple program based on your code.
Here is my code

Hi, Mark

I made a little change to your code.
So I don't worry about pushing button.

InitTimer();

Here is the code that i recieved form Mark and i wanna change this code for 16f877.
but when i try to change, so many problems have occured.
pls give me some suggestion to convert that code for 16 ...

THANK YOU VERY VERY VERY MUCH Very Happy

how can i convert this code form HI_TECH PIC to CCS C ?

#include <pic.h>

#define TONE RB0

void InitTimer(void);
void delayms(unsigned char cnt);
void PlayNote( ...

Sorry I give a wrong information.
I used code loaded from website that you gave to me.
So I burnt PIC with ringtone.HEX from your website without changing anything.

thx

Hi Mark,

I tried your code (ringtone.HEX) with 16F877 but it doesn't work !!
I used Xtal = 20 MHz and connected pin33 (RB0) to C = 1 uF and to speaker then shorted it to gnd.
But when 5V was app ...

Hi,
I use PIC16F877. I want to play the song (*.mid) to the speaker and I know that PIC has PWM module that can play this song. But how to make it?

thank in advance

here is my code

#include <16F877.h>

#fuses HS, NOLVP, NOWDT, NOPROTECT
#use delay (clock=20000000)

#define use_portb_lcd
