Playing wave sounds, change speed

Posted: Wed Jun 03, 2009 7:49 am

With the help of a script out of the library I made a working engine noise generator. Now I want to control the speed of it with the help of a PWM servo signal. How can I do this best without interrupting the sound ?

Code:

#include <18F1320.h>

#fuses INTRC_IO, NOWDT, NOPROTECT, BROWNOUT, PUT, MCLR
#use delay(clock = 8000000)

#include "pullc.c"

int delayval;

void main(){
int8 i;
int8 c;
int8 currentbit;

c = sound_data[i];

setup_oscillator(OSC_8MHZ|OSC_INTRC);
setup_adc(ADC_CLOCK_INTERNAL|ADC_TAD_MUL_0);

while(1)
{

for (i=0; i<sound_length; i++){
c = sound_data[i];

for (currentbit = 0; currentbit < 8; currentbit++){

if( bit_test(c,currentbit) ){
output_high(pin_b3);
}
else{
output_low(pin_b3);
}

delay_us(delayval);

}
}
}
}

As you see, I have to change the delayval.
