help in PWM change Code

hi every one
=============
I wrote this program sothat i can change pulse-width but i think there is an error as it doesn't work as it should.
i'm using Microc pro Compiler .
so can anyone help me.
===================================
here is the code:

hi!

try this:


sbit speed_I at RB0_bit;
sbit speed_D at RB1_bit;
sbit speed_C at RB2_bit;

unsigned short A, const_duty;

#define delay delay_ms(50)

void Pic_Init(){
trisb=255;
trisd=0;
portd=0;
trisc=0;
portc=0;
pwm1_init(10000);
}

void main() {
Pic_Init();
const_duty=127;
PWM1_Start();
current_duty=0;
pwm1_set_duty(current_duty);
while(1){
if(speed_I==1){
delay;
current_duty++;
pwm1_set_duty(current_duty);
if(current_duty==241){
current_duty=240;
pwm1_set_duty(current_duty);
}
}
if(speed_D==1){
delay;
current_duty--;
pwm1_set_duty(current_duty);
if(current_duty==15){
current_duty=16;
pwm1_set_duty(current_duty);
}


}
if(speed_C==1){
delay;
pwm1_set_duty(const_duty);
}
delay_ms(5);
}

thanks pmar_kpj for help

the program now run very well.

but if i want to increase the period at which the pulse-width change since i press the increase button, i.e. when i press pushbutton the pulse width become full after short time so if i want to increase this time i have to increase delay time of ( delay; ) . Is that right?

hi!

if change the "#define delay delay_ms(50)" with "#define delay delay_ms(500)" you increase the period with 2 units per seconds! now with delay_ms(50) you increase with 20 units!
