hi, i wonder if there is something wrong with this set of codes.
im doing a project and im incharge of the buzzer.

#include <p18f4520.h>
#include <pwm.h>
#include <timers.h>

#pragma config WDT = OFF


void main (void)
{
TRISB = 0;
PORTB = 0;

TRISAbits.TRISA4 = 1; // Button RA4 als Input
PORTAbits.RA4 = 0; // Button auf Null setzen


OpenPWM1(0xff); // set PWM
// set Timer2


while (1>0)
{
if(PORTAbits.RA4 == 0)
{
SetDCPWM1(90); //set_pwm_duty(90);
PORTBbits.RB3 = 1;
}
else
{
SetDCPWM1(20); //set_pwm_duty(20);
PORTBbits.RB0 = 1;
}

how about an explaination of what your code is supposed to do and what the problem is (error messages)


And next time you start a thread READ the BIG ORANGE BOX that says "BEFORE YOU POST" located directly in your face when you make a new post, especially take note to the part that says :"Give your topic a descriptive title, NOT "Help" or "Plz Help Me" or "I'm a noob"

and number 3.....but i'll let you read that one.

Please use the code tags, it makes your code much more readable. Also, if you're doing a buzzer, couldn't you just output the \a escape (which to my rememberence makes a beep). I won't repeat what jjsaw5 has already said
