mikroC pic18f45k22 PWM

[Karolina_1]

hi, everyone. i am trying to control PWM modulation. But i am having some errors. I am using mikroC compiler and pic18f45k22. my code is given below can u possibly help. pleaseee.

void InitMain() {
PORTB = 0; // set PORTB to 0
TRISB = 0xF0; // designate PORTB pins as output
PORTC = 0; // set PORTC to 0
TRISC = 0xFF; // designate PORTC pins as output
Pwm1_Init(5000); // Initialize PWM1 module at 5KHz
PWM2_Init(5000); // Initialize PWM2 module at 5KHz

}

void main(){
InitMain();
PWM2_start();
while (1) { // endless loop

// 100% duty cycle: duty ratio can be calculated as (Percent*255)/100.
PWM2_Set_Duty(255); // Change the duty cycle
delay_ms(3000); //3 seconds delay

// 80% duty cycle
PWM2_Set_Duty(204); // Change the duty cycle
delay_ms(3000); //3 seconds delay

// 50% duty cycle
PWM2_Set_Duty(127); // Change the duty cycle
delay_ms(3000); //3 seconds delay

// 30% duty cycle
PWM2_Set_Duty(76); // Change the duty cycle
delay_ms(3000); //3 seconds delay

// 10% duty cycle
PWM2_Set_Duty(25); // Change the duty cycle
delay_ms(3000); //3 seconds delay

}

}

Welcome to the forum

Your code is OK, so maybe the problem is with configuration bits or hardware.

Project attached with working configuration assuming 8MHz crystal used. If this does not work, then maybe tell us more about your hardware setup.

Hi,

@hexreader thanks for helping our new users.

@Karolina_1 do you use EasyPIC7 board?
