There are many hits. Look at some with sample code:

I don't have the PCD compiler so I can't give any more help than this.

Fistly Thanks My Brother...


Secondly I use CCS PCWHD version 4.084...

compiler does not give an error and produce a hex code...

I put in to hex code... there is no PWM pulse...

What can I do????

My Code is here...


Code:

#include <30f4011.h>
#device ADC=10
#fuses XT_PLL16,NOWDT,NOPROTECT
#use delay(clock=7372800)


void main() {

 set_tris_e(0b000000000);
 output_e(0b000000000);
 

setup_timer2(TMR_EXTERNAL|TMR_DIV_BY_1);


//setup_timer4(TMR_32_BIT); //use get_timer45() to get the timer value



//setup_motor_pwm(pwm,options, timebase);
//setup_motor_pwm(pwm,options,prescale,postscale,timebase)

setup_motor_pwm(0,MPWM_FREE_RUN, 255);
set_motor_pwm_duty(0,1,10);


setup_motor_pwm(1,MPWM_FREE_RUN, 255);
set_motor_pwm_duty(1,1,55);

setup_motor_pwm(2,MPWM_FREE_RUN, 255);
set_motor_pwm_duty(2,1,180);






while(1)
{

} //while


} //main
