Hi
Anybody can create a pwm and reversed pwm also with 18f4580 chip
one time runs ones not a same time same pwm and reversed pwm.
Sorry for bad english.

Code:

//ECCP1CON EPWM1M1 EPWM1M0 EDC1B1 EDC1B0 - ECCP1M3 ECCP1M2 ECCP1M1 ECCP1M0
ECCP1CON = 0x51; // 0x51 Enable Pulse Steering on P1C(RC3)
ECCP1DEL = 0x80;
//ECCP1AS = 0x00;
CCP1CON = 0x00;
CCPR1L = 0x0C;

void yon_ver(int8 yonun){
if (yonun == 2){
// setup_ccp1(CCP_PWM|CCP_PULSE_STEERING_SYNC|CCP_PULSE_STEERING_A);
setup_ccp1(CCP_PWM | CCP_PWM_FULL_BRIDGE_REV);
}
if (yonun == 4){
// setup_ccp1(CCP_PWM|CCP_PULSE_STEERING_SYNC|CCP_PULSE_STEERING_B);
setup_ccp1(CCP_PWM | CCP_PWM_FULL_BRIDGE);
}
}

I load 18f45k80 program but did not worked.
