HI!!
Can you help us please with the following problem:
We made a PWM configuration (PIC18f452) to drive two motors using the CCP1CON and CCP2CON registers. It is the program code:
void Configuracion_PWM(void)
{
PR2=0xFF;
CCP1CONbits.DC1B1=DUTY_PWM1bits.BIT1;
CCP1CONbits.DC1B0=DUTY_PWM1bits.BIT0;
CCPR1L=DUTY_PWM1>>2; // Config. duty cicle (MSB) PWM1
CCP2CONbits.DC2B1=DUTY_PWM2bits.BIT1;
CCP2CONbits.DC2B0=DUTY_PWM2bits.BIT0;
CCPR2L=DUTY_PWM2>>2; // Config. duty cicle (MSB) PWM2
TRISCbits.TRISC2=0;
TRISCbits.TRISC1=0;
TRISBbits.TRISB4=0;
TRISBbits.TRISB5=0;
T2CONbits.TMR2ON=1;
T2CONbits.T2CKPS1=1;
T2CONbits.T2CKPS0=1;
CCP1CONbits.CCP1M3=1;
CCP1CONbits.CCP1M2=1;
CCP1CONbits.CCP1M1=0;
CCP1CONbits.CCP1M0=0;
CCP2CONbits.CCP2M3=1;
CCP2CONbits.CCP2M2=1;
CCP2CONbits.CCP2M1=0;
CCP2CONbits.CCP2M0=0;
}
This program works very well, but we have to put it into the FREERTOS, so the problem is that both of them are using the same register CCPCON1.
Thanks so much for your help. We´ll waiting your best answer.
