    Write an Embedded C program for Generating PWM signal for DC motor.

    #include<pic18f458.h>

    void main(void)
    {

    TRISCbits.RC2 = 0; // 00101100 to Select PWM mode; Duty cycle LSB


    CCP1CONbits.CCP1M = 0b1100; //CCP1CON<4:5> = <1:1>

    TMR2ON = 0;
    while(1)
    {

    PR2 = 74;
    CCPR1L = 18;
    TMR2ON = 1;
    }
    }
