The essential code on PIC12f683 could be:

Code:

setup_timer_0(RTCC_INTERNAL|RTCC_DIV_1);
setup_timer_1(T1_DISABLED);
setup_timer_2(T2_DIV_BY_4,24,1);

setup_ccp1(CCP_PWM);
setup_comparator(NC_NC);
setup_vref(FALSE);

setup_oscillator(OSC_4MHZ);

// program code...

set_pwm1_duty(value); // in code pwm setup

This is a 4Mhz internal clock with a 10Khz PWM output with 0-100 pwm step of resolution... but your was a too much general question! this is just a working example Smile

hope you can get some direction.
