    hello..i really need help about to control the current going to dc project is to avoid the high peak current when initial dc motor start work.. but unlucky, i really lack of pic programing. i plan to use pwm to control the speed and the current going into dc motor .My question here..
    1) the value of ocsillator is actually give effect to the pwm?or it just make function to make the PIC work as without give anny effect to pwm?

    The osccilator makes the pic go. Effects on pwm are small and resolved in programming.
