thanks guys for all the help I got the facts of dspic staright now=20

but my only problem is how do i make my dspic do this=20

so if i sense the 12v Battery voltage from the analog input it will covert
the volatge to Digital=20
As the Duty Cycle will be the Function of the Input Volatge and voltage
reference(ie 12 V ).
I have to set this Duty Cycle Value to the PWM pin.. I need a formula or
some hints to write this algorithim
HElp please!!
