The project is to write a program that

$1-$increase or decreasea DC moto speed using potentiometer.

$2-$ display the motor speed on $27-$segments.

Fosc$=4$MHz

Potentiometer range $0$ to $5$ volt

Motor max voltage supply $=5$ voltage

i need the full code to put it in mplab pic$18$f$452$ and give me any calculation you do it
