Hello List!,
    I don`t know if it is simple problem or not ...anyway ...

Target Chip : PIC16F877.
A/D  : 10 bits.
programming language : PICC.

  the problem is that how to calculate the actual value of the A/D readings,
for example :
 I am reading the voltage on a specific pin by using the A/D(10 bits) ,but
the value in these 10 bits are not the actual value of the applied voltage
so who can I converet it to the real value,

A/D(10 bits) value                         voltage

.......................                                        ? I don`t
know how to get the values here
......................                                         ?
.......................                                        ?
......................                                         ?

thanx in advance,
