hi , as we know that to use a particular pin of a port we use :

#define rs portd.f2 (in mikroc compiler )

i want to know that wether it is possible to use a function to have same functionality ,
i want to make a function in which , any port and any pin can be configured by user)i.e

something like this :
lcd(&portc, 2 , 3, 4) in which i can use any pins for rs , rw , en.

both the port and pins should be configurable.

is there some way of doing it because the in built libraries provided with mikroc compiler has this function , please tell me the details regarding this .

thanks.
 

Not familiar with that compiler but some micro controllers have their port bits memory mapped. Your function can then take a port and bit value and calculate the memory mapped port bit. Another way is something like this:

function(port_bit)// eg bit 18 will be in port 3
{
char portnum;
portnum = port_bit / 8; // work out which port
port_bit = port_bit % 8; // get bit number
switch(portnum)
{
case 0:
Port0 = Port0 & ~ port_bit;
Port0 = Port0 | port_bit;
....... do a case statement for each port. replace Port0 with actual port address
