Bit of a port question!

[hooray]

Hey there, I'm using a PIC1846K20 for a project at the moment and I'd like to know, is there a way to call a specific pin on a I/O port without pointing to the specific name to it? I've got some code that works the way I want it to but its LOOOOONG, have a look for yourself:

void PortOutSetOn(unsigned short Port)
 {
	
	if (Port == 1)
	PORTDbits.RD0 = 1;
	if (Port == 2)
	PORTDbits.RD1 =1;
	if (Port == 3)
	PORTDbits.RD2 = 1;
	if (Port == 4)
	PORTDbits.RD3 =1;
	if (Port == 5)
	PORTDbits.RD4 = 1;
	if (Port == 6)
	PORTDbits.RD5 =1;
	if (Port == 7)
	PORTDbits.RD6 = 1;
	if (Port == 8)
	PORTDbits.RD7 =1;
 }

Port is bounded from 1 to 8 if you havent guessed so yeah, is there a way to assign the turning on of a specific PORTD bit to a corresponding value of Port, without affecting any of the other pins on PORTD?

thanks in advance!

You could use PORTD|=(1<<(Port-1));

Hmm, I seem to be getting some overflow from PORTD, I'll keep playing around with it.

nah thats not doing the trick, sorry. either im having some other things going on in the other functions i dont know about yet, or i may need to have a closer look at the operator

The code I posted does exactly the same as the routine you posted.

right, then im gonna have to dissect this thing into next week

 

[hooray]

I just forgot to initialise something!

It works now, thanks for the help Mike
