Same code in different Pins

[keithdoxey]

Then you would change the PORTL and or PORTH assignments in the .bas file for the chip you are using.

PORTL and PORTH determine which ports are used for "Pin Numbers".
PORTL is 0-7
PORTH is 8-15

Hi Darrel,

I have looked in the .bas file for the 18F452 and located the following code

PORTL   VAR     PORTB
PORTH   VAR     PORTC
TRISL   VAR     TRISB
TRISH   VAR     TRISC

Would I be correct in assuming that you also have to "adjust" the TRISL and TRISH aliases as well?

I take it that the ports dont have to be consecutive so that I could put

PORTL   VAR     PORTB
PORTH   VAR     PORTD
TRISL   VAR     TRISB
TRISH   VAR     TRISD

Which would give me 0-7 = PortB.0-PortB.7 and 8-15 = PortD.0-PortD.7

If so that greatly simplifies something I am trying to impliment. The reason I want to change PORTH from C to D is that I need to use the USART which is on C6 and C7 so that would only give me 14 useable pins.


DOH !!!!

Thatll teach me not to make sure I have a newly refreshed view of a thread before I post a reply !!!!
