Pin as variable?

[dream-]

Is there a way to set a Pin as a variable?

Something like:

...
myPin = PORTB.1

High myPin
Pause 1000
Low myPin

myPin = PORTA.0

High myPin
Pause 500
Low myPin
...

Using myPin VAR PORTB.1 is not good since I cannot define the variable several times. Am I missing something obvious?

Hi;

Yes;

like this;

LED   VAR PORTA.1

High led
pause 500
low led

Thank you for your response, but as I mention in my original post, that is not what I am looking for, since you cannot define the variable repeatedly in the program. If you look at my example I am assigning two different Pins to the same variable. Thank you anyway

Why do you want to use the same variable name for two different things?

I am not using the same variable for two different things.

I have a subroutine that sends a special signal through a pin, and I need to be able to control which PIN the signal is sent through.

So the easiest way would be to do something like:

myPin = PORTB.1
gosub SendSignal
...
myPin = PORTA.1
Gosub SendSignal
...
myPin = PORTA.0
Gosub SendSignal
...
SendSignal:
... 
HIGH myPin
(Do more stuff)
LOW myPin
Pause T
HIGH myPin
T = something
Pause T
Low myPin
(more stuff)
High myPin
Tf = T*something
Pause Tf
Low myPin
...
RETURN

Since the SendSignal routine is quite complex, I would like to implement it this way. I can't use a CASE SELECT either because everytime the routine has to do something with the pin, I would have to have a separate CASE block.

Any ideas?

myPin = PORTB.1
Read the state of the pin and stores the value to myPin.

HIGH myPin
Is for making a pin HIGH.

So the way you want to do it will not work.

The only way I see to do what you want is to use an IF/THEN/ELSE block with three condiitons or CASE SELECT with three conditions.
