How can I use for next like PORTB.MYVARIABLE ???

[Homerclese]

Hello,

Following the thread above, the code below does not work unless the value of k is made a constant as in: SOUND PORTC.5,[115,120,113,118]. I have never been able to use a variable to steer outputs to a specific pin. Any ideas?

'sound on pin k port c

TRISC= %00000000
k var byte


start:
k=5
SOUND PORTC.0[k],[115,120,113,118]
GOTO START

You should be able to use:

sound x,[115,120,113,118]

Where is x is between 0-15 with PORTA.0 being 0 and PORTC.7 being 15.

WOOHOO!

Thanks, yes that works, but I have never seen it written that ports A and C are linked and addressed this way. So then, PortC.5 is 13? I never would have thought of this. Is that only for the sound command? What about the addressing for port B.
