Subroutine Question

GAF

Hi, I have worked with the Basic Stamp for a few years now and have recently started to work with the SX chip utilizing SX/B.· The·program that I have been working on (attached) utilizes a 12-bit A/D (MAX 187) to read a analog voltage and display the scaled result on a 16x2 LCD in 4-bit Mode.· I do have this program operating, however, I would like to make some improvements.· In particular I have trouble making two subroutines work by first setting them up in the Subroutine Declarations.
It seems that I am only sending 1 byte to the sub, but when try to complie it I get
"Invalid Number of Parameters".· The program will operate if I use "gosub" prior to these subs.· Any help on the subject would be appreciated.

Just a few bobbles -- you should use PIN instead of VAR for IO pins (that was causing an error in your listing). Both LCDCMD and LCDOUT take one parameter so the SUB declarations were updated.

I was just looking at some of the example programs in the SX/B Help files.· Most, if not all of these use VAR for their I/O pins instead of the PIN directive.··What is the·correct way of doing this?

GAF,
· The help file is in the process of being updated. I/O pins should be defined with PIN.
· Such as:
· ··LED···· PIN RA.0 OUTPUT
··· Switch PIN RA.1 INPUT PULLUP

The help file does include comments on the use of PIN as well.
