"Select Case" Help

[Darrel Taylor]

I know this doesn't answer your question.
But perhaps all you need is ...

    PORTC = DCD Voltage.HighByte
    PAUSE 100

bmsherma, Try this...

SELECT CASE VOLTAGE

CASE < 257
PORTC = %0001

CASE < 513
PORTC = %0010

CASE < 769
PORTC = %0100

CASE < 1024
PORTC = %1000

END SELECT
Pause 100

I use this construct when determining groups of numbers. You start with the smallest and move up to the largest.

Thanks everyone for the advice.

Dave P, your idea seems to work. However what if I want to isolate the low range OR the high range. I'm essentially trying to put logical operators in my case statement.

Case is < 256 OR is > 768
PORTC = %0001

Case Else
PORTC = %1000

Can I write that first Case statement with the OR term?

Or would I have to do this:

Case is < 256
PORTC = %0001
Case is > 768
PORTC = %0001
Case else
PORTC = %1000

Is there no way to use logical operators in Case Statements in PICBasicPRO??!

bmsherma, The second way you have it is the way I would do the construct..

NO!, logical operators are NOT allowed in Case statements.

Thanks everyone for the help!!

This forum is GREAT

Hi,

With a very, very very little Trickery ... I think it makes it.

IF ( Voltage.8 ^ Voltage.9 ) THEN 

   PORTC = 1

ELSE

   PORTC = 8

ENDIF
