How to write port names into array ?

[CuriousOne]

Hello.

I have a code, where port names are assigned to specific variables, like this:

AC5 var PORTC.5
AC4 var PORTC.4
AC3 var PORTB.3 
AC2 var PORTB.1
AC1 var PORTB.5 

AR1 var PORTB.6
AR2 var PORTC.7
AR3 var PORTB.2 
AR4 var PORTB.0 
AR5 var PORTB.4 
AR6 var PORTB.7
AR7 var PORTC.6

I want to modify code in te way, to store this data into array, so I can read sequentally with FOR-NEXT. How should I add port names into array members?

Say my array name is ROW, code should look like:

ARRAYWRITE ROW, [what maxlength?, what label?]

There is good info here addressing your question, both better written and more correct than anything I may post. It explains how to read and write bits in bytes, bytes in words, bits in arrays, etc.

Thanks, but it does not answers.

In fact, another memeber there asks exact same question, but gets no answer.

Does this help?

Sure, this is way better, but still not exactly what I want. Since it utilizes loop and constant subroutine calls. I want to have defined the array in the beginning of the code, and access it as needed.

So are you looking to . . .
AC5 var PORTC.5
AC4 var PORTC.4
AC3 var PORTB.3
AC2 var PORTB.1
AC1 var PORTB.5

AC = %00010101
and then have the listed ports go high according to the declaration above?
If SO try AC = ~~%00010101

var byte LEDS[4] 'declare array with 4 members
LEDS[0]=3
LEDS[1]=8
LEDS[2]=12
LEDS[3]=9 ' put port numbers into array

FOR A=0 to 3 ' make increment
high leds[A] 'set high port number, stored in specific cell of LEDS array. could try high portb.0[leds[a]]
PAUSE 1000 'wait some time,
low LEDS[A] ' turn led off might be low leds[A]
PAUSE 1000
NEXT


see port indexing this forum just a few days ago or page 30 of pbp manual



you could also use lookup
