Unions
PostPosted: Fri May 06, 2005 7:24 am     Reply with quote
It may seem trivial but I have searched the forum about unions and still have not solved my problem. With compiler version 3.224 I cannot compile any unions or maybe I am just coding them wrong. Here is test sample that I am missing somthing on. Any help would be appreciated.
Code:

#include <16f877a.h>
#DEVICE ADC=8
#fuses HS,NOLVP,NOWDT,PUT
#use delay (clock=20000000)

typedef union {

   int i[4];
   char letter[4];
   long test;
} maybe;

maybe.i[2] = 4;

maybe.letter = "a";

maybe.test = 5500;

main () {

}

Thanks,
Guest

Well I tried it and no success. Did you actually compile that Code? The actual code I am trying to use is:
Code:

#include <16f877a.h>
#DEVICE ADC=8
#fuses HS,NOLVP,NOWDT,PUT
#use delay (clock=20000000)

typedef union {

   int i[4];
   char letter[4];
   long test;
} maybe;

maybe question;

question.i[2] = 4;
question.letter[1] = "a";
question.test = 5500;

main () {
}

First, for a char use 'a' instead of "a".
Second, you have to make you assignments in a function not in the declaration!

Code:

#include <16f877a.h>
#DEVICE ADC=8
#fuses HS,NOLVP,NOWDT,PUT
#use delay (clock=20000000)

typedef union {

   int i[4];
   char letter[4];
   long test;
} maybe;

maybe question;


main () {
  question.i[2] = 4;
  question.letter[1] = 'a';
  question.test = 5500;

}
