help with alarm code

you mean something like this???

char* msg;

Why ask me? What does the compiler say?

AWOL:

cos you maybe know where im mistaking but you want me to learn not that someone writes my code...

SimplePost.ino: In function 'void loop()':
SimplePost:50: error: cannot convert 'char (*)[9]' to 'char*' in assignment
SimplePost:55: error: cannot convert 'char (*)[9]' to 'char*' in assignment

char* msg;

Is that what you tried and got all those errors? It looks most correct for what you seem to be trying to do. It's a pointer. Initialize it to 0 just in case.

Next you need to see what code sits on the line number it whines about, if it still does. I suspect the error messages point to all the lines where you are trying to assign something to msg and that's what you tinker. I can't tell off the top of my head at this hour what's it supposed to read for what you are doing there. I assume you are trying to assign the other array pointers to the msg one, so do that.

It's only going to work if twitter.post(msg) accepted a char pointer. I can see it takes a const char pointer judging by the error message. Well, see what the compiler tells you anyways without making too many changes at once between each compilation.

Another thing, if you end up getting a whole bunch of text posted (all of the strings), you probably need a null ending character \0 at the end of the string of characters. Or maybe not, I forget as I rarely have to deal with char arrays in C these days. Can you find out and post your findings?

 *msg =& str1;

The type of "*msg" is "char", but you're trying to assign an address to it.
That's why the compiler is upset.

Edit: I'm behind the times.

I think I am too.
Perhaps we could have a code update.

i understand that but, how can assing the variable and not the address??

Why don't you post the current code?

"*msg" is what "msg" points to, which is a "char"; you cannot assign an address (another pointer) to a "char"

this is the code so

What's that?

Swtich (count)

Up to a point, people will be willing to help, but if you start just posting garbage that has been pointed out before, they'll get bored and drift away.

sorry for that i dindt save the last code mods...

}

 void alarm()
 {

 }

this is still bad assigned pointer, but i dont know how to assing a char pointer to a char variable, sorry for that

msg = str1; etc

ok that really helps me out,

now there its only one error

SimplePost.ino: In function 'void loop()':
SimplePost:84: error: invalid conversion from 'char' to 'const char*'
SimplePost:84: error: initializing argument 1 of 'bool Twitter::post(const char*)'

I don't have the Twitter library (nor do I intend getting it), so that one's up to you.
Enough clues have already been provided (see reply #47)

  if (LedState == HIGH)
  {
    LedState==LOW;

Time to start reading a basic C tutorial. Don't just thrash around posting whatever comes into your head.

Do some simple programs first. Get the hang of it. Trying to do Twitter in your first code is ridiculous.

    switch (count)
    { case 1:
    msg =& str1;
    count++;
    break;
    
    case 2:
    msg =& str2;
    count++;
    break;
    
    case 3:
    msg =& str3;
    count++;
    break;
    
    
    case 4:
    msg =& str4;
    count++;
    break;
    
    case 5:
    msg =& str5;
    count++;
    break;
    case 6:
    msg =& str6;
    count=0;
    break;
    }
     }

And read up on using arrays. Won't you get bored copying and pasting when you end up with 100 messages?

nick its not my first code, but i did have pratice for long so im kind stck here, that if sentence was proposed by someone on tne debounce thing, so im not used to that i ust leave it that way.....

so finaly have manage to get it work this its the code

#include <SPI.h> // needed in Arduino 0019 or later
