help with alarm code

its the pointer i need..

What does that point to? Without making it point somewhere, you can't store data at the pointed to location.

char* msg

Except msg doesn't point to anything. If it was written like this:

 char msg[20]

msg now points to a char that has 19 additional slots available for use.

ok, i have made some crrections but, still IDE says expected initializer before 'if'

This is STILL wrong.

void setup()
{
  digitalWrite(2, HIGH);
  attachInterrupt(0, alarm, RISING);
  
  delay(1000);
  Ethernet.begin(mac);
  // or you can use DHCP for autoomatic IP address configuration.

void loop()

Curly braces are NOT optional and not wherever the heck you feel like putting them.

The compiler is right. You DO have stuff before the if statement that doesn't belong there.

y see that mistake sorry if i didnt see it.....

and if i just call msg as an char pointer and not an array????

like char *msg;

still the compiler says im wrong in the if funtion

What do you see as the first thing after "void loop ()"?
What do all correct sketches have that you do not?

Note also that LedState is not the same as ledState.
That may be important.

Also, "switch" needs to be spelled correctly, and not capitalised.

the void loop need to have an open brace.....

now that problem has clear, and the main problem now its that im using and incorrect call of the pointers

Really?

There was a comment earlier about braces being in the right places, and matching.

This is also important.

yes now the main problem its the pointer

yes now the main problem its the pointer

Don't hold back - feel free to share.

this are tyhe errors the compilers shows

"msg"" is a "char", not a "char" pointer.

you mean something like this???

char* msg;

Why ask me? What does the compiler say?

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

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??
