Hello,

I just added your code to a test project and it compiled first time.

Can you please post the full output from the compile

Also confirm or email your full program code. Email to info[at]visualmicro.com

struct S{
     byte C;
     byte V;
     unsigned long d;
     unsigned long t;
};

void State(S s);

void setup()
{
}

void loop()
{
}
{ 

Thanks

Hi,

With your code I get errors in arduino 1.0.3 as well as Visual Studio

sketch_mar20a:4: error: variable or field 'State' declared void
sketch_mar20a:4: error: 'S' was not declared in this scope
sketch_mar20a.ino: In function 'void State(S)':
sketch_mar20a.ino:23: warning: array subscript has type 'char'
sketch_mar20a.ino:24: warning: array subscript has type 'char' 

Can you please tell me which version of the arduino ide you are using so that I can see it work.

Thanks

Thanks. I have found the problem and will resolve for the next release. You can probably workaround if required.

The problem is that Visual Micro is not detecting that you have added a prototype for

void State(S stat); 

. By adding your own prototype you elect exactly where in the code the prototype should be placed. In this case your prototype uses a custom data type defined earlier in the same code file. 

Normally Arduino prototypes are placed above the code which is what vm is trying to do but because your prototype uses the custom data type this causes the error S is not declared.

The workaround is to place your custom type definitions in a .h instead of in the .pde or .ino
