more Arduino silliness.

phoenixcomm

As a C programmer and learning Java,  I like to keep things VERY SIMPLE!!!

so normally I would have my file pins.h which would include a bunch of #defines like RST_1 13, etc. This now keeps me sane when trying to use it and stops me from wondering if is it this pin or that pin. (for amplification please see it below.  

So in the same header file I also want my pinMode statements which now can use my mnemonics rather than the stupid pin number.  this now is hitting close to 20-30 lines. 

#define RST_1 13
#define RST_1 12
pinMode(RST_1, OUTPUT);
pinMode(RST_2, OUTPUT);
BUT THE IDE tosses errors like  error: expected constructor, destructor, or type conversion before '(' token pinMode (RST_1, OUTPUT);

  • Ntewinkel is right.  Another way of looking at it, depending upon where in your C file you include that header, is you are trying to run code outside of a function, whether that is setup(), loop(), main(), anoFunction().  You can put code in an include file, along with the pin definitions as long as the include statement is placed inside a function.  HOWEVER, you must be aware of the ordering of code when the compiler processes all this: if it finds a reference to RST_1 before it has been included it will throw an error.
