Simple Pic coding question

JohnDSiviter
JohnDSiviter over 15 years ago

Ok in one of my header files I have:

 

#define Switch_Pin1     PORTBbits.RB0

 

What kind of variable is Switch_Pin? (for example if I want to send this into a function I need to declare it as the correct type), would I be right in assuming this is a signed char?

    Hi,

     

    Switch_Pin1 is not a variable. It is a definition. It means that the compiler will replace Switch_Pin1 with PORTBits.RB0 while compiling the code.

    Thanks Kocak, when I went to bed that night it dawned on me that I didnt need to pass the value as you could call it direct in the function, and as you say the compiler will just replace it, still always good to get confirmation.
