Hello,

I am developing the code for my PIC32MK1024MCM project. I have already tested the code well and now I am only putting all the code modules into the final project (the code is not complete in this example yet, but the functionality is not the axis of interest here). For the first time in my life, I wanted to make it a little bit more professional and use separate source and header files for all the different module function declaration. However, I am clearly facing some kind of syntax problem, because I am getting errors in almost every line of the source file (I guess I have to include something in that source file, but I am not sure) Like I said, it is my very first time facing header and source files, so could you please help me, or at least hint me, what is it that I am missing so obviously? I want to thank you in advance.

main:

#include <xc.h>
#include <configuration_bits.c>

#include <toolchain_specifics.h>
#include <stddef.h>
#include <stdint.h>
#include <stdbool.h>
#include <stdlib.h>
#include "stdio.h"
#include <sys/attribs.h>

#include <analog_to_digital_conversion.h>

    void main(void) {
        
      
      
            while (1){

            }
            
        return (EXIT_FAILURE);
        
    }

I also tried including "definitions.h" at the top of the source file, but still, I am getting errors (depicted in the pictures)

 

Don't include a .c file. All .c files should be in the source file hierarchy of the project so the generated makefile and make can find the correct object and object definitions.


You should also stop possible Prevent Multiple and Circular Inclusion of Header Files. MPLAB X IDE will generate the defines for you if the file is created in the IDE.
