Error calling functions in new (own) source file

Hi Guys,

CCS v 6.1.3.0034 (compiler version = TI v15.12.1.LTS)

TMS320F28075

control Suite v 3.4.0

I want a separate header and source file where I will write all the variables and functions for my project. The main.c file has only the initializations of Sigma delta and ePWM. I started by creating new files: myExample.h and myExample.c. And in myExample.c I included the following lines :

#include "myExample.h"
#include "F28x_Project.h"     // Device Headerfile and Examples Include File

    GPIO_SetupPinMux(31, GPIO_MUX_CPU1, 0);
    GPIO_SetupPinOptions(31, GPIO_OUTPUT, GPIO_PUSHPULL);

I included the "F28x_Project.h" because it has all the headers. Now I get the following errors:

>> Compilation failure

subdir_rules.mk:84: recipe for target 'myExample.obj' failed

"../myExample.c", line 11: error #80: expected a type specifier

"../myExample.c", line 11: warning #78-D: this declaration has no storage class or type specifier

8 errors detected in the compilation of "../myExample.c".

gmake: *** [myExample.obj] Error 1

gmake: Target 'all' not remade because of errors.

Please tell me what am I doing wrong here?

Thank You.

Prakash,

It doesn't look like there are any functions within your .c file. Only calls to other functions?

I suggest examining some of the examples within controlSUITE device_support.

Thanks Lori.
My bad, I did not think of it. Now it works.

void functionONE (void)
 {
 GPIO_SetupPinMux(31, GPIO_MUX_CPU1, 0);
 GPIO_SetupPinOptions(31, GPIO_OUTPUT, GPIO_PUSHPULL);
 }
