CODECOMPOSER: Undefined symbol

Hi everyone,

I have a simple following code:

Fullscreen

#include "device.h"
#include "driverlib.h"
void main(){
Device_init();
}
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

The function Device_init() is defined in "device.h", and I have included it.

 

Why I still receive the following error:

    Is it *defined* or *declared* in device.h?

    If it is only a prototype in device.h, you may need to make sure that the source file that contains your routine is in the search path.

    sorry for the confusion, it is declared in device.h

    Hello,

    Make sure that the proper include and library paths are set up in the Project Properties (you can refer to an example in C2000Ware for the device you're using). The Device_init function is defined in the device.c file, so if the function is not recognized that means you have not configured the project to include the proper driverlib source code.

    As a general recommendation, you should be creating projects based on the empty_project template for the F2837x/F2807x device in C2000Ware 5.01 (for other devices, you should be able to use the universal example which has the SysConfig Universal Project setup).
