emWin Graphic Library + PSoC3 (ERROR L127: UNRESOLVED EXTERNAL SYMBOL)

[Anonymous]

Hi guys,

Maybe you can help me.

After including this library in my project on PSoC3, happend such error during the bilding.

In project i have only GraphicLCDIntf_1.

I made all steps discribed in user guide for this library.

But after bilding had:

   

*** ERROR L127: UNRESOLVED EXTERNAL SYMBOL
SYMBOL: GUI_X_Config
MODULE: ..\LinkLibrary\PSoC3\Keil_PK51\emWinnosnts.lib (GUI_CORE)
Program Size: data=11.0 xdata=1704 const=493 code=3317
The command 'LX51.exe' failed with exit code '2'.

It looks like you are missing a .h-file in your project. Start a search through all files for the missing external symbol to get a feeling where you missed something.

Solution - to add in project:

   

/*********************************************************************
*
* GUI_X_Config
*/
void GUI_X_Config(void) {
static U32 aMemory[GUI_NUMBYTES >> 2]; /* Memory block for emWin, 32bit aligned */
GUI_ALLOC_AssignMemory(aMemory, GUI_NUMBYTES & 0xFFFFFFFC); /* Assign it to emWin */
GUI_ALLOC_SetAvBlockSize(GUI_BLOCKSIZE); /* Set average memory block size */
}
