STeMwin GUI_CompactColor_16 problem

[liviana]

Posted on March 10, 2014 at 06:44

Hello! In order to show display in specific LCD like SSD1298, I must configure GUIDRV_CompactColor_16 according tohttp://www.segger.com/guidrv_compactcolor_html. I have made the LCDConfig.c, GUIDRV_CompactColor_c, andGUIDRV_CompactColor_h. But when I tried to debug, it came to hardfault handler, after executing

GUI_DEVICE_CreateAndLink(DISPLAY_DRIVER, COLOR_CONVERSION, 0, 0).

May I ask for explanation? Thank you very much. Here is the code of LCDConfig.c

#include ''GUI.h''
#include ''LCDConf_CompactColor_h''
#include ''GUIDRV_CompactColor_h''
#include ''LCDConf.h''
