Hi,
I want to use stemwin gui library with my stm32f429 board without any external ram for driving 320*240 tft LCD, so i will use mcu internal ram. when i use "GUI_DispString("Hello world!")" function , i can not see anything on the screen. For discovery board there is a external sdram and in "LCDConf.c" file the frame buffer is defined as :

                                               
           
 
            
           
#define LCD_LAYER0_FRAME_BUFFER  ((uint32_t)0xD0200000)
           

So, if this is the problem for my board ( i am not sure), what must this value be ? Any advise ?     ( when i use the value " 0x20000000 for buffer adress that is the mcu internal ram adress, the code crashes.)
