STM32f107Vbt6 controller interfaced with 3.2 inch ILI9341 display by using ST emwin GUI .After the LCD_X_DisplayDriver() function ,the debugger entered into HardFault handler() while debugging.(SPI Interface).GUI_DispString("Hello World!") is not working

In GUI_Conf.c, allocated the memory size for GUI.And in LCD_Conf.c file, declared the size of display ,configured the flexcolor driver for ILI9341 controller.And aslo implemented the read and write function by using SPI. In order to resolve the Hardfaul handler(), I have changed the Stack and Heap size and also change the memory allocation for GUI. Is there any configuratio n need to be done?

Hello @Kanna​ ,

Please share the source code to check more the configuration and the behavior.

Did you called the GUI_Init() function and enabled the CRC module ?

GUI_Init() should be used to initialize the STemWin internal data structures and variables. And performs the initialization of the display by calling the function LCD_X_Config().

I advise you to have a look at the AN4323 Application note Getting started with STemWin Library.

Hi Imen,

Thanks for your response!!

Yes, I had called the GUI_Init() function and also enabled the CRC module.Based on that AN4323 Application Note, Driver files were ported into my application.Again I will look on it. Here I have shared the code.
