New version GUIBuilder from Segger color setting

For set color operations

Old (5.28) example
GUI_SetBkColor(0x00361400);

New (5.40) example
GUI_SetBkColor(GUI_MAKE_COLOR(0x00361400));

CubeMX 4.25 & 4.26 GRAPHICS configuration MULTIBUF bug

If we create a graphics window for GRAPHICS configuration with GUIBuilder for file GUI_App.c

CreateWindow();



The CubeMX is creates function in file STemwin_wrapper.c



void GRAPHICS_Init(void)
{
/* Initialize the GUI */
GUI_Init();

//WM_MULTIBUF_Enable(1);
/* Enable the multi-buffering functionality */

/* Activate the use of memory device feature */
/* USER CODE BEGIN WM_SetCreateFlags */
//WM_SetCreateFlags(WM_CF_MEMDEV);
/* USER CODE END WM_SetCreateFlags */
}



If you delete comments

WM_MULTIBUF_Enable(1);
/* Enable the multi-buffering functionality */

/* Activate the use of memory device feature */
/* USER CODE BEGIN WM_SetCreateFlags */
WM_SetCreateFlags(WM_CF_MEMDEV);



after this, the graphical interface stops running !!!

(Attention!  After deleting comments and compiling, turn off and turn on the power)

The problem is solved by adding a line



WM_MULTIBUF_Enable(1);
/* Enable the multi-buffering functionality */

/* Activate the use of memory device feature */
/* USER CODE BEGIN WM_SetCreateFlags */
HAL_LTDC_ProgramLineEvent(&hltdc, 0); //!!!!!!!!!!!!!!!!!!!!!!!
WM_SetCreateFlags(WM_CF_MEMDEV);
/* USER CODE END WM_SetCreateFlags */



And everything works fine!



P.S.

If FREERTOS is used, it is necessary to eliminate one more bug
