Posted on March 30, 2018 at 17:29Hello everyone,
I�m develop an application on a STM32F469 Discovery Board with StemWin Graphics on Keil MDK uVision 5.24.
The first tests worked well, but i get problems when i change to the CubeMX front end.
It's impossible to change widget content if GUI_Delays in the process are.
I will describe the develop steps at a very simple test program:
Step 1 on CubeMX 4.25
- New Project
- Choose Board: STM32F469 Discovery
- All Default Settings: Yes
- No Pin Clear
- PINOUT
- Disable FreeRTOS (otherwise i get errors. STemWin should work as single task. )
- Graphics /Stemwin: enable
- CONFIGURATION
- Graphics: Enable GUI Builder
- Execute GUI Builder, and make a Frame with 2 EditText Widgets
- Generate Code: Keil MDK 5
Step 2 on Keil MDK uVision 5.24
- Build
- Run is OK � GUI is on the Display
Step 3 on Keil MDK uVision 5.24
- Modify GUI Source �FramewinDLG�; Source Code is below. Run
- GUI is on the Display but no changes in the Widgets!
- Leds blinking -> Loop is running !
- ????
I would be very grateful if someone had a solution.
The CubeMX project file is attatched below.
Thanks!
�FramewinDLG� Source Code:
.

/*********************************************************************
*
* CreateFramewin
*/
&sharpinclude 'main.h'
WM_HWIN CreateFramewin(void);
WM_HWIN CreateFramewin(void) {
WM_HWIN hWin;
WM_HWIN hItem;
hWin = GUI_CreateDialogBox(_aDialogCreate, GUI_COUNTOF(_aDialogCreate), _cbDialog, WM_HBKWIN, 0, 0);
hItem = WM_GetDialogItem(hWin, ID_EDIT_1);
GUI_Exec();
while(1)
{
GUI_Delay(500);
EDIT_SetText(hItem, 'ABCDEF');
GUI_Exec();
HAL_GPIO_TogglePin(LED1_GPIO_Port, LED1_Pin);
GUI_Delay(500);
EDIT_SetText(hItem, 'XXXXXX');
GUI_Exec();
HAL_GPIO_TogglePin(LED2_GPIO_Port, LED2_Pin);
}
return hWin;
}
Supplement 3.4.2018:
The problem can be illustrated even more easily:
void GRAPHICS_MainTask(void) {
GUI_Init();
GUI_Clear();
GUI_SetColor(GUI_WHITE);
GUI_SetFont(&GUI_Font32_1);
GUI_GotoXY(100,100);
GUI_DispString('Hello world!');
GUI_Exec();
GUI_Delay(100);
GUI_GotoXY(100,200);
GUI_DispString('BAD ERROR'); // Text is on the Display if Delay < 20, Delay = 30 show turncated text
GUI_Exec();
Nothing can be output on the display if there is a delay longer than 50 ms after the GUI_Init ().
