Hello i have a very simple application on STM32f429 DISCO : alternatively display dialog box1 / dialog box 2 After a few second the blinking of the dialog box is very slow. What can happen the make the system slow down ? 1) Each dialog box has a 200ms timer that calls the other dialog box : case WM_TIMER: CreateFramewin_DLG_Startup(); case WM_TIMER: CreateFramewin_DLG_Status_menu(); 2) GUI_ALLOC_GetNumFreeBytes() returns 102948 free bytes 3) each dialog box prints bitmaps : case WM_INIT_DIALOG: …

Hello i have developped an application that shows PNG file in dialog boxes on the STM32F429 DISCO board. I switch between the dialog boxes on button press detection. I have noticed that the change of display is very slow (2s after a press on button). It seems when analysing the problem by setting led, that time is spent between button detection and (GUI_TOUCH_StoreStateEx) and the callback call with WM_NOTIFICATION_CLICKED. Here is how i realize the switch : case ID_BUTTON_LOAD: // Notifications…

Hello, i added the truetype folder to my stm32f429i_disco project. But when i call GUI_TTF_CreateFontAA i jump directly to the HardFault_Handler. The code runs well in simulator. In the main i have : =============== GUI_Init(); GUI_Initialized = 1; /* Initialize RTC and Backup */ RTC_Init(); /* Activate the use of memory device feature */ WM_SetCreateFlags(WM_CF_MEMDEV); /* Do the calibration if needed */ CALIBRATION_Check(); Then i enter the mainTask ===================== void MainTask(void) { …

Hello, thank you for your reply. In the project there is a call to GUI_ALLOC_AssignMemory(aMemory, GUI_NUMBYTES); with GUI_NUMBYTES = (1024) * 140; This memory is allocated for general use of emWin ? That is to say that if i want to use a 13*13 PNG file i have to allocate 14*13*4 + 54Kbytes = 56Kbytes ; so i must define GUI_NUMBYTES = (1024) * (140+56) ? Thanks in advance best regards
