Hello. Can I make the modal window only for one parent window? For other windows this window will not be modal.

I fixed it. Could not work for you, because problem in the driver. You need to fix the function DMA2D_MixColors() #if (GUI_USE_ARGB == 1) #define DMA2D_ALPHA_CMP_COLOR 0x00000000 #else #define DMA2D_ALPHA_CMP_COLOR 0xFF000000 #endif static LCD_COLOR DMA2D_MixColors(LCD_COLOR Color, LCD_COLOR BkColor, U8 Intens) { if((BkColor & 0xFF000000) == DMA2D_ALPHA_CMP_COLOR) return Color; uint32_t ColorFG = Color ^ DMA2D_ALPHA_CMP_COLOR; uint32_t ColorBG = BkColor ^ DMA2D_ALPHA_CMP_COLOR; ... return (Color…

STM32F429 COLOR_CONVERSION_0 = GUICC_M565 DISPLAY_DRIVER_0 = GUIDRV_LIN_16

With this in other examples, all the same. What version of IAR should it be? I have a 7.50.3.

Hello. In the library STemWin540_CM4_IAR_ARGB.а alpha blending does not work. In the library STemWin540_CM4_IAR.A alpha blending works. Checked various options with functions: GUI_EnableAlpha(), GUI_SetAlpha(), GUI_SetUserAlpha(). Is it a library or configuration problem?

Before GUI_Init, you need to enable the CRC module. This STemWin feature is specified in the STM documentation.

Hello. What is the recommended size for the block memory GUI_BLOCKSIZE? Function set GUI_ALLOC_SetAvBlockSize(GUI_BLOCKSIZE)

Hello. LCD_ControlCache() I tried, there was no result. To date, there is no way to buffer the data pointers that need to be displayed? To output these pointers using the interrupt DMA2D. Is such a functional expected in the future for the full use of DMA2D?

For the keyboard, make an unedged window without focus. More precisely, if the focus is lost, the keyboard window fills the focus back. The parent for him is the background. And it is always on top of other windows.

I did not correctly put it. Meant what to use MemDev superfluous and it will take up resource resources. Is it so? Sorry for my English.

I understand, the chain of calls is this: GUI_EXec() ..->_LCD_DrawBitmap16bpp() ....->_DMA_Copy() ......{ ........................... ........DMA2D->CR |= DMA2D_CR_START; ........while(DMA2D->CR & DMA2D_CR_START) ......} if I write the parameters of the _DMA_Copy() function in my circular buffer and I will call them using DMA2D_ISR_Handler(), then the picture collapses. Since the pointers for _DMA_Copy () will no longer be relevant. Can I use it LCD_ControlCache(LCD_CC_LOCK) and LCD_ControlCache…

Hello. Do I understand correctly? What if using Multiple Buffering, then MemDev can not be used?

Dear Segger. Is there an option in EmWin, determine end of transmission DMA2D, using the interrupt DMA2D_ISR_Handler() . And do not use poling while(DMA2D->CR & DMA2D_CR_START). Example in the previous post.

see function WM_GetId().

Got it. Thank you. Where is the memory area for Multiple Buffering? How much memory should I allocate?

Hello. Used controller STM32F429, LTDC, DMA2D and LCD 7 inc resolution 800x480 pixels. For example, the function of copying the buffer looks like this: static void DMA2D_CopyBuffer(uint32_t layer_index, void* pSrc, void* pDst, uint32_t x_size, uint32_t y_size, uint32_t off_line_src, uint32_t off_line_dst) { uint32_t PixelFormat = GetPixelformat(layer_index); DMA2D->CR = 0x00000000UL | (1 << 9); // Memory to memory and TCIE /* Set up pointers */ DMA2D->FGMAR = (uint32_t)pSrc; // Source address DM…

Hello. Tell me what is more efficient to use for Multiple Buffering: VM_MULTIBUF_Enable (1); or for each dialog, window static void _cbStatus(WM_MESSAGE * pMsg) { ... switch (pMsg->MsgId) { case WM_PRE_PAINT: GUI_MULTIBUF_Begin(); break; case WM_POST_PAINT: GUI_MULTIBUF_End(); break; ... } }
