Hi Florian Thanks for reply. The problem is solved. According to Emwin manual, button reaction to Enter key is equal to pressing button and releasing it immediately. Therefore both WM_NOTIFICATION_CLICKED and WM_NOTIFICATION_RELEASED callback routines must be fired. Best regards, Haia_Boosa

Hello everyone I have created a simple GUI by means of GUIBUILDER app. It consists a window and one button. A matrix keyboard is used and the keys data are passing to Emwin by executing WM_StoreKeyMsg(KeyValue,1) and WM_StoreKeyMsg(KeyValue,0) in interrupt routine, when the keys are pressing and releasing. The problem is that both WM_NOTIFICATION_CLICKED and WM_NOTIFICATION_RELEASED callback routines are fired when just pressing and holding the button (executing WM_StoreKeyMsg(KeyValue,1)). Wher…

Thank you so much

Hello Sven, Thank you for replying. According to your estimation 155 KB memory is needed for 320×240. My MCU has 192 KB of RAM, but it is splitted into two region(128 KB RAM and 64 KB CCMRAM) that aren't continues in the memory map: CCMRAM ORIGIN: 0X10000000 LEBGTH = 64KB RAM ORIGIN: 0X20000000 LENGTH = 128KB Is there anyway to use this kind of memory for Emwin?

Hello everyone I created simple GUI with GUIBUILDER app (window with background color and two buttons). Keyboard events is passed to emwin by GUI_StoreKeyMsg() function(inside the keyboard external interrupt routine) and all of program is in the super loop that execute every 30 mili second. By pressing TAB Key buttons is respectively get focused but this cause screen to flicker. I use STM32F407 with internal RAM (120 KB of RAM is dedicated to emwin) and ili9341 LCD Controller. Can anyone help me…

Hello Mark Please share your main function.

Thanks for quick replies.

Hi Is there any way to draw a circular gradient like the attached image by emwin? Thanks All Haia Boosa

Thanks a lot Florian.

Hello How Can I overwrite GUIBuilder window creation callback. I want to draw a window with gradient background color. I tried the following modification on GUIBuilder output, but i did not work. (Compiler warning is included at the bottom of code) C Source Code (138 lines)Thanks in advance

I did not call WM_DeleteWindow() twice on the same window. Based on user interaction a custom message box (framwin) is created and deleted by pressing OK button on the message box. It works well in first creation and deletion, but doing same action i.e, pressing OK button (deleting the window) will cause Hardfault. Best Regards, Haia Boosa

Hello everyone What is the best way to delete a framwin widget or a window? When I use Wm_DeleteWindow(), it works fine in the first call but it results Hardfault in the next calls. Thank you very much

Hi Sven Thanks for replying The configuration is as follows: C Source Code (89 lines)Target is STM32F407 and LCD driver is ILI9341. SRAM settings is verified by writing and reading back from 8,16 and 32 bit defined variable in the SRAM address range. Best regard.

Hello everyone where can I find more detail about aMemory array ( the following code): C Source Code (1 line)Detail about how and where the screen pixels information located in the aMemory array. I have some problem when I use external SRAM as GUI memroy in STM32F407. It's look like that the image within LCD has been shifting upward in the SRAM mode. Thanks in advance

Hello everyone I'm working on STemWin532 library on STM32F103ZET6 bord in STM32CudeIDE. I could successfully configured LCD interface (The Controller is HX8325B and GUI runs on internal RAM) and insert some text on the screen (image 1) But when i use external SRAM as GUI memory result is very strange and interesting :). The text is driven out of the screen. The picture 2 shows the situation. While the code is the same code that works correctly in the internal RAM of MCU. The only command that i …

Hi everyone I'm using STM32F103ZET to run STemWin532 GUI. In the first step i configured everything for running from internal RAM and program worked fine and GUI displayed components like progress bar and ...., but when i changed linker command file to map GUI memory to external SRAM GUI did not work. I checked connection with SRAM and it was OK. I checked 8,16,32 bit memory accessing integrity by following code: C Source Code (31 lines)We can write to External SRAM and read it back successfully…
