Hey, I found out that the program was not hanging in the emwin Library but in a callback function / the event 'WM_NOTIFICATION_VALUE_CHANGED' of my application was waiting for a mutex there

Hello, I am using the emwin library as part of a bigger embedded application. I am experiencing a bit strange behavior: I am using the EDIT_Widgets to visualize some data (like current temperature, etc). My dialog looks like the following C Source Code (29 lines) This is a very simplified example. My problem is here, that the function "EDIT_SetFloatValue( hItem, fDummy );" in line 28 does not return. Since this functions hols a mutex in my application, it blocks every functionality that needs th…

Hello, this is the LCDConf.c (i attached the file because the post was too long) And these are the defined API functions: C Source Code (44 lines)

Hello, i digged more into our implementation and saw the following: We are using the 'GUIDRV_FLEXCOLOR'-Driver and the mode 'GUICC_M565'. When i try to take the screenshot using 'GUI_BMP_Serialize' the function 'pfReadM16_A1' is called multiple times to read the data from the LCD. C Source Code (8 lines) For example this function returns 3 2-byte-elements: 0xF79E 0xF79E 0x0000 The BMP-File is generated by: C Source Code (15 lines) The '_WriteByte2File' functions works as expected since every byt…

Hey Adrian, the '_WriteByte2File()' seemed to work well, the header of the Bitmap is written correct. However i simplified the function to write each byte instantly to the file: C Source Code (16 lines) So this does not seem to be the error, since i got *.bmp Files that i can open with any ImageViewer. However, the image is still just black. Do i have to change something else? Is the way i select the LCD as device the wrong way? Kind Regards,

Hey Adrian, i posted my function in the first post and you said that this function works very well on your end? Even if i debug and step through my implementation, i see that the Bytes passed to the C Source Code (1 line) function are correctly written into the buffer array and then to the file. Kind Regards,

Hey Adrian, okay, i just want to write the content of the LCD to the BMP file. I inserted Source Code (1 line) just before GUI_BMP_SerializeExBpp, but the Bitmaps are still empty. Or do i have to use a memory device to get the Bitmap? Kind Regards

Hey Adrian, i figured out one error in my software when i tried to copy the Bitmap over Ethernet, now i access it directly from my sd card. However, i just get unicolored bitmaps, for example i tried to save a 320x240 screenshot but the bitmap is just completely red (i uploaded it as attachement). Do you have any idea why this is that way? Kind Regards,

Hey Adrian, the dimension is 640x480. I just tested the center of the screen. Kind Regards,

Hey Adrian, why do you think i got a local "buffer" array? It is just declared globally and i use it in both functions. Kind Regards

Hello, i am using emWin in one of our µ-Controller Projects. I try to make a 'screenshot' of the GUI using the following Code: C Source Code (28 lines) However, i can't get a working screenshot. Am i doing something wrong here? While debugging i also saw that 'Data' ist just 0x00 most of the time. Is this correct?! Hope someone can help me with this. Thanks in advance and kind Regards

Hello, i got the following Problem: I set an EDIT Widget to Float Mode and when i try to assign a float value to the edit field emWin does not return. In a simplified way: C Source Code (1 line) => does not return. So i set the Floatmode to allow values 10 <= x <= 50. After that, i try to set the value 22 but here the SetFloatMode function does not return. However what is strange, is, if i set the value 30 instead of 22, the function does return: C Source Code (1 line) => does return. Am i missu…

Hello, in my application i want to use 2 different types of buttons and use 2 different skins to distinguish between them. Currently i am just using the FLEX Skin which i customized by changings its properties. However, is there a way to use 2 different types of the FLEX skin (for the same widget) which are just different regarding to their properties? Thanks

Hello, i can't find an API function to set the state of an EDIT Widget to enabled or disabled, they are just enabled by default. I tried EDIT_SetFocussable and EDIT_SetInsertMode, but none of them work for me. How do i set an edit field to a disabled state? Kind Regards
