  • Hi, the key input from the client should be sent to the VNC server. In emWin, there are two ways to react on keyboard input. It depends whether you are using the window manager, or not. When using the window manager, have to react on the WM_KEY…

    Hi, Quote from bio_med: “GUI_TOUCH_CalcCoefficients(NUM_TOUCHSCREEN_CAL_POINTS, ReferenceX, ReferenceY, SampleX, SampleY, X_Size, Y_Size); ” this routine is used for calibration. Before you can do that, the touch points have to be retrieved from the…

    Hi, I forgot to mention that the sample cannot be used on capacitive touchscreens. Are you using a capacitive or a resistive touchscreen? And how do you pass the data sent by the touch controller to emWin? Best regards, Florian

    Hi, I cannot really say what is going wrong without knowing which hardware you are using or what you are doing after the calibration in your application. Can you provide me some information and code to reproduce the behavior? Thanks and best…

    Hi, we were able to reproduce the behavior and are looking into it. I found that the file dialog would still be opened when pressing CTRL + O. Best regards, Florian

    Post
    Hi, it should work when calling GUI_QR_Draw() in a WM_PAINT case instead of WM_INIT_DIALOG. In fact, you should only draw inside of a WM_PAINT case when using the Window Manager, or otherwise it won't work properly. Best regards, Florian

    Hi, thanks for your feedback! Let me help you with your problems. 1. In order for something to be displayed, you should make sure that the text color is different from the background color. And you also have to set a text to the TEXT object. To do…

    Hi, yes, you can convert the XBF file into a binary array by using the Bin2C tool. The array only has to be addressable. The GetData function then only has to copy the array to the source address. C Source Code (25 lines) Best regards, Florian

    Post
    Hi, I would advise against the use of SIF fonts, since this font format is considered obsolete. It makes more sense to use XBF fonts instead. XBF fonts can be created from installed fonts using the Font Converter tool. If you want to store fonts in…
  • Hi, PNG decoding requires a lot of RAM, but given that you allocated more than 6MB to emWin, this shouldn't be the problem. It could be something wrong with the PNG image itself, have you tried using another PNG image, just to see if that works? You…

    Hi, you can't import emWin code into the AppWizard, you would have to develop the application from scratch with AppWizard. Though, when you already have an existing application, this part should be really easy once you know how to use the tool. You can…

    Hi, unfortunately it is not possible to draw such a gradient using emWin. It would be best to draw this gradient using a bitmap, which is faster anyways. Best regards, Florian

    Hi, the GUI_WIDGET_CREATE_INFO structure is defined as follows: C Source Code (12 lines)As last parameter you passed a pointer to a callback function, where the number of extra bytes to be allocated should be. So instead of _cbWin, you can just pass 0…

    Post
    Hi, you can only use the GUI_MAKE_COLOR() macro with ABGR colors, not ARGB. With emWin V5.44, the default color format was changed from ABGR to ARGB. It is not that important to which color format you are using, but important is that you don't pass…
