Qt for MCUs

@jsulm i tried with QUL_COMPRESSION ON .but its not decoding properly

Thankyou for your quick reply Mr.hdonahue. Here we are using arm processor AM4378 based custom board. All Digital ios of ic are connected to gpios pins of processor and also the hardware switches are connected to gpio pins. So the logic of hardware is when we rotate the position of switch the gpio values will set. That hardware logic is implemented. At the same time i want to see that in ui application . so that the application will sense the change of switch position and will show gpiox is setted like that and the switch goes colour change in application . This is overall plan so to do that the qt application have to sense the change in position of switch. So only way it will sense when we use interrupt method but i am not getting how to this . Can you please help me in regards. Apologies for the long post.

@aha_1980 Thank you for posting that. Sorry I didn't get the notification with the suggestion. This is a great community.

@IRBaboon If your PC have no obvious lagging, my issue is an error direction. Here are some ideas you can try: read help doc seriously or test one other poeple's credible demo on your devie, is it possible to call it incorrectly?(for serial device, It is difficult for others to run your demo) try the lastest verion of QT

@jsulm 😢😢😢

@misu said in Some problem with "qmltocpp": did you have the same problem? I never used Qt for MCUs. You did not answer this question: Did you check what is inside /home/mi/Qt? The error message tells you what QtCreator is looking for.

Here is another video tutorial specifically about using Qt Design Studio with Qt for MCUs: https://resources.qt.io/qt-on-demand-webinars/get-started-creating-dynamic-uis-with-qt-design-studio-and-photoshop-on-mcus-on-demand-webinar-2

@ylopes That was it Thanks!

You could programmatically change the contentX and contentY properties of the ListView and use a Behavior to animate the change of these properties. Here is a small example: import QtQuick 2.0 import QtQuick.Controls 2.0 Rectangle { width: 480 height: 272 ListView { id: list width: 380 height: 480 interactive: false Behavior on contentY { NumberAnimation { duration: 500 easing.type: Easing.OutCubic } } model: 30 delegate: Text { height: 40 width: list.width verticalAlignment: Text.AlignVCenter horizontalAlignment: Text.AlignHCenter text: index } } Button { id: button anchors.right: parent.right height: 272 width: 100 text: "Scroll!" onClicked: list.contentY = (list.contentY === 0 ? -300 : 0) } }

@Sachin_Og https://doc.qt.io/QtForMCUs/qml-qtquick-borderimage.html#border-prop so border.color property is missing. Can you raise a feature request for this from the Support Portal of your Qt Account? [image: b3b5785a-819b-46bd-aec1-7e6b30e1377d.jpeg]

@Sachin_Og IIRC https://doc.qt.io/QtForMCUs/qml-qtquick-controls-swipeview.html#interactive-prop set that to false

You can find the list here: https://doc.qt.io/QtForMCUs/qtul-supported-platforms.html#supported-boards-from-st These are the ones with out-of-the box support, but other MCUs can be adapted as well.

There is an example in the Qt for MCUs SDK named "interrupt_handler". This should help you see how you can include sources from a STM32CubeIDE project. Integrating Qt for MCUs in a STMCube project might be possible today but I don't think it's straightforward and we don't have documentation for it. This is something we will be looking into in the near future, to support this kind of use case "out-of-the-box".

Thank you ylopes, it works. Yes I watched the video for 1.0 release and currently I am working on 1.2 version. I missed the documentation. Thanks for the link.
