Qt World Summit: Submit your Presentation

Example for embedded linux

  • I have a Linux ARMv7 device running Ubuntu 16.04.2 LTS with a touch screen. The processor is pretty underpowered and we are looking for a UI framework that will provide simple graphics and animations in a performant way.

    Are there any out of the box examples that will run on that device? I have no Qt experience but just need a quick way to determine if Qt is a potential solution for us.

    How much underpowered ?

    You might want to take a look at this article. It talks about MCU but should give you an overview about Qt on low powered system.

  • It has about 1 GB a RAM and here is the cpu info:

    Architecture:          armv7l
    Byte Order:            Little Endian
    CPU(s):                2
    On-line CPU(s) list:   0,1
    Thread(s) per core:    1
    Core(s) per socket:    2
    Socket(s):             1
    Model name:            ARMv7 Processor rev 10 (v7l)
    CPU max MHz:           792.0000
    CPU min MHz:           396.0000
    Hypervisor vendor:     (null)

    I'll have a look at the MCU doc.

    @dland See https://doc.qt.io/qt-5/qtexamplesandtutorials.html
    But you will either need to setup a cross compile environment and build Qt + examples or do that directly on your device.
