Example for embedded linux

dland

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.

Hi,

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:

$lscpu
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.
