Although once or twice it did go back giving 57 seconds, now it remains at the other state, showing 140.
i'm pretty sure its not a code related problem, because i tested it on other systems. So it must be something related to the board.
Also, the board is heating...

Program optimisation on UDOO-Quad]]> 2 Fri, 24 Dec 2021 09:40:59 +0000 http://www.udoo.org/forum/threads/programming-language.500/ http://www.udoo.org/forum/threads/programming-language.500/ invalid@example.com (Ryan) Ryan
I'm pretty new to the ARM architecture, and Linux too. Bought a UDOO last week, and awaiting it's delivery.

Don't want to sound stupid, but i'm wanting to create some software to run upon it, just wondering what language i'm better writing it in.

I was told C++ would be the most suited, but just looking at other options too..

Thanks!]]> 4 Tue, 10 Jul 2018 16:06:18 +0000 http://www.udoo.org/forum/threads/running-a-qt-program-on-udoo-neo.16238/ http://www.udoo.org/forum/threads/running-a-qt-program-on-udoo-neo.16238/ invalid@example.com (nathans) nathans
I am very much an amateur at coding and embedded systems so please bare with me, I want to learn but my goodness I should have started years ago.

Anyways, I am using a Windows 10 host PC which adds a layer of difficulty because a lot of resources I have found online are for Linux based machines so they do not directly translate (or not in a way that I am able to comprehend).

Does anyone know of a decent tutorial for getting a Qt program to run on an UDOOneo board?

I need to set the IP Address to a static value and have it stay. the settings app seems to have no way to do this,

I found this article: https://community.freescale.com/docs/DOC-93626 titled "How to Add Ethernet UI Support in ICS"

In the article they had a link to an app to set the IP address and DNS.

They also have patches to apply to the compile of Android, I have never compiled Android.

It looks like the solution was to use the loopback device so I can use the Udoo's camera as a normal webcam.

Oh but wait... it's been deprecated in UDOObuntu 2.1:...

As a pre-order I'm not expecting to get my boards for another 2-3 weeks, but I know they'll be some amongst the kickstarters who a) have their boards b) have an interest.

Here is some info on getting it working (which is just a concise collection/summary from elsewhere):

• The UDOO has a Flex Bus/CAN Bus *controller* (two actually) built in but it doesn't have the transceivers.
  
• Having two controllers is really good...

I am trying to share data between the UDOO server and the Arduino. I currently have an Arduino Feather that I am receiving radio data from. Is there any way I can wire in the Arduino Feather into the UDOO Arduino interface, and then have it send data to the UDOO server? Ideally, I would like to save the Arduino data to an SD Card, and have the UDOO read from that same SD Card.
