Software Dev / Building Qt-creator

« on: November 09, 2018, 02:48:24 AM »

Dear Krontech,

I am trying to build Qt 4.8.7  on an Ubuntu 16.04 OS.
But the configuration fails and I cant make && make install . The error message I get when running the qtconfig.sh script is the following:

"Creating qmake. Please wait...
make: Nothing to be done for 'first'.

You have not explicitly asked to use pkg-config and are cross-compiling.
pkg-config will not be used to automatically query cflag/lib parameters for
dependencies

The QtDBus module cannot be enabled because libdbus-1 version 0.93 was not found."

I followed the steps from the github rep. Do have any experience with this error?

I have tried google, but many different solutions come up.

Cheers,
Maja

Software Dev / Monitoring value on IO trigger

« on: August 02, 2018, 05:36:22 AM »

Hi Krontech,

Is there a way to monitor the value on the trigger inputs in the software?

I would like to constantly monitor the value (low/high or 0/1) on the trigger inputs, like you can do on e.g. a GPIO pin. The idea is to send this value to a pixel on the image, thereby knowing if the given trigger input was low/high during that specific frame.

Cheers,
Maja

Chronos User Discussion / NTP for precise timing

« on: August 01, 2018, 12:22:21 AM »

Dear All,

I am using the camera for scientific purposes and I need precise timing. Ideally I would like to install ntp (network time protocol) and use it to synchronize the camera time to my computer which is connected to a GPS. I am trying to find a ntp package already compiled for the camera processor type (armv7l), but so far, no luck.

Do any of you have experience with this or other methods for precise timing on the camera?

Cheers, Maja

Software Dev / Deploying camApp from Qt Creator

« on: March 20, 2018, 02:30:16 AM »

Hi, I am using Chronos 1.4 for a research project and so far I am very happy with it. I need to make some changes to the software for it to function ideally for my project.

Is anyone here able to deploy a modified version of the camApp from Qt and use the camera afterwards? If so, can we share experiences?

I have installed the Qt creator following the README guide on github. Everything seems to be working and I am not getting any error messages. So far, I have not made any significant changes to the app before deploying it (I have simply changed the spelling on the main ui, just to see if it works), but I cannot use the camera with the “new” version of the App.

I am working on Ubuntu 16.04 and the Qt creator is version 3.5.1.
