Creating application with different tasks, Qt or anything else?

Hi I want to blink my led, do a serial communication, update my display at the same time in beagleboard xm.(multitasking).

I am using Sitara SDK, I havent got previous experience with using ccsv5 or Sitara. Is it possible to accomplish this task?

I am using the u-boot and kernel provided with the latest sitara. How to do multitasking thereafter? Should I use Qt or something? Or could you suggest me anything else?

Also how to do debugging?

Regards

Hi Badri,

simplest attempt would be to create an application for each task (UNIX
way: On eapplication for a certain task) and do communication between
the applaications via rpc/pipes or such.

If you want one application only use fork/exec to create concurrent
tasks.

The multitasking itsself is handled by the linux kernel (scheduling).

HTH!

Hi meino,

Thanks for your quick reply.

What I have previously attempted is I created executable of qt, and I made a script for autologin and autostart that application.

That means Is it like I can use RTSC provided from ti?

Could you show me any example projects or something implemented like this?

Thank you once again

Hi Badri,

no, sorry, I cant give you examples here.
the fork()/exec() system call is part of any UNIX system and base of
UNIX system programming. It is included in the C-library. For that
you dont need any other library.

RTSC is a real time approach. This something totally different.
Real time programming means that a certain task has been finished
in a predefined time.

It looks like you are comparing apples with houses :wink: (no punt
intended!).

For UNIX programming and fork()/exec() look here:
http://www.osix.net/modules/article/?id=641

Be prepared that if you want real multitasking combined with real time
programming on a system, which does not compare to "real PCs"
(again no punt intended!), you will have to solve several <hrrmmmm>
challenges....
Especially when audio/video recording/playback is
involved.

HTH!
Best regards,
mcc
