I am really new in rtlinux and i will be agreed if anyone could help me.
i am trying to convert a c++ program to a rt linux program. The thing is
like following. I have an graphic interface and i call a function that
captures images. Making a while() i can do it video. But i want to
control this bucle and for it, the frequency of video capture. The task
of Acquiring needs some parameters passed by the rest of program. I
think of make the acquiring task a rttask and make it periodic like i
need. Questions, please tell me if i am wrong or not and why.
1.This task, i won't be able to call of the program, and like an rt i
will make a module and installe it in memory.
2.After, the communication will be with a FIFO. But how i can
communicate the two tasks(-rttask who is periodic to take images- and
-the interface and rest of calculs task in normal linux-). Can i pass
all kind of data by FIFOs. I need exactly to pass structures and so.
3.In the rtlinux task. Can i access to all resources like if it was a
linux task? Because i have to use functions of the camera and the
driver...I don't know if i could call from the rttask to the functions
provided by the driver, that is possible to call from linux.
4.Suposing that it is good. The thing will be to install the module.
After running the linux program and when it writes in the FIFO the
parametres that the rttask need it will be work? or it has to be an
event to make the rttask start to work in this case.
Thanks you..
