Hi Andreas,
I think explain not so good my goal.
I write a C application (ethercat.c) that read the position of the motor
and send a velocity command.
In this application I use a RTAI contest for the cyclic task.
Now I wanted to realize a scicos block where in output I have the
position of the motor and like input the velocity command.
I'm using scicoslab in RTAI contest and I have three ways to procede.
1. I try to use the C scicos (where put ethercat.c) block but when it
ask me some lib don't work.
2. Another idea that I have is run ethercat.c and export the data in
scicoslab. At this moment I use a fprintf to write the position of the
motor on a file and read it from scicoslab. But it is a very bad
solution cause fprintf (or use a printf to shell) in rtai contest.
3. In the end I know that is possible create a custom scicos block,
writing an interfacing function (.sci file) and an implementation
function (.c or .sci file). But I don't understand if my ethercat.c have
to become the implementation function or I have to realize the two
function (implementation and interfacing) and run ethercat.c.
Very greatings
