[Jsbsim-devel] Matlab S-Function - Do I feel happy or sad?

[Philippose R. <sa...@ro...>]

Hello people,
  A good evening to you all :-)!

  Well...I was scouring the net for Simulink
S-Functions capable of setting up a TCP/IP Connection,
and what do you know....:-)

  Check up the following site:
      
http://www.it.fht-esslingen.de/~zimmerma/software/IOlib.htm

  I dont know if I should just stop trying to come up
with my own S-Function, or continue with that attempt.

  Here are the highlights of the above set of
utilities:

  1. It has both Matlab command line, and Simulink
block interfaces

  2. In Simulink...it also has a block called
"RTCTime"....which adapts the simulink simulation step
size during the simulation, in order to make it run in
"real-time"..as in..."wall clock..real world"
simulation rates.

  3. It can create TCP/IP servers and clients

  4. It sends out data which comes into its input
ports from Simulink (unlimited number)...in the form
of a character string with the following format:

     "t=...\nch1=...\nch2=...\nch3=...\n" 

  5. It can accept a maximum of 16 values (channels)
as input from a TCP/IP port, read into the system
again using the same format as the send command as
shown above, and extracted and sent out to output
ports (or was it a single multiplexed output
port...but ya...the same!)

  6. It it written by a university professor...and is
distributed only as DLLs...and though free for
non-commercial use, is clearly stated as not being
Freeware.

  So...what is the vote? Do I continue with my own
version of a Simulink-JSBSim interface, or do we adapt
JSBSim to work with the above utility libraries?

  In a way I am happy, in that...there does exist a
solution...but on the other hand...solving such
problems always give me satisfaction, which is being
taken away from me by this set of utilities :-)!

  Hmmm.....!

  Have a nice day!

Regards,

Philippose
