Hello Matt thank you for your answer, I'm sure that realtime scheduling is
enabled because my program don't print the following warning:
r = gr.enable_realtime_scheduling()
if r != gr.RT_OK:
print "Warning: failed to enable realtime scheduling"
So, My computer is not fast enough to run my program en real time? How can I
fix it? I Have a Pentium IV 3.0 Ghz HT
Thanks a lot.
