Hi Stephen,
I have
already performed the changes you have suggested. Although a reduction of a few
percent on the CPU charge of the CRio 9022 was noticed, in the CRio 9074 the
code still doesn’t run @1KHz. I’m getting more and more convinced this isn’t a
code problem, due to the following experience I'll briefly describe:
i) when
running a single timed loop @1KHz in the CRio 9074, without any code inside it,
the CPU charge is already about 25%.
ii)
If
you add code to read from the FPGA vi’s indicators (without actually showing
the indicators), the CPU charge goes to about 50%...
iii) when you add RT buffer write code the CPU
charge goes up to 55%...and this is only with one timed while loop (no RT
buffer read, no TCP connections to the PC!).
iv) When
adding the second timed while loop code (@100Hz)
for buffer read and TCP connections, the CPU charge goes to 80%...
v)
In
this last situation, if you make the fpga and RT code to run automatically (without
showing any front panel) the cpu charge lowers to 70%...so you only get around 30% to actually
implement your code! If your controller isn’t very simple, you won’t get it to
work!
Anyway, thank you for
your help! Best regards,
João Barata
