回應： Re: May I just close DOS window when I want to finish work?

[cychang0829]

When I writing my program in C, there is a thought come to my mind.

May I continuously output data, like I/O or AO, in a while loop,
and just close the DOS window when I want to finish my work?
(though there are many example of AO set output 0 V at the end of code.)

If it is work, and doesnt harm to the card, it may be easier for my programing.
I am wondering if this is OK for the card?

Thanks

It should be OK.

May I know which OS? which C complier? which NI hardware? which NI-DAQmx version? or which NI-DAQ version?

Thanks

Thanks Wu,
Here are the information:

OS                    : Windows XP professional
C complier        : Microsoft Visual C++ 2005
NI hardware      : PCI-6711
NI-DAQ version: 7.1.0f1

If it is OK to close DOS window directly,
the AO output might be hold the last value.

It is OK that dont output 0 V of AO after work?

Hi

As u said, the device output will keep the last value if u don't reset it.

i suggest u to reset the device or change the output value to 0 after finish your problem.
