回复： Could DAQmx C API be used under Ardency RTX programming in VC++6.0 ?

[sueswang]

Hello,my daq board is PCI-6120(S series),and I want to construct a real time system under Ardence RTX programming in VC++6.0,but I can"t get register level manual from NI,so I want to known if I could directly call the DAQmx C API in VC? If not,is there any precept to achieve it?

What hardware do your Ardence RTX System run in, is it NI's Hardware? Can your VC++6.0 run in Ardence system? And have you installed Measurement Studio?

Please tell me the details of your system.

   I want to construct a close loop system which contains a feedback channel.Initially,I directly programmed it in labview on Windows XP OS,and the input and output frquency must at least beyond 1000Hz,timing by OS timer,and this is unaccuracy,then I look for some paper about RTX which could create an independent thread under windows OS,so I think I could call the DAQmx C API under the thread created by RTX,but I'm not sure if DAQmx C API could be called under  RTX.

The hardware is my own PC(not NI embeded controller)and VC and RTX thread is runned under Windows XP,and I have not installed Measurement Studio yet.So is it be feasible,or are there other plan to construct this system under  Ardence RTX on Windows XP? Thank you!

You can use labview in the RT system, just install the labview RT engine.

RT OS and hardware is not available in my lab,another plan is to use matlab RTW which demands register manual,so I'm afraid I could only use RTX on Windows.If the DAQmx C API could be called,it should be feasible.

Only Labview 8.0 and earlier version support the RTX. You may need to install LabVIEW RTX Real-Time module 8.0 or earlier version.
