Transition from NI-DAQ (Legacy) to NI-DAQmx

Hi,

 

Our APP is based on NI-DAQ (Legacy) driver developed function based (nidaq32.lib) and used to run on WinXP. But, as we are moving to Win7(64bit), it needs to be ported to NI-DAQmx which is supported for Win7.

 

We are using different APIs DIG_* in our app but there is no such APIs in NI-DAQmx c help doc.

 

I see on ni website, it is mentioned that we can use existing APP developed on legacy driver even with NI-DAQmx using transition libraries developed by NI. I didn't find those.

 

Could you please help where can I find libraries which could bridge gap between app dev on legacy driver and work with new DAQmx driver??

 

 

For users who plan to upgrade to NI-DAQmx but want to use their current Traditional NI-DAQ (Legacy) applications with new NI-DAQmx-supported hardware, NI has created the Traditional NI-DAQ (Legacy) compatibility VIs. These VIs replace certain Traditional NI-DAQ (Legacy) VI libraries with libraries that work with both Traditional NI-DAQ (Legacy) and NI-DAQmx. These VIs look identical to the existing Traditional NI-DAQ (Legacy) VIs and integrate seamlessly into existing applications. The compatibility VIs were created to use while waiting for the application to be rewritten using NI-DAQmx, but you can still use NI-DAQmx-only devices. 

Note: These VIs do not support all features on all devices and are not guaranteed to be updated with future revisions. To learn more about these VIs, visit ni.com.

 

Thanks,

amandil

Thanks. This seems to be for application developed using labview. What if application is *daq.exe in C/C++ compiled with functions from NIDAQ like DIG_* with nidaq32.lib? Is there any corresponding lib for NI DAQmx?

The note says it was for LabVIEW. I'm not aware of any other transition library.

Thanks again for prompt reply. I will check if labview VIs can be used.

That is because a driver does not exist.
