DAQmxCfgSampClkTiming with NI 6220 and ati nano17 f/t sensor

Hello abcdcadb. I hope you have solved the sample rate problem. I have exactly the same problem now. Could you give me any clue?

Hi, 

I actually solved that issue.

However I doubt about your case, you also use the same hardware and software platform like me or just exploit a similar library of data acquisition from NI?

Unfortunately, that was project in my former company, I did quit there last year and according to policy, I could not bring all of source code .

I will review document again and let you know the cruxes of problem if possible

Yes, of course. I'm using the Visual Basic example from the ATI page. However I'm using also the NI USB 6009, not the NI 6220. I already modified the DAQSys.cpp where all the data acquisition parameters are set but with no results. It seems the sample rate doesn't change. I'm starting to think that the USB 6009 is not enough for the sensor. I can share the code that I'm modifying in order to make you remember. I'm doing my PhD and there is not problem about sharing. 

P.D. This is my real profile: JoséDan. Apparently the last time I posted with another. Sorry.

I have split you post to mb e new thread.   You don't have either one of the problems in the original discussion nor the same hardware.

Please restate your issues in this thread.   I will try to make time to help.

Hi there,

hope you got the solution, I was flooded in project and could not spend time to check 😞

There were 2 ways I approached :

1/exploit another sample code from ATI (written in VB), sampling time could be easily adjust, then make VB app run as latent thread and call it on your main app (or re write on VB ).

2/ there is a text file listed specification of hardware, your main function calls it to recognize hardware, discreetly find and check it.

i couldn't go further due to no source, but I will be willing to help if you find something
