Help for a newbie

[Samuel Garcia]

Hi Luke, hi all,
I starting to play with acq4 with a ultra simple scenario.
I want to record 3 channels and play on output some custom stimulation.
The TaskRunner seams perfect for that.

We have an NI USB 6211 (16 AI and 2 AO).

For the moment I am fighting with NiDAQ. So this is just a an early stage.
I got this error at the bottom and I am wondering if there a particular ddl version to install.
I taken NIDAQ1711f0.zip from NI.

When starting acq4 for the first time there is a full scan of this DLL or header.
I don't understand the mechanism in acq4 for accessing the DDL.
At the end the crash with a very simple things "DAQmxGetSysDevNames"


Do you have any clue ?


Best,


Samuel

Hi Samuel!

I think we have seen this error before: https://groups.google.com/d/msg/acq4/swlSoUSsbvE/Uq0qQWaxCwAJ

Can you try out the suggestion there and let me know if it helps?

Luke
