I'm currently stuck with my NI USB-6211. I'm trying to generate a voltage waveform via an AO channel. I also want to record some signal (AI) and generate some pulse train using a counter.
I'm coding a C++/Qt software using the DAQmx ansi C library.
The Code I'm using worked, I used it extensivly on a different project (different computer). And It worked at the beginning when I installed it on the current. Then after trying to generate a pulse train it stop working (without any error send by the card) so I tested the card in NI max and even there nothing was working (both AO and CTR).
I noticed that when I try to start a task I observe a spike on the oscilloscope but that's all.
I tried to plug/unplug the card but without success.
