Inverted Digital Outputs

[Corey Acker]

Hi, Is the option to invert digital outputs available in Wavesurfer? I'm using 0.981, and have been for a couple of years. But now I have an LED source with inverted inputs. According to the NI-DAQmx C Reference Help:

• int32 __CFUNC DAQmxSetDOInvertLines(TaskHandle taskHandle, const char channel[], bool32 data);

But I don't see that implemented anywhere.

On a similar subject of modifying tasks, how can I do things like change the AI input ranges? Previously, I could do this as the channels are created with the create command, or using DAQmxSetAIRngLow/High after they're created. I'm used to (old) ScanImage and having access to all the task handles.

Sincerely,

Corey Acker

Sorry, but WaveSurfer doesn't support either of those things.  For the input part, usually with 16-bit ADCs it's not necessary to scale the input ranges.  Doing so just means you're digitizing the noise more accurately...
