upgrade 8.2 from 5.x

Hi Jon,

Thank

In the pas I used to use AI (AO) Group config, Hardware config, Trigger config, Buffer config, clock config control,
Frankly, now it is not clear to me how how to convert all this VI. In addition, I do see the way work create channel and create task. I am looking for an example.
I also used to use PFI to synchronize the AO and the AI, is it still the same ?

Hello,

I am totally lost.

How to I configure a "list" of channels, ie choice the channel I want to use, set the gain (by given the min and max, and then get the real value), set the kind of coupling (DC or AC), set the kind of input mode (differential, RSE or ) with labview. I do not want to have to use MAX (at least the final user does not have to use MAX, in addition it is a too heavy application to run on old computer when running experiment).

Thank for your help.

Regards

All of those with the exception of coupling, are set with the DAQmx Create Channel function. What might help you get started is to use the DAQ Assistant. Use that to create a couple channels with different min/max values, modes, etc. When the DAQ Assistant is done generating the code. right click on it and select Open Front Panel. this converts the assistant to a normal VI and you can look at how the DAQmx functions are used.

I believe you need to use a DAQmx channel property for coupling. Since I've never used an NI DAQ board that had anything other than DC coupling, I've never had to use it.

Hi Jon,

With the new version of Labview numerous functions of Labview just disappear. I am just surprise to have to work so much to make my application working properly.
Would it be possible to get on old version of Labview ? 5 or 6 ? for free ? for Windows or Linux ?

Regards

PS Write now I am in trouble with write_Characters_file++1 and write_characters_files++2

[Dennis_Knutson]

I don't believe there were ever were built-in VIs called write_Characters_file++1 or write_Characters_file++2 in LabVIEW. These must have been custom functions written or modified from existing functions. There was a function called Write Characters to File (note: no underscore, no ++, no number). This old function is still available (but not on the palette) at vi.lib\utility\file.llb. Replace with this.
