Complete noob - want to measure voltage with manual start and stop

[youngc]

Hello

As the subject says I am a complete noob when it comes to programming NI.

I am looking for someone to point me in the right direction

Setup:

Windows8 Desktop

Visual Studio 2013

NI 6255 PCI DAQ card

NI SCB-68 Connector Block

What I want to do:

I want to write a console application to measure voltage on signal ai16

-- I want to be able to manually start and stop the application

-- I want to be able to output the measured voltage to a csv file.

Where I am at:

I have compiled and run the "NI-DAQ\Examples\DAQmx ANSI C\Analog In\Measure Voltage" example

It says that I have "collected " samples but I dont know what that means, since I do not see an output file..

What I do not understand:

Samples - I do not understand this or even know where to start

File output - how do I get the file to save the data that is collected.

Thanks in advance

Chad

A 'sample' is a single voltage reading performed by the analog to digital converter. Multiple samples are usually separated in time by a convert clock that is specified in samples per second or Hz.

I believe this could be a valuable resource for you to use or reference in trying to log your data:

Hi Arron

Thanks for the link, unfortunatly, it did not help because the instructions were for Visual Basic and not C++. This was my fault for not putting the prog language that I needed help with in my initial post.

However, I did start to find help on this link: https://www.ni.com/en/support/documentation/supplemental/21/using-ni-daqmx-in-text-based-programming...
