External Trigger Control

[Whistmaster]

Hello there,

I have recently joined a new research group and have been asked to write a program in Labview (2018) that should be started by a button on a light source. The button interrupts the internal circuit of the light source to start the Labview program wich should then send it to a LED driver (LEDD1B by Thor Labs).

//E: I have a NI box: NI USB 6002.

Does anyone have an idea how I can start - a few keywords to search under?

Thanks for your help

The light source should send a light signal at 10Hz when the button on the light source is pressed. For this purpose, the trigger output of the light source is connected to the NI Box (USB 6002) (Input): here, the switch should be used to start the program in labview. Labview is to generate a signal (TTL) and send it via the NI Box to the LED driver, which then activates the light source.

Regarding the output: I surely need a DAQ device that generates the corresponding (10Hz) signal - Is a voltage out sufficient?

How can I read out the trigger signal?

A few keywords under which I get information would be helpful.

Hello,

You don't seem to have used LabVIEW before, let me give you some links to learn the basics :

http://www.ni.com/getting-started/labview-basics/

http://www.ni.com/academic/students/learn/

I know there is a lesson talking about acquisition/generation of data.

The NI 6002 is not the most suited to generate TTL signals but with only 10Hz required it should be fine with a digital output.
