Signal Express complete beginner

[JeanTheDummy]

Ladies and Gentlemen,

I'm completely new to Labview Signal Express. I want to complete the following extraordinarily complex task: blinking an LED 🙂

Unfortunately I loose my way either in the documentation, in the help system and in Signal Express as well.

What I have:

- Signal Express and Measurement and Automation Explorer installed on my PC.

- cDAQ-9172 is connected through USB, it seems to work.

- NI9219, NI9205 and NI9403 are connected into the base (cDAQ-9172).

- an LED with serial resistor connected to NI9403's port0,0.

- "Getting Started with LabVIEW Signal Express" document, june 2012. It matches with the SW version. (so-so)

What I can:

- in Measurement and Automation Explorer, I can change the direction and the status of port0,0. This way, the LED is ON and OFF, if I toggle it manually. So, the HW is working.

What I can't:

- I'd like to do this LED to toggle, for example by 1Hz, automatically. Whatever I do in Signal Express, it never works.

What I need:

- Has someone so many patience, that he could help me? (Before I take a huge hammer which can solve most of the problems 🙂 )

Thans in advance: JeanTheDummy

Add Step>>Generate Signals>>DAQmx Generate>>DIgital Output>>Line Output and configure as shown in attached image.

Hallo KateB, thank you for your answer.

I tried it the same way as you desribed.

I can toggle the LED manually, by clicking on High or Low, or by clicking on Invert Line.

It doesn't toggle automatically, as I wish.

(Toggling this LED is unimportant, it is just something like "hello world" in programming)

<Here comes the first picture>

I thought I can generate a square wave signal by 1Hz, and I can route it somehow to DAQmxGenerate, to make it toggle continously until I stop it.

So, I added a new step. But, the new step doesn't belong into the same circle, where the first step is. Probably it is the reason why it doesn't toggle the LED.

I have to modify the configuration to generate N samlples. Then, the two steps automatically belong together, without my intervention. But, still doesn't work:

<Here comes the second picture>

It requires an external clock - OK, let's give him.

The only possibility to choose from is here:

<Here comes the third picture>

This configuration runs errorless, but my LED is still dark 😞

Hey, where are my pictures? I inserted them ...
