how to use labview program receive arduino 2560 mega digital sigal

Dear Nap,

Exactly, I wanted to play video file when read 13 pin signal no matter for is high (1)  or low (0)

[Dennis_Knutson]

What's the point of even reading the arduino if you don't care? Just play the video.

Dear Nap,

I have video file already, I wanted to know how to connect output parallel with boolean and play my video file at the same time.

Dear Dennis,

Should you have simple labview program (no need arduino, 8051...etc) for read usb com port digital high (1) signal, hence trigger file (play video file)?

Many thank for your help!

Dear Chan, my friend, 

Could you please tell us in real simple words what are you planning to do? 
Here are few things we understood from what you've just told:

1. You have an Arduino connected to your PC.

2. This PC is running LabVIEW.
3. You are trying to communicate LabVIEW with Arduino using LIFA (LabVIEW Interface for Arduino) toolkit.
4. You have connected a switch with one of your Arduino's digital pin OR some other device which will make this pin either go HIGH (True) or LOW (False).

5. You want to play a video file whenever the pin goes from LOW to HIGH (OR high to low but can't be both).

If you do not care about the pin's digital state then what is the point of monitoring it? And what do you mean by "READ USB COM PORT DIGITAL HIGH"?

Regards.

Dear Nap,

Pl to see in red

1. You have an Arduino connected to your PC. Yes

2. This PC is running LabVIEW. LabVIEW 2012

3. You are trying to communicate LabVIEW with Arduino using LIFA (LabVIEW Interface for Arduino) toolkit. Done, I through LIFA communicated with arduino already.

4. You have connected a switch with one of your Arduino's digital pin OR some other device which will make this pin either go HIGH (True) or LOW (False). I wanted to use digital signal pin (0 or 1) to execute existing video file in my PC. 

5. You want to play a video file whenever the pin goes from LOW to HIGH (OR high to low but can't be both). Exactly.

If you do not care about the pin's digital state then what is the point of monitoring it? And what do you mean by "READ USB COM PORT DIGITAL HIGH"? I attached the opertaing chart for your kindly review and comment.

What media player are you using? Does It have an error in connection? You could also put it a single frame of a sequence structure. Use a state machine and set the next state to be play media, etc.

Dear Dennis,

I prefer media player is Window Media player or other common player, mpcstar, winamp...etc.

Is need separate single frame? The file path can connected with led output together?

Dear Nap, Dennis,

Pl see attached my using arduino model for your comment.
