control keypad from labview

[braxat2000]

Hi,

I would like to connect a keypad 4x4 and monitor it from Labview.

In the past I implemented a simple algorithm which scans the rows and coloumns of the matrix, but is there an easier way to do this in Labview?

I don't mean a virtual keypad, but an actual one. I would like to use Crio with RT as my controller

Thanks,

Eyal.

Hi Braxat.  WHy don't you use the parallel port of your computer?  it's a mini-DIO port.  Just to give you an idea. 

To just read a keypad, it's a really expensive solution to use c-Rio

Kind regards,

Hi,

I won't have a PC for this instrument, but it will be an autonomous testing equipment.

Monitoring the keypad is just a feature I need to add to this instrument, so I can't have shortcuts. I hoped an elegant solution already available in Labview existed, but maybe I'll have to use 8 channels DIO module for scanning the keypad.

If there is a nicer solution I'll be happy to hear about it :).

Thanks,

Eyal.
