Hey Chilly

Thanks alot buddy! Ive been grutting through Labview which was made much easier since you decided to be such a nice guy. Ive tweaked the math to get Cuft produced by the fermentation. Its pretty cool, Im getting the DAQ card in the mail today. Cant wait.

Just one more question. How can I use your vi to measure on/off times and graph it the same way?

THanks again

Hello trimixdiver !

Nice to see  you made some progress ! Could you post the result of your work ? What is "Cuft" ? CO2 Cubic feet ?

I don't understand your question about on/off. Are you refering to the time between burps ? Could you explain ? You know I'm just a stupid froggy, and I have a "few" difficulties with english. Are you refering to the time between burps ? If you post your vi, I could add that rapidly...

The problem I have right now is how to get my PC DIO 24 card to show up in Labview???

Thanks

You need to install the DAQ drivers and reboot before you plug in the DIO board.  If you haven't done this in that order, the DIO might not show up.  If you have already plugged in the board before installing the drivers, you need to uninstall everything, reboot, install the drivers, reboot, shut down the computer and install the board.  When you bring the computer back up, the plug and play should automatically find the correct drivers for the board.  Hope this helps.

I dropped the channel I made in Measurement explorer on the vi you made. I will attach it to see if you can get it to work.

Thanks

Yea I can get the Digital I/O to work in Measurement and automation explorer ( I can see it go from red to grey) but I cant get it to work with the vi.

Please help....

Thanks alot

You do not have any DAQ functions in your vi.  I see the DAQ channel icon, but it isn't connected to anything.  Search for examples on DIO to see how to perform DIO functions.

I cant use the DAQ assistant VI becouse my card is older.

Where do I connect it to??? Im clueless

What are you using the DIO for?  You must be either putting out digital signals or reading digital signals.  Perhaps you are counting the number of times a signal goes from low to high.  This will determine how to use the DIO functions.  From the Labview splash screen, click on the arrow next to Open.  A submenu will pop up.  Click on Examples.  The NI Example Finder window will appear.  Click on the Browse tab, then double click on Hardware Input and Output.  Double click on Traditional DAQ, then double click on Digital Input and Output.  You will see a list of DIO boards (652x, 653x, ...).  Double click on the board you have and a list of example vi's will appear.  Highlite any of them to see an explanation of the vi on the right side of the window.  Double clicking on the vi name will open that vi.  You can look at the block diagram to get an idea of how to program with that device.  I hope this helps you get started.  If you still need help, ask again.
