push buttons hardware with usb-6008

[Flibbertygibbet]

I'm creating this whack a mole game.. how to do I implement the push button switches hardware connected to the NI-USB6008 input? Can someone give me a headstart pls? I'm stumped..

Please don't tell me you attached a VI that was set to run when opened.

I try downloading your VI and it popped up with a dialog box saying there is no disk in the drive, and to put a disk into \Device\Harddisk3\DR7.  That or it seemed to be looking for an H: drive.

As for switches, look at page 21 of the manual http://www.ni.com/pdf/manuals/371303l.pdf.  It shows a switch connection a digital input pin to ground.  But also a resistor between the digital input pin and +5V to pull the voltage level back up when the switch is open.  Although I'm not sure that the pull up resistor is truly critical.

Sorry.. here's the VI

can anyone give me a headstart on how to do it using 6211 instead? thanks

[RavensFan]

The 6211 only has 4 digital inputs, while the USB-6008 has 12.  Why would you change cards now?  Although you could connect your switch between a voltage source and an analog input and measure the analog voltage to essentially turn it into a digital input.

What more information do you need?  Have you looked at the DAQmx examples in the example finder yet?

[Flibbertygibbet]

well its because I have two DAQs.. I was thinking of using the analog input part of the 6211 for the push button switches, is that possible?

[RavensFan]

Sure.  You will have to wire your switch to +5VDC on one side and the analog input on the other side.  Due an Analog 1 sample read.  If the voltage is >2.5V than the switch is depressed.  If is <2.5V than it is open.  Whether you will need to put in any bias resistors, I just don't know.

[Flibbertygibbet]

thanks for the advice.

[Flibbertygibbet]

I've done the hardware part, can someone give me a headstart or give me clues on how to start the programming part please? I'm using two 6008 DAQs, 1 for the switches and 1 to light up the LEDs..

Look in the example finder for numerous examples using DAQmx.
