I am working on extending an existing arduino projec to use a LabVIEW interface.I have a laser gun zombie shooting range that is currently running off of an Arduino. I would like to extend it to use LabVIEW so that I can have simpler control over targets and timing as well as providing a better user score feed and timer feedback for the game. Here's the catch:I didn't have enough digital IO to read in all of my targets and to turn all of my targets on and off I had to extend them with shift registers. The approach worked great with just the arduino but I am afraid that if I try to do the same with LavVIEW, I will suffer speed issues on my polling and writing of the outputs.I'm wondering if anybody has already modifed the firmware to set it up so that the Arduino still pulses the shift register and applies the data out from a buffer and reads the data in to a buffer and then just ship the buffer up to/from LabVIEW.Hopefully this made sense!If nobody has done it yet; I'm going to pioneer it. Any ideas or advice will be fielded!Thanks! - Mike

Shift Register

Thanks for your quick response. I have modified my code and it looks good on the oscilloscope. I just need to modify a harness so I can test it on the device.
