I am trying to write a LabVIEW interface to program some digital chips using their SPI interface and am running into interface problems. Ideally, I would like to be able to create a 16x16 pushbutton matrix and somehow turn that into an array then my plan is to use a case statement and a for loop to read each of the values and send them out, at this point, I'm stuck on making an efficient 16x16 boolean interface, however. Any information would be greatly appreceated.
