High Impedance in LabVIEW FPGA

[troy.perales]

Is there anyway to distinguish an unconnected input from a Boolean False in LabVIEW FPGA? I've tried using " if (input = 'Z') ... " in an HDL Interface Node and not connecting anything to the input, but LabVIEW executes as if the input was '0'.

Any suggestions if this doesn't work?

Hi Troy,

Thanks for coming to the forums with your question. I tried the HDL node and it will not let you not wire in an input or it gives you a broken run arrow. Could you elaborate exactly what you were doing with the HDL node? Also could you elaborate on why need to detect that nothing is on an input? Maybe we could help you find a work around.
