Hi, my name is Brian Alexander and I am a software engineer at NI. Most of my work has been on driver software for PXI modules including PXIe-5170/5171/5172, PXIe-5163/5164, PXIe-5413/5423/5433. Part of that work has included LabVIEW Instrument Design Libraries; see my tutorial on the Instruction Framework IDL here.
