Idea is quite simple - add to instrument drivers project wizard template for switch/MUX/matrix devices.
Custom switching boards are commonly used, b/c for some simple purposes it is cheaper to make custom design with simple functionality (some micro processor which controls relays), and which could communicate by serial line. Then instrument driver - is ideal solution to create simple API in LabVIEW for its control; but unfortunately, there is no template for such types of devices in New Instrument Driver project wizard.
Any idea that has not received any kudos within a year after posting will be automatically declined.
