Arduino programme is made up of lines of codes but when we interface LabVIEW with Arduino, lines of codes are reduced into a pictorial program, which is easy to understand and execution time is reduced into half.

To interface LabVIEW with Arduino, you require the following software’s and hardware’s, Now in this article we learn about How to Interface LabVIEW with Arduino Board. Note that pulling too much current from the charge-pump terminals of IC 1, V+ and V-, can cause these rails to droop and can pull the IC's RS-232 transmission levels out of specification.Ī similar version of this article appeared in the Septemissue of EDN.In previous article of Getting Started with LabVIEW, we have seen about LabVIEW and how it can be graphically programmed and executed in computer (software level). Each transceiver's charge pump requires four small capacitors (not shown), whose values depend on the V DD range but do not exceed 0.47♟. The multiplexer handles rail-to-rail signals, so obtaining its power from IC 1 ensures that RS-232 signals pass directly through, regardless of amplitude. IC 2 receives its power directly from the V+ and V- terminals of IC 1, whose ±5.5V outputs come from an internal charge pump. The circuit's supply-voltage range (3V to 5.5V) makes it compatible with 3V and 5V logic.

One UART and one multiplexer enable one RS-232 transceiver to communicate with four others. Pulldown resistors inside the remote transceivers force the outputs of unselected receivers to a known state.

Selecting Channel 1, for instance, enables IC 1 to communicate with IC 3 without being loaded by IC 4 to IC 6. The table that follows defines the channel-selection codes. The dual four-to-one multiplexer permits transceiver IC 1 to form a network with the four remote transceivers IC 3 to IC 6. The multiplexer in the figure below, IC 2, allows multiple channels (four, in this case) to share a single UART. RS-232 communications with one ♜ and more than one remote system can be problematic, because most ♜s contain only one UART, which provides an interface between synchronous and asynchronous ports.
