Swaps the high-order 8 bits and the low-order 8 bits for every word in data.

If you want to byte-swap floating-point or fixed-point numbers, use the Type Cast function to cast the value to a 1D array of bytes by wiring an array of numeric controls to the type input and the floating-point or fixed-point numbers to the x input. Then use the Reverse 1D Array function to convert the array to a floating-point number with the elements reversed. The connector pane displays the default data types for this polymorphic function.

Inputs/Outputs

  • cu16.png data —

    data is an integer, an array of integers, or a cluster containing integers that you want to byte swap. If data is a cluster that contains integers, this function swaps only the integer elements of the cluster. Neither refnums or variants are valid inputs. Both will break the input wire.

  • iu16.png byte swapped —

    byte swapped is of the same data type and structure as data.

    • FPGA Module Details

    The following details apply when you use this object in an FPGA VI.

    Note The following details are subject to change with each version of the LabVIEW FPGA Module.
    Single-Cycle Timed Loop Supported.
    Usage You cannot wire a fixed-point data type to this function.
    Timing This function requires no clock cycles to execute because it does not include an internal register.
    Resources This function consumes no FPGA resources because it is purely a wiring operation.
