    Writes to memory available on the FPGA target.

    datatype_icon

    reference in

    Reference to the memory item.

    datatype_icon

    address

    Location to write data in memory on the FPGA target.

    The valid address range depends on the requested number of elements you specify when creating the input memory item. For example, if you specify a requested number of elements of 65536, the valid address range is 0–65535. If address exceeds the address range, this node returns an error.

    datatype_icon

    data

    Data to write to the memory on the FPGA target.

    If the input memory item was configured as read-only, this node does not write the data to the memory.

    datatype_icon

    error in

    Error conditions that occur before this node runs.

    The node responds to this input according to standard error behavior.

    Standard Error Behavior

    Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

    error in does not contain an error error in contains an error
    If no error occurred before the node runs, the node begins execution normally.

    If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

    If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

    Default: No error

    datatype_icon

    reference out

    Reference to the memory item.

    datatype_icon

    error out

    Error information.

    The node produces this output according to standard error behavior.

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: All devices

    Web Server: Not supported in VIs that run in a web application
