    Syntax

    writebinblock(v,data,datatype)
    writebinblock(v,data,datatype,header)

    Description

    writebinblock(v,data,datatype) writes a binblock of data in the form specified by datatype to the VISA resource v. The function suspends MATLAB® execution until the specified values are written to the remote host.

    example

    writebinblock(v,data,datatype,header) prefixes the ASCII string specified by header to the data that is sent.

    Create a connection to a VISA resource. This example shows a connection to a device with the alias COM4 using the VISA-Serial interface.

    v = visadev("COM4");

    Write the values [1,2,3,4,5] as a binblock in double format to the VISA resource v.

    writebinblock(v,1:5,"double")

    Define a VISA connection and header string.

    v = visadev("COM4");
hdr = "MEMTEST 8-BIT";

    Write the header and data values [1,2,3,4,5] as a binblock in uint8 format to the VISA resource v.

    writebinblock(v,1:5,"uint8",hdr)

    Input Arguments

    VISA resource, specified as a visadev object.

    Example: writebinblock(v,1:5,"uint8") writes a binblock of data to the VISA resource v.

    Numeric or ASCII data, specified as a 1-by-N vector of numeric values, a character vector, or string of text. For all numeric datatype types, data is a row vector of values.

    Example: writebinblock(v,1:5,"uint8") writes the values [1,2,3,4,5].

    Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | char | string

    Size and format of each value, specified as a character vector or string. datatype determines the number of bytes to write for each value and the interpretation of those bytes as a MATLAB data type.

    Example: writebinblock(v,1:5,"double") writes the values [1,2,3,4,5] as double data.

    Data Types: char | string

    ASCII string prefixed to the data, specified as a string or character vector.

    Example: writebinblock(v,1:5,"double","Test 34.1") writes the header string "Test 34.1" followed by the values [1,2,3,4,5] as double data.

    Data Types: char | string
