writebinblock

Write one binblock of data to VISA resource

Since R2021a

Syntax

writebinblock(v,data,datatype)

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.

Examples

Write Binblock of Data to VISA Resource

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")

Input Arguments

v — VISA resource

visadev object

VISA resource, specified as a visadev object.

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

data — Numeric or ASCII data

1-by-N numeric array | character vector | string scalar

Numeric or ASCII data, specified as a 1-by-N vector of numeric values or as a character vector or string scalar 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

datatype — Size and format of each value

"uint8" | "int8" | "uint16" | "int16" | "uint32" | "int32" | "uint64" | "int64" | "single" | "double" | "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
