write(device,data,datatype)
writes the row or column vector data to the specified serial port
connection device. The function writes the data in the specified data
type datatype, regardless of the format in data.
The function suspends MATLAB® execution until the specified values are written.
Serial port connection, specified as a serialport
object.
Example: write(device,1:5,"uint8") writes to the serial port
connection device.
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: write(device,[20:24],"int16") writes the values
[20,21,22,23,24].
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 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. For ASCII text, you can specify datatype
as either "char" or "string".
Example: write(device,1:5,"int16") writes data as int16 data
type.
