String to ASCII

Convert string signal to uint8 vector

• 

Libraries:
Simulink / String

Description

The String To ASCII block converts a string signal to a uint8 vector. The block converts each character in the string to its corresponding ASCII value. For example, the block converts the input string "Hello" to [72 101 108 108 111].

Ports

Input

Port_1 — Input string signal

scalar

Input string signal, specified as a scalar.

Data Types: string

Output

Port_1 — Converted uint8 vector signal

vector | 1D vector of N elements

Converted uint8 vector signal of ASCII characters from input string signal, specified as a vector. The block converts each element in the string into its ASCII character equivalent and outputs the ASCII equivalents as a vector. If there are fewer characters than the maximum length, the block fills the remaining space with zeros at simulation. At code generation, the block fills the remaining space with null characters.

Data Types: uint8

Parameters

Output vector size — Size of output vector

31 (default) | scalar

Size of output string vector, specified as a scalar.

Programmatic Use

Block Parameter: OutputVectorSize

Type: character vector

Values: scalar

Default: '31'

R2024b: String to ASCII block output dimension change

The String to ASCII block output dimension has changed from a 2D row vector, such as a 2-by-N vector, to a 1D vector, N. N is the number of elements.
