ASCII to String

Uint8 vector signal to string signal

• 

ASCII to String block

To add a block to a model, double-click the canvas and start typing the block name. Then, select the block from the list.

Libraries:
Simulink / String

Description

The ASCII to String block converts uint8 vector signals to string signals. The block treats each element in the input vector as an ASCII value during the conversion. For example, the block converts an input vector of [72 101 108 108 111] to the string "Hello".

Ports

Input

Port_1 — ASCII signal

vector

ASCII signal, specified as a vector.

While using dynamic strings, if the length of the input vector exceeds the number of characters specified in the configuration parameter Buffer size of dynamically-sized string (bytes) (256 by default), the ASCII to String block truncates the string output to the buffer size-1 (for example, 255), for generated code. To avoid truncation, increase the value of the Buffer size of dynamically-sized string (bytes) configuration parameter.

Example: [088 099]

Data Types: uint8

Output

Port_1 — Converted string signal

scalar

Converted string signal from input ASCII signal, specified as a scalar. The block converts each ASCII element in the vector into its alphanumeric equivalent and outputs all elements concatenated into one string.

Data Types: string

Block Characteristics

Data Types	integer | string
Direct Feedthrough	yes
Multidimensional Signals	no
Variable-Size Signals	no
Zero-Crossing Detection	no

Programmatic Use: Add Block

To add the block programmatically, use the add_block function with one of these library block paths as the source.

"simulink/String/ASCII to String"

Example: add_block("simulink/String/ASCII to String","myModel/myBlock",MakeNameUnique="on")
