Serial Write

Write data to the serial device

Add-On Required: This feature requires the Simulink Support Package for Raspberry Pi Hardware add-on.

Libraries:
Simulink Support Package for Raspberry Pi Hardware / Communication

Description

Write data to a serial device connected to the Raspberry Pi^® hardware. To open the pin map of the Raspberry Pi board, click the View pin map.

Refer to Asynchronous Serial Communication for information.

Ports

Input

Port_1 — The input port to accept data

[Nx1] or [1xN] array

The input port through which the block accepts data.

Data Types: single | double | int8 | int16 | int32 | uint8 | uint16 | uint32

Parameters

Board — The specific board used for serial communication

Pi 3 Model B (default) | Model B Rev1 | Model B Rev2 | Model B+ | Pi 2 Model B | Pi 3 Model B+ | Pi Zero W | Pi 4 Model B | Pi 5 Model

Select the specific board that you are using. Changing the board updates the pin choices that you get.

Port — The port at which you want to connect to the serial device

/dev/ttyAMA0 (default)

The port to which to you want to connect from the selected Raspberry Pi board to the serial device. For Pi 3 Model B board, the default serial port is /dev/ttyS0.

Baudrate (in bits/s) — Bits per second

9600 (default) | 50 | 75 | 110 | 134 | 150 | 200 | 300 | 600 | 1200 | 1800 | 2400 | 4800 | 9600 | 19200 | 38400 | 57600 | 115200 | 230400

Select the rate at which the data is read over the serial line. The baud rate is measured as the number of bits read per second.

Parity — Even parity or the odd parity added to the data

None (default) | Even | Odd

Select the parity added to the data transmitted. A parity bit is used to detect error in data transmission.

• None – None value in this parameter means that no parity is used for error detection in the data transmission.

• Even parity – The parity bit value is 1, if the number of bits with value as 1 is odd. The parity bit value is 0, if the number of bits with value as 1 is even.

• Odd parity – The parity bit value is 1, if the number of bits with value as 1 is even. The parity bit value is 0, if the number of bits with value as 1 is odd.

Stop bits — The bit used as the stop bit

1 (default) | 2

Select the bit used as the stop bit in the data transmission. A stop bit marks the end of a unit of transmission.
