Serial Write

Write data to the serial device

  • Library:
  • Simulink Support Package for Raspberry Pi Hardware

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.

Parameters

expand all

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

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.

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

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.

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