Serial Tx and Rx Pins
Transmitter and receiver Arduino pins for serial communication
Since R2023a
Model Configuration Pane: Hardware Implementation / Hardware board settings / Target hardware resources / Serial port properties
Description
Set the serial port transmitter and receiver pin numbers of your Arduino® board.
For every serial port, you can individually configure the baud rate and data frame configuration. However, not all Arduino boards support all serial ports. This table lists the serial ports supported by different Arduino boards. Set the Hardware board parameter in the Configuration Parameters dialog box to any one of these boards to enable the serial port.
