Serial Configuration

R2026b

Data frame configuration for serial port communication

Since R2023a

Model Configuration Pane: Hardware Implementation / Hardware board settings / Target hardware resources / Serial port properties

Description

Select the data frame configuration for serial port communication. The first digit indicates the number of bits in each data packet. The second digit indicates the parity bits present in the data packet. The last digit indicates the number of stop bits in each data packet. For example:

  • SERIAL_8N1 indicates 8-bit data communication with no parity bits and one stop bit.

  • SERIAL_7E2 indicates 7-bit data communication with even parity bits and two stop bits.

  • SERIAL_6O2 indicates 6-bit data communication with odd parity bits and two stop bits.

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.
