Host-board connection

Use the host-board connection parameters to set the serial communication port and baud rate between your Arduino® board and your host computer.

Application download

Use the parameters in this section to select the upload type and set the serial communication port and baud rate between your Arduino board and host computer to deploy a Simulink® model on your Arduino hardware.

Depending on your application and requirements, you can set the upload type for your Simulink model on your Arduino board to USB, OTA Setup, or OTA Upload and configure the dependent parameters in the Configuration Parameters dialog box accordingly.

These parameters are enabled in the Configuration Parameters dialog box when you set Select upload method to USB.
