Configure Serial Port Communication Settings
- MATLAB & Simulink (2024)
Before you can write or read data, both the serial port object and the instrument must have identical communication settings. Configuring serial port communications involves specifying values for properties that control the baud rate and the Serial Data Format. These properties are as follows.
You create a serial port object with the serialport function. serialport requires the name of the serial port connected to your device and the baud rate as input arguments. You can also configure property values during object creation using name-value pair arguments.
To configure the settings for a serial port, you will need to access the device manager or the BIOS (Basic Input Output System) settings on your computer. Once you have located the serial port, you can adjust the settings such as the baud rate, data bits, parity, and stop bits.
serialportlist or serialportlist("all") returns a list of all serial ports on a system. The list includes virtual serial ports provided by USB-to-serial devices and Bluetooth® Serial Port Profile devices. The list shows all the serial ports you can access on your computer and can use for serial port communication.
To configure the Serial Port for your device, on your computer go to Control Panel - Device Manager, select “High-Speed USB Serial Port (Com X)”, right click and select Properties.Click the Features tab. This tab is used to change the COM port number and configure the port.
Click the Port Settings tab and set the Bits per second parameter. In the Configuration Parameters dialog window, go to Host-board connection. Set Set host COM port to either Manually Select or Manually Specify and update the COM port number and Bootloader COM port to match the ports numbers in Windows.
To connect a device to a serial port, you will need a serial cable that matches the connector on the device. The most common type of serial cable is a 9-pin male-to-male cable. The cable is then connected to the serial port on the computer or device.
To change the COM port settings on a Windows computer go to ' Start ' > ' Control Panel ' > ' Device Manager ' > ' Ports ' > ' Communication Port (COM1) ' At this point right click and choose Properties and go into the Port Settings tab.
Expand the Ports (COM & LPT) section.Right-click the COM port and select Properties.Click the Port Settings tab and click Advanced.Change the COM port number to an available COM port number.
In the Device Manager, expand the Universal Serial Bus Controllers tree. You will see your native COM port listed as Communications Port (COM1). Right-click on Communications Port (COM1) and select Properties.In the Properties window, click on the Port Configuration tab and then click on Port Setting.
