Send and Receive Serial Data Using Arduino Hardware
This example shows how to use Simulink® Support Package for Arduino® Hardware to send and receive serial data with Arduino hardware.
Supported Hardware
- Arduino Mega 2560
- Arduino Mega ADK
- Arduino Uno
- Arduino Due
- Arduino MKR1000
- Arduino MKR WIFI 1010
- Arduino ZERO
- Arduino Leonardo
Introduction
In this example, the Send and Receive Serial Data Using Arduino Hardware and Send Serial Data to Host Using Arduino Hardware models are used to send and receive serial data. These models use the
Serial Transmit
and Serial Receive
blocks to exchange data.- Send and Receive Serial Data Using Arduino Hardware: In this model, the TX1 pin sends serial data to the RX1 pin of your Arduino hardware. This model is configured to run in External mode. For more information on External mode, see Tune and Monitor Model Running on Arduino Hardware.
- Send Serial Data to Host Using Arduino Hardware: In this model, the Arduino hardware sends data to your computer over the serial port 0 (USB port) of the Arduino hardware. This model is configured to run in Normal mode. In this mode, the model is deployed on the Arduino hardware.
The models provided in this example are preconfigured for the Arduino Mega 2560 board. You can run these models on any of the boards listed in the Supported Hardware section by changing the Hardware board parameter in the Simulink model. For more information on how to change the Hardware board parameter, see the Step 2: Configure the Model for Arduino Hardware section of this example.
Prerequisites
Before you start with this example, we recommend you complete the following:
- Getting Started with Arduino Hardware example
- Communicating with Arduino Hardware example
Required Hardware
To run this example, you must have the following hardware:
Step 1: Connect TX and RX Pins on Arduino Hardware
1. Connect your Arduino board to your computer using the USB cable.
2. Connect the TX1 pin to the RX1 pin of your Arduino hardware. This connection is a loopback connection.
Step 2: Configure the Model for Arduino Hardware
1. Open the Send and Receive Serial Data Using Arduino Hardware model. This model is configured to run in External mode.
2. To configure the model, click the Model Configuration Parameters button on the Simulink toolbar.
3. In the Configurations Parameters dialog box, select Hardware Implementation.
4. From the Hardware board list, select the type of Arduino board that you are using.
5. From the Groups list under Target hardware resources, select Serial port properties.
The Serial 1 baud rate parameter is set to
9600
. In this example, the baud rate of Serial 1 baud rate is set because the TX1 and RX1 pins correspond to the Serial port 1 of the Arduino hardware. If you are using any other serial port pins for communication, specify the baud rate of the corresponding serial port.6. Click Apply. Click OK to close the dialog box.
Step 3: Configure the Blocks in the Simulink Model
Double-click these blocks and verify the parameter values specified in the Block Parameters dialog box.
Note:
- Because the TX1 pin is connected to the RX1 pin, specify the Serial Port parameter of the
Serial Transmit
block and the Port number parameter of theSerial Receive
block as1
. - The Sample time parameter specified in the
Constant
block and theSerial Receive
block must be the same.
Step 4: Run the Model in External Mode
1. On the model toolbar, set Simulation mode to
External
.2. The default Simulation stop time is
10.0
seconds. To run the model for an indefinite period, enter inf
.3. Click Run. The lower left corner of the model window displays status while Simulink prepares, downloads, and runs the model on the hardware.
At each time step, the TX1 pin transmits the data specified in the
Constant
block to the RX1 pin of your Arduino hardware. The RX1 pin receives the data and displays it on the Display Output
block.4. Observe the output in the
Display Output
and Display Status
blocks.5. Disconnect the wire from the RX1 pin. Both the
Display
blocks now output 0
. A value of 0
in the Display Status
block indicates that no data is received at the given time step. If you reconnect the wire again, you can see that the values at the Display
blocks are restored.6. To stop running the model on your hardware, click Stop on the model toolbar.
Step 5: Run the Model in Normal Mode
1. Remove the wire connecting RX1 and TX1 pins because in this model, the data is sent to a serial terminal over the Serial port 0 (USB port).
2. Open the Send Serial Data to Host Using Arduino Hardware model. This model is configured to run in Normal mode.
3. In the Configurations Parameters dialog box, go to Hardware Implementation > Target hardware resources > Groups > Serial port properties. Set Serial 0 baud rate to the maximum baud rate supported by the serial port of your Arduino hardware.
4. Double-click the
Serial Transmit
block and verify these parameter values.5. On the model toolbar, set Simulation mode to
Normal
and click the Deploy to Hardware button. The lower left corner of the model window displays status while Simulink prepares, downloads, and runs the model on the hardware.6. Open the serial terminal in your computer ( for example, Arduino IDE serial monitor). When logging in to the serial terminal:
- Specify the COM port number that corresponds to your serial connection. To learn how to find the COM port number, see Configure Host COM Port.
- Specify the baud rate to the same value as the baud rate set in the Model Configuration Parameters dialog box. In this example, the baud rate is
115200
.
After you login to the serial terminal, you can see that the counter values are displayed with label Counter_val :.
Other Things to Try
- Configure Send and Receive Serial Data Using Arduino Hardware model to exchange data over other serial ports of the Arduino hardware.
- Create a Simulink model that uses
Serial Receive
andSerial Send
blocks from Instrument Control Toolbox to exchange serial data between your computer and Arduino hardware.

How to: Receive Strings From Serial Ports in Visual Basic. 2 minutes to read. Contributors. In this article This topic describes how to use My.Computer.Ports to receive strings from the computer's serial ports in Visual Basic. To receive strings from the serial port. Initialize the return string.
Dim returnStr As String = '. Determine which serial port should provide the strings. This example assumes it is COM1.
Use the My.Computer.Ports.OpenSerialPort method to obtain a reference to the port. For more information, see. The Try.Catch.Finally block allows the application to close the serial port even if it generates an exception. All code that manipulates the serial port should appear within this block. Dim com1 As IO.Ports.SerialPort = Nothing Try com1 = My.Computer.Ports.OpenSerialPort('COM1') com1.ReadTimeout = 10000 Catch ex As TimeoutException returnStr = 'Error: Serial Port read timed out.' Finally If com1 IsNot Nothing Then com1.Close End Try. Create a Do loop for reading lines of text until no more lines are available.
Do Loop. Use the method to read the next available line of text from the serial port. Achtung baby super deluxe. Dim Incoming As String = com1.ReadLine.
Use an If statement to determine if the method returns Nothing (which means no more text is available). If it does return Nothing, exit the Do loop. If Incoming Is Nothing Then Exit Do End If. Add an Else block to the If statement to handle the case if the string is actually read.

The block appends the string from the serial port to the return string. Else returnStr &= Incoming & vbCrLf. Return the string. Return returnStr Example Function ReceiveSerialData As String ' Receive strings from a serial port. Dim returnStr As String = ' Dim com1 As IO.Ports.SerialPort = Nothing Try com1 = My.Computer.Ports.OpenSerialPort('COM1') com1.ReadTimeout = 10000 Do Dim Incoming As String = com1.ReadLine If Incoming Is Nothing Then Exit Do Else returnStr &= Incoming & vbCrLf End If Loop Catch ex As TimeoutException returnStr = 'Error: Serial Port read timed out.' Finally If com1 IsNot Nothing Then com1.Close End Try Return returnStr End Function This code example is also available as an IntelliSense code snippet.

In the code snippet picker, it is located in Connectivity and Networking. For more information, see. Compiling the Code This example assumes the computer is using COM1.
Robust Programming This example assumes the computer is using COM1. For more flexibility, the code should allow the user to select the desired serial port from a list of available ports. For more information, see. This example uses a Try.Catch.Finally block to make sure that the application closes the port and to catch any timeout exceptions. For more information, see.
