Finding the serial port being used.</em> </p> - <h4>Blinking LED</h4> - <p>As a first exercise, you are going to reproduce with OpenModelicaEmbedded the blinking LED example. You can either open the prebuilt example (OpenModelicaEmbedded.Examples.BlinkLed) or build it by yourself. To build the model, locate the components:</p> - <ul> - <li>OpenModelicaEmbedded.Pins.DigitalOutput</li> - <li>OpenModelicaEmbedded.Boards.Arduino</li> - <li>Modelica.Blocks.Sources.BooleanPulse</li> - </ul> - <p>Connect the components as in Figure 3. One thing to notice is that the DigitalOutput model is connected to the Arduino component to specify that the pin belongs to that board. This connection is necessary because OpenModelicaEmbedded can use multiple boards with multiple pins at the same time.</p> - <p><img src=\"modelica://OpenModelicaEmbedded/Resources/Images/BlinkingLEDModel.png\" alt=\"\" /></p> - <p><em>Figure 3. Diagram of the blinking LED.</em></p> - <p>Next you need to specify the serial port that the board is using. This is done by selecting the Arduino component and showing its parameters. In the parameter view, you can find the Port parameter. Write the port name that you got in the section “Preparing your board”. Important: the name must be have quotation marks as shown in Figure 4.</p> - <p><img src=\"modelica://OpenModelicaEmbedded/Resources/Images/QuotedSerialPort.png\" alt=\"\" /></p> - <p><em>Figure 4. Specifying the serial port name. </em></p> - <p>Now you need to set the pin number that you are going to use in the DigitalOutput component. Usually, the Arduino boards have an LED attached to pin 13. Set that number in the Pin parameter as shown in Figure 5.</p> - <p><img src=\"modelica://OpenModelicaEmbedded/Resources/Images/PinNumber.png\" alt=\"\" /></p> - <p><em>Figure 5.

Press the simulate button and wait to see the results.</p> - <p>The first time you run the model, it is probably simulated so fast that you do not have time to react. The reason is that OpenModelica simulates the model as fast as possible. In order to interact with your models using OpenModelicaEmbedded, it is necessary to synchronize the simulation time with real time. This is done in by using Synchronisation block in ModelicaDeviceDriver library. After simulating the model one time, you need to check in the checkbox “Synchronize with real-time” as shown in Figure 6.</p> - //<p> <img src=\"modelica://OpenModelicaEmbedded/Resources/Images/SynchronizeSetting.png\" alt=\"\" /></p> - //<p><em>Figure 6. Synchronizing your simulation with real time.</em> </p> - //<p>If you are building many models with the OpenModelicaEmbedded library, you should set the “Synchronize with real-time” option as a default simulation setting in SimulationCenter under the menu Tools->Options in the section SimulationCenter->Default Experiment (see Figure 7). </p> - //<p><img src=\"modelica://OpenModelicaEmbedded/Resources/Images/DefaultSynchronize.png\" alt=\"\" /> </p> - //<p><em>Figure 7.

If you want to keep the simulation running continuously, you need to change the stop time to “infinite” as shown in Figure 8.</p> - //<p><img src=\"modelica://OpenModelicaEmbedded/Resources/Images/StopTime.png\" alt=\"\" /></p> - //<p><em>Figure 8. Setting the stop time to infinite.</em></p> - //<p>If you run the simulation again, you should see the LED blinking continuously.</p> - <p>One thing that you may have noticed is that OpenModelicaEmbedded prints status messages in the simulation log (see Figure 9). The first thing it prints is a list of the available ports. In that list, you should see your current port (A). After that, it prints the current port and the speed used (B). Once the port is opened, you receive a notification that the board is initialized (C). Usually the boards report the version of Firmata that you are running. Then you set the sampling interval that the board uses (D). In this example, you can see that you are setting pin 13 to be an output because you have used the DigitalOutput component (E). Finally you will see that the board will send you a list of all the pins available and thier capabilities (F). This list contains the number of the pin and the modes in which it can be used, for example: DigitalInput, DigitalOutput, AnalogInput, AnalogOutput, and Servo.</p> - <p><img src=\"modelica://OpenModelicaEmbedded/Resources/Images/ModelPlugLog-nomarkers.png\" alt=\"\" /></p> - <p><em>Figure 9.

In order to configure, read, and write to the board, ModelPlug uses the Firmata protocol v2.3 (<a href=\"http://www.firmata.org/\">http://www.firmata.org</a>). This protocol allows you to connect not only to Arduinos, but also to many boards compatible with Arduino. Examples of other boards supporting the Firmata protocol are:</p> -<ul> -<li>Teensy Development Board: Using AVR or ARM processors</li> -<li>chipKIT: Using PIC32 processors</li> -</ul> -<p>ModelPlug wraps the functionality of Firmata by providing easy-to-use Modelica models that you can connect in your simulations.</p> -<h4>New in Version 1.2</h4> -<ul> -<li>Allows defining initial values in AnalogInput and DigitalInput Pins</li> -<li>Improved support for Windows 10</li> -</ul> -<h4>Limitations</h4> -<p>ModelPlug requires a board with Firmata Version 2.3 or higher.</p> -<p>Currently ModelPlug does not support sensors that communicate through I2C or SPI with the board.</p> -<p>The minimum synchronization interval is 1 ms; therefore, ModelPlug cannot have a sampling interval smaller than that. The standard Firmata allows a minimum sampling interval of 10 ms.<br /> <br />ModelPlug uses a serial protocol; therefore, the transfer speed is constrained by the serial port speed. This can be problematic when reading or writing too many inputs/outputs with a small sampling interval.</p> -<h4>Links</h4> -<p>Ask questions about SystemModeler and ModelPlug</p> -<p><a href=\"http://community.wolfram.com/\">http://community.wolfram.com</a></p> -<p>Find out how to connect sensors and actuators to the Arduino</p> -<p><a href=\"http://playground.arduino.cc/\">http://playground.arduino.cc</a></p> -<p>Get details about the Firmata protocol</p> -<p><a href=\"http://www.firmata.org/\">http://www.firmata.org</a></p> -<p>The breadboard diagrams were created using Fritzing</p> -<p><a href=\"http://fritzing.org/\">http://fritzing.org</a></p> -<p> </p> -<p> </p> -<p> </p></html>", revisions = ""), version = "1.2", Icon(coordinateSystem( initialScale = 0.1, grid = {5, 5}), graphics = {Rectangle(fillColor = {0, 170, 255}, pattern = LinePattern.None, fillPattern = FillPattern.Solid, extent = {{-100, -100}, {100, 100}}, radius = 25), Text(origin = {-47.5, 55}, extent = {{-42.5, 15}, {137.5, -80}}, textString = "OpenModelica", textStyle = {TextStyle.Bold}), Text(origin = {2.5, -15}, extent = {{-77.5, 15}, {77.5, -15}}, textString = "Embedded", textStyle = {TextStyle.Bold})}), Diagram(coordinateSystem(extent = {{-148.5, -105}, {148.5, 105}}, preserveAspectRatio = true, initialScale = 0.1, grid = {5, 5})), + annotation(preferredView = "info", Diagram(coordinateSystem(extent = {{-148.5, -105}, {148.5, 105}}, preserveAspectRatio = true, initialScale = 0.1, grid = {5, 5})), version = "1.2", Icon(coordinateSystem( initialScale = 0.1, grid = {5, 5}), graphics = {Rectangle(fillColor = {0, 170, 255}, pattern = LinePattern.None, fillPattern = FillPattern.Solid, extent = {{-100, -100}, {100, 100}}, radius = 25), Text(origin = {-47.5, 55}, extent = {{-42.5, 15}, {137.5, -80}}, textString = "OpenModelica", textStyle = {TextStyle.Bold}), Text(origin = {2.5, -15}, extent = {{-77.5, 15}, {77.5, -15}}, textString = "Embedded", textStyle = {TextStyle.Bold})}), Diagram(coordinateSystem(extent = {{-148.5, -105}, {148.5, 105}}, preserveAspectRatio = true, initialScale = 0.1, grid = {5, 5})), uses(Modelica_DeviceDrivers(version = "1.5.0"), Modelica(version = "3.2.2"))); end OpenModelicaEmbedded; |
