Making a Serial Connection
The Serial Connection Manager
MegunoLink can receive data from many serial ports, Ethernet UDP ports and XBee devices. The Connection Manager is used to manage the active connections.
Open a Connection Manager by selecting it from the visualizer tool, Visualizers docker, or start page. By default, you will see a single serial connection. You can change the port and baud rate of the connection. Make sure that the baud rate selected matches the value set when your Arduino program calls
Serial.begin(9600). The most common value is 9,600 baud.
Connect to the port by clicking the
Each serial connection has a name: Arduino Uno, in the screenshot above. It is especially useful to help you remember what is connected to each port if you have many serial devices connected. If you were working on a wireless project, for example, you could have one connection to the transmitter and one to the receiver. To add additional connections, click on the
Add Connection button on the connection manager’s toolbar.
Check out the main documentation page for more information about the Connection Manger, including making connections to Ethernet/UDP and XBee devices.
Connecting a Visualizer to a Serial Source
Visualizers — such as monitors, plots and tables — take data received by a serial connection and present it in different forms. The simplest visualizer is a Monitor, which shows the raw data received by MegunoLink.
Open a Monitor visualizer using the menu on the main toolbar, the start page, or the Visualizers window docked to the right side of the MegunoLink window.
Select the connection used by the Monitor, or any visualizer, by clicking on the arrow at the end of the
Connection Selector on the toolbar of any visualizer. Select the connection you want from the menu. You can also connect and disconnect from the selected port by clicking on the
Connection Selector button.
Each serial connection can be used by any of the other visualizers. You don’t need to create a separate connection for each visualizer. This lets you quickly change the physical COM port a connection uses without updating each visualizer separately.
