What is a serial terminal program pro#
This requires the MegunoLink Arduino Library to handle received commands.ĭownload MegunoLink Pro and test the Interface Panel with your own projects.

The complete source for the Blink 2.0 program, including the MegunoLink Pro project with the interface panel all ready to go, is available from GitHub. Pressing the buttons will display the set values in the serial monitor. Then, from the MegunoLink Pro visualizer, the blink rate and duration of the LEDs can be set by typing values into the controls. This updates the Interface Panel visualizer with the new design. Hit the Apply button when the interface design is ready for testing. multiplication (*), division (/), modulus (%).MegunoLink Pro uses the DynamicExpresso library to parse expressions. For example, if seconds were used for the value in the Interval control, instead of milliseconds, an expression could be used to convert from seconds to milliseconds when the message is sent: It is also possible to include simple expressions between the brackets when referring to controls. So you’ll be able to change the blink rate, simply by entering the desired interval into the control and hitting enter. The text will be replaced with the value from the Interval numeric control when the command is sent. To have MegunoLink Pro use the value from the Interval control in place of the fixed number, set the command text to: This would set the time between blinks to 1000 millisecond (1 second). Making a selection from the menu inserts the appropriate text into the serial command to include the control’s value when the command is sent.įor example, the blinking interval for Blink 2.0 is set using a command like:

Click the Test button to see what will be sent when the action occurs.Ī button to the right of the command text shows a menu of the available controls, and the value available from each. Special characters, such as carriage returns (\r), newlines (\n) and tabs (\t) can be added using escape codes. Use the command editor to include control values in command messages, or edit long commands. This short video shows the interface panel being built (3 minutes): We also added buttons which send commands to the Arduino to print the current settings, and we use a label control for the title text. The control named Interval sets the time between blinking the length of the flash is set a control named Duration. A numeric up/down control is used for each parameter. The interface lets you control two parameters through MegunoLink Pro: how fast the LED blinks and how long it remains on for each blink. We built a simple user interface for a program to blink the LED built-in to most Arduino boards.
