What is MegunoLink?

MegunoLink helps you make your Arduino projects work. Use it to plot measurements from sensors, send commands to control your Arduino or tabulate data.

MegunoLink provides an easy way to interact with your Arduino project.

MegunoLink connects to your Arduino

You can connect MegunoLink to any Arduino device. Whether you are using a core Arduino board such as the Uno and Mega, have branched out to a 3_rd party device like the ESP32 or Artemis, or built your own board: MegunoLink is good to go.

Use the Connection Manager visualizer to create a connection to your Arduino with:

Serial/USB (baud rates from 300 to 921,600),
TCP client or server,
UDP, or
XBee Series 2 Pro, and more.

You can create connections to many devices at the same time. Or many connections to one device: mix serial and wireless to conquer debugging and communications.

MegunoLink also supports multicast DNS (mDNS). Multicast DNS makes it easier to find your wireless masterpiece without guessing its IP address.

Create and configure serial, UDP, file and XBee connections with the Connection Manager

Plotting with MegunoLink

After Installing our MegunoLink library for Arduino, plotting is easy:

#include "CommandHandler.h"

void setup()
{
  Serial.begin(9600);
}

void loop()
{
  // Create a plot variable
  TimePlot MyPlot;

  // Send a measurement from the first analog channel
  MyPlot.SendData("Sensor", analogRead(0));

  // Wait a little while before making the next measurement
  delay(500);
}

#include "CommandHandler.h"

void setup()

{

Serial.begin(9600);

}

void loop()

{

// Create a plot variable

TimePlot MyPlot;

// Send a measurement from the first analog channel

MyPlot.SendData("Sensor", analogRead(0));

// Wait a little while before making the next measurement

delay(500);

}

You have control of all graph properties. From MegunoLink or your Arduino sketch, set the:

Graph title,
X-axis title,
Y-axis title (left and right),
Series name,
Series colors, line-styles, marker symbols and more.

Use multiple graphs for different data, several axes for measurements on different scales or just put all your data on one plot. Zoom in to take a closer look or export the data to a spreadsheet.

Watch your data come to life with MegunoLink, whether it is travelling by serial cable, wireless ether or carrier pigeon (coming soonish).

Plot example — The graph scrolls automatically to show the latest data when Run mode is turned on.

Single axis time plot — Plot similar measurements on a single axis.

Multiple plots — MegunoLink supports multiple plots to graph unrelated data.

Two axis time plot — Plot different measurements on two different axes

Take Command of your Arduino

Build a custom user interface with our Interface Panel visualizer. Just drag and drop controls then give them commands using the Interface Panel Designer.

Commands are sent to your Arduino as you interact with controls:

click buttons,
drag track bars, or
type in a text box.

They’ll go wirelessly or by cable. However you connect.

And the command handler in our MegunoLink library for Arduino makes processing those commands in your Arduino code a breeze. Well, actually a couple of lines of code…

#include “CommandHandler.h”

CommandHandler<> Cmds;

// Function called when Doit command is received
void Cmd_MyCommand(CommandParameters &p)
{
  Serial.println(F(”Your will is my command”));
}

void setup()
{
  Serial.begin(9600);

  // Register commands
  Cmds.AddCommand(F(”Doit”), Cmd_MyCommand);
}

void loop()
{
  // Process and dispatch commands
  Cmds.Process();
}

#include “CommandHandler.h”

CommandHandler<> Cmds;

// Function called when Doit command is received

void Cmd_MyCommand(CommandParameters &p)

{

Serial.println(F(”Your will is my command”));

}

void setup()

{

Serial.begin(9600);

// Register commands

Cmds.AddCommand(F(”Doit”), Cmd_MyCommand);

}

void loop()

{

// Process and dispatch commands

Cmds.Process();

}

Commands call functions in your Arduino program. They can get parameters from the command and do anything you want, from turning on an LED to launching a spaceship (spaceship sold separately).

Good to go

MegunoLink projects can be packaged into a stand-alone application using Builder (sold separately).

Builder creates a custom installer that bundles core MegunoLink functionality with your MegunoLink project. Add branding and distribute your project to the world.
