It can be difficult to troubleshoot data on an embedded target while your application is running. In the same way a debugger helps you debug your application code, MPLAB Data Visualizer helps you debug your data. With MPLAB Data Visualizer, you can see how key data points in your application change during runtime, e.g. visualize values captured by a sensor on your development board.

To install MPLAB-Data-Visualizer-Standalone(macOS), download this package and open it in IDE.

Release Notes for MPLAB® Data Visualizer
MPLAB Data Visualizer v1.3.1331

March 27, 2023

It can be difficult to troubleshoot data on an embedded target while your application is running. In the same way a debugger helps you debug your application code, MPLAB Data Visualizer helps you debug your data. With MPLAB Data Visualizer, you can see how key data points in your application change during runtime, e.g. visualize values captured by a sensor on your development board.

MPLAB Data Visualizer has the following features:

-Capture data streamed from a running embedded target via serial port (CDC) or the Data Gateway Interface (DGI)
-Concurrently stream data and debug target code using the MPLAB®X IDE
-Decode data fields at runtime using the Data Stream (DS) Protocol format
-Automatically load Data Stream and Dashboard configuration for the DS data stream
-Stream and modify global variables using the run-time configurable Data Visualizer Run Time (DVRT) protocol.
-Visualize the raw or decoded data in a Graph as a time series or display the data in a terminal
-Analyze plotted data using cursors to measure bandwidth, pulse width and more
-Save a snapshot of plotted data as CSV or JSON
-Visualize and analyze power consumption on supported platforms
-Visualize sampled PC values while debugging on supported platforms
-Monitor data for or input data to an application using a custom dashboard

MPLAB Data Visualizer comes as a stand-alone application and as a plug-in to MPLAB X.

System requirements

Like the MPLAB®X IDE, the MPLAB Data Visualizer is based on the NetBeans Platform. Thus it has similar runtime requirements. The minimum platforms are:

-Windows 10 Professional
-Ubuntu® 18.04 or similar.
-macOS® 10.14 Mojave

For all platforms a minimum of 8 GB RAM is recommended.

The MPLAB Data Visualizer v1.3.1331 plug-in must be installed in MPLAB X version 6.05 or later for correct operation.

Hardware tool support

MPLAB Data Visualizer supports targets that stream data over a (virtual) COM port, as well as tools implementing the Data Gateway Interface (DGI) USB interface.

When using a COM port, any target or board can be supported, also user-specific boards. The DGI interface is supported by the Microchip Curiosity Nano and Xplained Pro platforms, as well as the Microchip Power Debugger and Atmel-ICE.

In order to ensure the best possible user experience, make sure that kits or tools used with the MPLAB Data Visualizer are updated to the most recent firmware version.


Documentation is shipped with the product and can be opened from the Data Visualizer User Interface once started.


The latest version of the standalone MPLAB Data Visualizer can be downloaded from the landing page at https://microchip.com/mplab/mplab-data-visualizer. After downloading the installer, start the installation and follow the instructions in the installer.

The plugin version for MPLAB X can be installed and updated from the plugin center in MPLAB X (Tools Menu -> Plugins). This is the recommended approach. It is also possible to download a plugin bundle from the Microchip Gallery, if installing the plugin without an internet connection is required. Unzip the bundle and point to the embedded updates.xml file from the MPLAB X plugin center settings.

Special Considerations

To get the expected result when streaming data, it is important to configure the target system properly. Study the user guide of the target development board or tool carefully as it can contain important information.

When streaming timestamped data over DGI from an Xplained Pro or Curiosity Nano kit, too high data rates can lead to buffer overflows and reduced stability of operation. This also applies to Debug GPIO and Power Data. The Data Visualizer UI will display a warning when the kit or tool indicates a buffer overflow condition. The sample rate at which buffer overflows are likely to occur depends on the PC and the system load. For GPIO it could be down to a few kHz sample rate at system load. For other interfaces it is typically higher.

The standalone MPLAB Data Visualizer may interrupt an active debug session on a development kit on start up. If a debug session is in progress in MPLAB X on a DGI-enabled kit when MPLAB Data Visualizer standalone is started, the debug session may be interrupted and the kit might not show up as a connection in the standalone version. The workaround is to close MPLAB X and unplug and plug in the kit. For simultaneous debugging and data visualization, please use the MPLAB X plugin version of MPLAB Data Visualizer (Window menu > Debugging > Data Visualizer).

If DGI-enabled kits or tools are not detected at all, the following procedure can be tried in order to force a reinstall of the DGI device on a Windows system.

  -Unplug all kits from the Windows machine
  -Right-click the Start button and select 'Device Manager'
  -Select the View menu and turn on Show Hidden Devices
  -Expand the node "Microchip Tools" which lists Data Gateway (DGI) capable devices
  -Right-click the entry for the device you want to uninstall, go to properties, Driver tab and click on Uninstall
  -On the Confirm Device Removal dialog box, if you wish to remove the driver package in addition to uninstalling the device, select the Delete the driver software for this device option
  -When ready to complete the operation, select OK

Known Issues

SSR Description Environment
DV-806 Plotted data can look distorted at certain zoom levels. This happens because the Visualizer reduces the resolution of old data as internal buffers fill up, in order to save memory. Workaround: Pause data streaming while investigating data.

All platforms
DV-835 Cannot connect to ttyACM0 for streaming data. Workaround: add your user to the dialout group and log out, then log back in.

DV-1085 Kit DGI sources will not be listed if the kit is already connected in another process. Workaround: Close the other application and restart MPLAB X or MPLAB Data Visualizer.

macOS, Windows
DV-1089 When renaming a variable streamer field and the field is plotted, the plot source is disconnected. Reconnect the plot source by selecting the new name in the plot options.

All platforms
DV-1176 Interface configuration is not applied after DGI overflow. To ensure correct operation after overflow, reconnect DGI.

All platforms
DV-1335 In the plugin, when the Data Visualizer tab is maximized it will cover floating windows. A workaround is to dock the floating window.

Win 10
MPLAB X 5.40
DV-1652 The calculated average values and the total charge and energy values displayed in the power analysis panel in the graph are based on data points displayed, and can vary slightly depending on the zoom level. Zooming in will give better accuracy as more data points are used for the calculations.

All platforms
DV-1670 On a loaded system, streaming on DGI can fail when the PC cannot read data from the debugger fast enough. This can apply to all interfaces including Power and GPIO. See the Special Consideration section for more info.

All platforms
DV-1671 The calibrate button on the DGI power interface panel can be clicked while calibration is in progress. Clicking it will not have any effect. The calibration will run to completion before a message is displayed.

All platforms
DV-1673 Clicking the Plot All Sources button on a DGI power source in the connections panel will add plots to axes based on unit, instead of to the selected data axis. If other arrangements are desired, add the power sources as plots manually.

All platforms
DV-1683 If a popup dialog overflows the Data Visualizer window, a scroll bar is displayed. Clicking the scroll bar will close the dialog. Use the mouse wheel or tab through the controls in order to scroll the dialog.

All platforms
DV-1711 On Linux, ending an MPLAB debug session can end a concurrent streaming session on the same tool.

DV-1864 Transparency and z-order settings are ignored when importing elements from an existing Atmel Data Visualizer dashboard. The rendering order used will be the order of the elements as specified in the imported .db file.
DV-2012 The Debugger Polling interface, used for PC sampling, can be present for debuggers and kits that support DGI, irrespective of whether a debug session is started or the currently debugged device supports the feature. However, PC sampling is supported only for SAM devices and newer AVR device families.
