MPLAB-Data-Visualizer-Standalone(macOS)

1.3.1113

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.

Supported Products: MPLAB X

Release Notes

MPLAB® Data Visualizer v1.3.1113
October 27th, 2021

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 Protocol format
- Automatically load Data Stream and Dashboard configuration for the data stream
- 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
- 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

The MPLAB Data Visualizer plug-in must be installed in MPLAB X version 5.50 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

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

v1.3:
- Create a user interface for your application using custom dashboards
- Support for Data Stream Protocol auto configuration

v1.2.956:
- Visualize power consumption on supported platforms
- Inspect maximum, minimum and average power consumption over time
- Open visualizer workspace files directly from the MPLAB environment (MPLAB X 5.50 required)

A compatibility update, v1.02, was also made for the Machine Learning Plugin. v1.02 is required for uploading data directly to machine learning partners after this update.

v1.2:
- Save a snapshot of plotted signals to disk as CSV or JSON values
- Plot two-dimensional data sets in the new XY Graph panel
- Connect to Machine Learning partners using the separately installable Machine Learning plugin

v1.1:
- Quick actions for plotting data or viewing data in the terminal
- Choose whether to plot Variable Streamer fields on same or separate axes
- Simplified data stream protocol configuration
  - Fewer steps means its easier to start visualizing multiple variables
- Graph enhancements
  - Plot several signals on the same axis for easy alignment and zoom
  - Organize axes on different rows, resize, and position
  - Inspect values of data points
  - Use cursors to measure signal width, frequency, and duty cycle
- Notable fixed issues
  - Under heavy system load data timestamps could drift so that data plots appeared delayed compared to actual events (DV-1280).
  - Deleting a field/variable in the plot wizard before a name was assigned could crash the application (DV-1265).
  - When streaming data on serial port, data could be timestamped so that parts of plots looked stretched or compressed (DV-1186)

v1.0.681:
- Compatibility fix for MPLAB X IDE v5.40
- Symptoms: No kits show up in connections view and an exception is thrown at startup or on kit connection event.

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 dependens 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).

On macOS Catalina and above, access to protected folders such as Desktop, Documents, and Downloads can be blocked. Follow these steps to enable access:

1. Open System Preferences
2. Open Security & Privacy
3. Open the Privacy tab
4. Select the Full Disk Access category from the list on the left
5. Click the lock button to unlock it
6. Click the + button
7. Hit cmd + shift + g to open the Go To Path dialog
8. Type in /bin/sh
9. Click Open
10. Click the lock button to commit the changes
11. Restart MPLAB X IDE

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.

Linux
DV-1085 A kit's DGI sources won't 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.

Linux
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.
