MPLAB^® Data Visualizer

Need Help?

Overview

Troubleshooting your code's run-time behavior has never been easier. MPLAB^® Data Visualizer is a free debugging tool that graphically displays run-time variables in an embedded application. Available as a plug-in for MPLAB X Integrated Development Environment (IDE) or a stand-alone debugging tool, it can receive data from various sources such as the Embedded Debugger Data Gateway Interface (DGI) and COM ports. You can also track your application's run-time behavior using a terminal or graph. To get started with visualizing data, check out the Curiosity Nano Development Platform and Xplained Pro Evaluation Kits.

Key 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
Configure the Graph as a rolling time plot or as a simple oscilloscope with egde triggers
Analyze plotted data using cursors to measure bandwidth, pulse width and more
Log data to file as it is being captured, using CSV or compressed Apache Arrow format.
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

*For information on specific DGI features, check the user guide for your board or in MPLAB Data Visualizer when your kit is connected.

Did you know that MPLAB Data Visualizer is now supported in Microsoft^® Visual Studio^® Code (VS Code^®) via our MPLAB Extensions for VS Code? These extensions are currently released under an early access program to allow users to provide us with feedback for additional development.
