9 Data Visualizer Setup

9.1 Data Visualizer Setup Printf and Debug GPIO

The image below shows the ADCC Basic Printf example running, using the MPLAB Data Visualizer.

  1. Click the icon to open the MPLAB Data Visualizer.
  2. Under Debug GPIO, click the icon, to add to the time plot.
  3. Under the COMx port, associated with your board, click the icon to set the baud rate to 115200.
  4. Then click the icon to display text from the COMx port on the terminal.

When using the MPLAB Data Visualizer Time Plot to run the ADCC Basic Printf example, the following will appear:

9.2 Data Visualizer Setup for MCC Melody Data Streamer

When using the MCC Melody Data Streamer Library, this section describes the steps needed to set up the Data Streamer and plot the selected application variables.
Note: These steps will come after configuring the appropriate components in MCC Melody and clicking to generate code.
Figure 9-1. An example application using the MCC Melody Data Streamer Library

As part of the MCC Melody configuration, application variables to be plotted must be added to the Data Streamer Table, giving each a Variable Name and corresponding Variable Type. Once done, this will look similar to examples 2 and 3 from the ADC Example Component.

  1. Within MPLAB X click the icon to open the MPLAB Data Visualizer.
  2. Under the Variable Streamers tab (on the left-hand side), click the button to import a .ds file.
  3. From your project root, navigate into mcc_generated_files/data_streamer/ directory.
  4. Click the data_streamer.ds file to select it.
  5. Then click the button to load the ds file.

Data Visualizer Configuration

Tip: Load the MCC generated data_streamer.ds, meaning the Data Streamer variable configuration file, as follows:

The results when plotting the respective examples are shown below:
