Guide to View Touch Tune Data
Overview
This section provides information on how to visualize touch data when a bi-directional connection is enabled in the Touch Configurator.
Project Configuration and Generation
For creating and configuring a project for visualization, please follow the steps in the "Generate a Touch Project With MPLAB® Code Configurator (MCC) Melody" page for MPLAB® Code Configurator (MCC) Melody or the "Generate a Touch Project With MPLAB® Code Configurator (MCC) Harmony" page for MCC Harmony.
After the creation and configuration of the sensors, navigate to the Tune tab in the Touch Configurator, enable the Touch Tuning Data connection, and select Touch Tuning as the option.
Data Visualization
Open the MPLAB Data Visualizer plugin/standalone and follow the steps given below for Touch visualization and tuning.
The three main sections for data visualization are:
- Connection
- Configuration
- Graph
Section I: Connection
Set up the Baud rate.
Once the window is open, go to the Connections tab and select the correct COM port. In COM settings, select the gear icon and set the Baud Rate required for the project.
Select the Touch COM port.
In the Touch section, select the correct COM port from the dropdown as the data source.
Start the streaming on the COM port first. Then start the streaming on the Touch section.
Section II: Configuration
Select the parameters.
Select any one of the listed options except Output Data. In this case, Sensor Node Parameters is selected.
Modification of parameters.
Under the Sensor Node Config tab, select and modify any one of the parameters in the table.
Write to the kit.
Once the required parameters are changed, the Write to kit button's color changes to yellow. Then click on the Write to kit button. If the write is successful, the button's color will change to green, indicating success. Otherwise, it will change to red, indicating an error with the kit.
Read from the kit.
Click on Read from kit to retrieve the configuration from the kit.
Section III: Graph
For Capacitive Voltage Divide (CVD) devices, the graph is automatically populated for deviation and pressed parameters for the sensors.
For Peripheral Touch Controller (PTC) devices, the graph is automatically populated for state and delta parameters for the sensors.
