Data Monitor and Control Interface (DMCI) Runtime Watch

To use the Data Monitor and Control Interface (DMCI) Runtime Watch, follow these steps:


Ensure DMCI plugin is installed.


Select the REAL ICE™ In-Circuit Emulator as the hardware tool for the project.

Open the Project Properties window for the application being debugged. Select the MPLAB® REAL ICE as the hardware tool (Runtime Watch will only work with a REAL ICE debug tool).


Start the debug session.

Start the debug session by clicking on the Debug icon Main_Debug_Project.png. This will cause the project to build, allowing the DMCI plugin to identify all the application variables.


Pause the debug session.

Pause the debug session with either a break point LineBreakpoint.png, halt-on-main, or a manual pause Debug_Pause.png.


Open the DMCI window.

From the main IDE menu select Tools > Embedded > DMCI > DMCI Window.

  • Select the global variable to watch.
  • Check the Runtime Update box.
  • Adjust the refresh rate (optional).
  • Select OK.


Enable Automatic Events.

  • Select the Automated Event Settings icon from the DMCI window.
  • Check the Enable Operation box, then press OK


Continue the simulation session.

Click on the Run icon to continue the simulation and watch the value of the variable update in the graph as the application runs.
