Data Monitor and Control Interface (DMCI) Runtime Watch

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

1

Ensure DMCI plugin is installed.

2

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).

3

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.

4

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.

5

Open the DMCI window.

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