Objective
This page provides a basic interrupt exception code example for the PIC32MX MCU. The project configures the Timer 2 period match interrupt event to trigger an ISR that toggles LED LD6 on the development board every 100mS.
The hardware for this project uses the ArduinoTM compatible chipKIT WF-32 board from Digilent Inc.

We recommend extracting the .zip to the following "root" folders:
Windows:
- C:
Linux:
- /home/<username>/MPLABXProjects
Mac OS:
- Users/<username>/MPLABXProjects
You should see an appended sub-folder "/MTT/32bit-mx/code-examples/interrupt-usage" containing the project "interrupt-usage.X"
Procedure
Attach the debugger to the WF-32 board. Power up the board. Start MPLAB X.
