# 1.5 CCP Timer Mode

This example demonstrates how to use the CCP module in timer mode to generate periodic interrupt.

## Description

The CCP module in timer mode generates periodic interrupt on 1 second period match. The LED is toggled in the interrupt handler to indicate periodic callback.

pic32ak_gc_curiosity.X | Curiosity Platform Development Board and PIC32AK1216GC41064 General Purpose Dual In-Line Module (DIM)

### Setting up Curiosity Development Board

- Insert the GP DIM on to DIM slot of Curiosity Board
- Connect the PKoB (J24) on the board to the computer using a USB type-C cable
- Connect the logic analyzer to pin 3 (RB3) of XPRO1 Header

## Running the Application

1. Build and program the application project using its IDE
2. On successful execution, LED starts blinking
3. Observe the output on logic analyzer, GPIO pin toggles at 1 HZ frequency
