1.3 CCP Capture Mode

This example shows how to use the CCP module in capture mode to measure pulse width of an input signal.

Description

In this application, a pulse signal is generated using the compare mode of CCP peripheral and is fed to the capture input. CCP peripheral captures the time at every edge and displays the pulse width on the serial terminal.

Setting up the hardware

The following table shows the target hardware for the application projects.

Setting up Curiosity Development Board

  • Connect the pin 3 (ICM1 - RB3) of XPRO1 Header to pin 4 (OCM2 - RB9) of XPRO1 Header
  • 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

Running the Application

  1. Open the Terminal application (Ex.:Tera term) on the computer
  2. Connect to the “PICkit 4 On Board Virtual COM Port” and configure the serial settings as follows:
    • Baud : 115200
    • Data : 8 Bits
    • Parity : None
    • Stop : 1 Bit
    • Flow Control : None
  3. Build and Program the application project using its IDE
  4. Console displays the captured pulse width as shown below:
