1.2 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 PIC32MM USB Curiosity board
To run the demo, the following additional hardware are required:
Connect micro USB cable to the 'USB1' connector on the board to the computer
Install an USB UART click board on to the mikroBUS socket J4
Connect the OCM2C pin RB0 (Pin on J12) to the ICM1 pin RA10 (pin on J12)
Connect mini USB cable between PC and the USB UART click board
Running the Application
Open the Terminal application (Ex.:Tera term) on the computer
Connect to the "USB to UART" COM port and configure the serial settings as follows:
Baud : 115200
Data : 8 Bits
Parity : None
Stop : 1 Bit
Flow Control : None
Build and Program the application project using its IDE
Console displays the captured pulse width as shown below:
