Overview
========
The Simple PWM Interrupt project is to demonstrate usage of the SDK CTimer driver as a PWM with interrupt callback functions
In this example an IO pin connected to the LED is used as a PWM output line to generate a PWM signal.
With an interrupt callback the PWM duty cycle is changed frequently in such a way that the LED brightness can be varied.

Toolchain supported
===================
- IAR embedded Workbench  8.32.3
- Keil MDK  5.27
- MCUXpresso  11.0.0
- GCC ARM Embedded  8.2.1

Hardware requirements
=====================
- Mini/micro USB cable
- LPCLPCXpresso54102 board
- Personal Computer

Board settings
==============
No special settings are required.

Prepare the Demo
================
1.  Connect a micro USB cable between the PC host and the CMSIS DAP USB port (J6) on the board
2.  Open a serial terminal with the following settings (See Appendix A in Getting started guide for description how to determine serial port number):
    - 115200 baud rate
    - 8 data bits
    - No parity
    - One stop bit
    - No flow control
3.  Download the program to the target board.
4.  Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.

Running the demo
================
The log below shows example output of the CTimer simple PWM demo using interrupts in the terminal window:

- You will find a change in LED RED brightness.
- Probe oscilloscope at J1-12 to see output signal.
