Overview
========
This SCTIMer project is a demonstration program of the SDK SCTimer driver's PWM generation. It sets up a PWM signal
and periodically updates the PWM signals dutycycle.

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 SCTimer driver PWM demo in the terminal window:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
SCTimer example to output center-aligned PWM signal

You will see a change in LED brightness if an LED is connected to the SCTimer output pin
If no LED is connected to the pin, then probe the signal using an oscilloscope
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- Probe oscilloscope at J2-18 to see output signal.
Customization options
