## Overview
-----------
This demo shows how to use the USART clock output in synchronous and master mode to 
generate a 50% duty of PWM at the frequency got from an odd number of divider. And
the PWM signal is continuous without software interfering.

## Software Setup
---------------------
- copy the folder "usart_pwm" under the path [LPCXpresso802 SDK]\boards\lpcxpresso802\demo_apps 

## Toolchain Supported
---------------------
- Keil MDK 5.27

## Hardware Requirements
------------------------
- Micro USB cable
- LPCXpresso802 board
- Personal Computer
- A oscillograph

## Board Settings
------------------------
No special settings are required.

## Run the Project
------------------------
Run the example by performing the following steps after software and hardware set up:

1. Connect a micro USB cable between the PC host and the CMSIS DAP port(J4 on the 
   LPCXpresso802 board).

2. Compile and download the program to the target board.

3. Run the project.

4. Capture the PWM output signal with a oscillograph.

## Expected Result
------------------------
See the PWM waveform with 1.8Mhz of frequency and 50% of duty on the screen of the oscillograph.
