Overview
========
The lpuart_interrupt Example project is to demonstrate usage of the KSDK lpuart driver.
In the example, you can send characters to the console back and they will be printed out onto console
 in a group of 8 characters.

Toolchain supported
===================
- IAR embedded Workbench 7.50.1
- Keil MDK 5.17
- GCC ARM Embedded 2015-4.9-q3
- Kinetis Development Studio IDE 3.0.0
- Atollic TrueSTUDIO 5.4.0

Hardware requirements
=====================
- Mini USB cable
- FRDM-KL27Z board
- Personal Computer

Board settings
==============
No special is needed.

Prepare the Demo
================
1.  Connect a mini USB cable between the PC host and the OpenSDA USB port on the board.
2.  Open a serial terminal on PC for OpenSDA serial device with these settings:
    - 115200 baud rate
    - 8 data bits
    - No parity
    - One stop bit
    - No flow control
3.  Download the program to the target board.
4.  Reset the SoC and run the project.
