Overview
========
The UART example for FreeRTOS demonstrates the possibility to use the UART driver in the RTOS.
The example uses single instance of UART IP and writes string into, then reads back chars.
After every 4B received, these are sent back on UART.

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
- USB to TTL converter
- FRDM-KL27Z board
- Personal Computer

Board settings
==============
Connect the USB to TTL converter to FRDM-KL27Z board.
FRDM-KL27Z UART pins:
- TX of USB2COM to J1-7
- RX of USB2COM to J1-5
- GND of USB2COM to J2-14

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

Running the demo
================
You will see the welcome string printed out on the console.
You can send characters to the console back and they will be printed out onto console in a group of 4 characters.
