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

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
- LPCXpresso54102 board
- Personal Computer

Board settings
==============
To make usart_freertos example work, keep default configuration.

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 following message shows in the terminal if the example runs successfully.
