Overview
========
This example is showing data send and receive via FreeRTOS adapted LPUART driver. Program initially send
string into serial terminal via virtual COM. After that, user may send some custom input and
application will return every 4 characters back to console. If delay from last user input exceed
10s (receive timeout) notification about exceeded timeout appear and application will finish.
Example need only single LPUART instance.

Toolchain supported
===================
- IAR embedded Workbench  9.30.1
- Keil MDK  5.37
- GCC ARM Embedded  10.3.1
- MCUXpresso  11.6.0

Hardware requirements
=====================
- Mini/micro USB cable
- EVK-MIMXRT1020 board
- Personal Computer

Board settings
==============
No special settings are required.

Prepare the Demo
================
1.  Connect a USB cable between the host PC and the OpenSDA USB port on the target board.
2.  Open a serial terminal with the following settings:
    - 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
================
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.

Customization options
=====================

Note:
To debug in qspiflash, following steps are needed:
1. Select the flash target and compile.
2. Set the SW8: 1 off 2 off 3 on 4 off, then power on the board and connect USB cable to J23.
3. Start debugging in IDE.
   - Keil: Click "Download (F8)" to program the image to qspiflash first then clicking "Start/Stop Debug Session (Ctrl+F5)" to start debugging.
