Overview
========

This document explains the freertos_queue example. This example introduce simple logging mechanism
based on message passing.

Example could be devided in two parts. First part is logger. It contain three tasks:
log_add().....Add new message into the log. Call xQueueSend function to pass new message into
              message queue.
log_init()....Initialize logger (create logging task and message queue log_queue).
log_task()....Task responsible for printing of log output.

Second part is application of this simple logging mechanism. Each of two tasks write_task_1 and
write_task_2 print 5 messages into log.



Toolchain supported
===================
- IAR embedded Workbench  9.20.1
- Keil MDK  5.34
- GCC ARM Embedded  10.2.1
- MCUXpresso  11.4.1

Hardware requirements
=====================
- Mini/micro USB cable
- LPCXpresso55S36 board
- Personal Computer

Board settings
==============

    
Prepare the Demo
================
1.  Connect a micro USB cable between the PC host and the CMSIS DAP USB port (J1) 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
================
After the board is flashed the Tera Term will show debug console output.

Example output:
Log 0: Task1 Message 0
Log 1: Task2 Message 0
Log 2: Task1 Message 1
Log 3: Task2 Message 1
Log 4: Task1 Message 2
Log 5: Task2 Message 2
Log 6: Task1 Message 3
Log 7: Task2 Message 3
Log 8: Task1 Message 4
Log 9: Task2 Message 4
