    Release notes for basic board feature test code for 72MHz kinetis family
		  Freescale Semiconductor February 2012   
********************************************************************************

Demo code runs on the TWR-K20D72M module.

TWR_K20D72M_DEMO runs several basic board test cases on TWR-K20D72M, this includes demos for GPIO, I2C, RTC, ADC, TSI, IRQ, USB Device and Irda. You can type commands in console window and run each demos. Following is the output after board reset.

===========
Basic Setup
===========

TWR-K20D72M setup
----------------
Use default jumper setting for board.

================
Demo explanation
================

1. Download the code to MCU. 

2. Open the P&E Micro Terminal Utility and connect the USB COM at 115200 bps with no parity and 8 bit size.

3. Type commands after "demo>" to try out each demo, and you can press any key to exit the demo, there is one problem with USB device demo, you will not be able to return from that demo by pressing any keys, you need to press reset button on board.
