Overview
========
The RTC project is a simple demonstration program of the SDK RTC driver. It sets up the RTC
hardware block to trigger an alarm after a user specified time period. The test will set the current
date and time to a predefined value. The alarm will be set with reference to this predefined date
and time.

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/micro USB cable
- FRDM-KL43Z board
- Personal Computer

Board settings
==============
This example project does not call for any special hardware configurations.
Although not required, the recommendation is to leave the development board's jumper settings
and configurations in default state when running this example.

Prepare the Demo
================
1. Connect a USB cable between the PC host and the OpenSDA USB port on the board.
2. Open a serial terminal with these 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 example.

Running the demo
================
When the example runs successfully, you can see the similar information from the terminal as below.
