*

* The Getting Started example will help new users get familiar with Atmel's
|
* BTstack port for SAM MCUs

* SAM family of microcontrollers. This basic application shows the startup

|
||||||
* The demonstration program makes the LED(s) on the board blink at a fixed rate.
|
*
|
||||||
* This rate is generated by using Time tick timer. The blinking can be stopped
|
* -# Build the program and download it inside the evaluation board.
|
||||||
* using the push button.
|
* -# On the computer, open and configure a terminal application
|
||||||
*
|
* (e.g. HyperTerminal on Microsoft Windows) with these settings:
|
||||||
* \section Usage
|
* - 115200 bauds
|
||||||
*
|
* - 8 bits of data
|
||||||
* -# Build the program and download it inside the evaluation board.
|
* - No parity

* - 1 stop bit

* (e.g. HyperTerminal on Microsoft Windows) with these settings:
|
* - No flow control
