2. Getting Started
2.1. Xplained Pro Quick Start
Steps to start exploring the Atmel Xplained Pro platform:
1. Download Atmel Studio.
2. Launch Atmel Studio.
3. Connect the DEBUG USB port on the kit to the PC using a USB cable (Standard-A to Micro-B or
Micro-AB).
When the Xplained Pro MCU kit is connected to the computer for the first time, the operating system will
install the software driver. The driver file supports both 32- and 64-bit versions of Microsoft® Windows®
XP, Windows Vista®, Windows 7, Windows 8, Windows 10, and Windows Server 2012.
When the Xplained Pro MCU board is powered, the green power LED will glow and Atmel Studio will
auto-detect the specific Xplained Pro MCU- and extension board(s) that are connected. Atmel Studio will
present relevant information such as datasheets and kit documentation. The kit landing page in Atmel
Studio also has an option to launch the Atmel Software Framework (ASF) example applications for the kit.
The SAM HA1 device is programmed and debugged by the on-board Embedded Debugger and therefore
no external programmer or debugger tool is required.

3. Xplained Pro
Xplained Pro is an evaluation platform that provides the full Atmel microcontroller experience. The
platform consists of a series of Microcontroller (MCU) boards and extension boards, which are integrated
with Atmel Studio, have Atmel Software Framework (ASF) drivers and demo code, support data
streaming, and more. Xplained Pro MCU boards support a wide range of Xplained Pro extension boards,
which are connected through a set of standardized headers and connectors. Each extension board has
an identification (ID) chip to uniquely identify which boards are connected to an Xplained Pro MCU board.
This information is used to present relevant user guides, application notes, datasheets, and example
code through Atmel Studio.
3.1. Embedded Debugger
The SAM HA1G16A Xplained Pro contains the Atmel Embedded Debugger (EDBG) for on-board
debugging. The EDBG is a composite USB device of three interfaces; a debugger, Virtual COM Port, and
a Data Gateway Interface (DGI).
Together with Atmel Studio, the EDBG debugger interface can program and debug the ATSAMHA1G16A.
On SAM HA1G16A Xplained Pro, the SWD interface is connected between the EDBG and the
ATSAMHA1G16A.
The Virtual COM Port is connected to a UART on the ATSAMHA1G16A and provides an easy way to
communicate with the target application through terminal software. It offers variable baud rate, parity, and
stop bit settings. Note that the settings on the ATSAMHA1G16A must match the settings given in the
terminal software.
Info: The Virtual COM Port in the EDBG requires the terminal software to set the data terminal
ready (DTR) signal to enable the UART pins connected to the ATSAMHA1G16A. If the DTR
signal is not enabled the UART pins on the EDBG is kept in high-z (tristate) rendering the COM
port unusable. The DTR signal is set automatically by some terminal software, but it may have
to be manually enabled in your terminal.
The DGI consists of several physical interfaces for communication with the host computer.
Communication over the interfaces is bidirectional. It can be used to send events and values from the
ATSAMHA1G16A or as a generic printf-style data channel. Traffic over the interfaces can be timestamped
on the EDBG for more accurate tracing of events. Note that timestamping imposes an overhead that
reduces maximal throughput. Atmel Data Visualizer is used to send and receive data through DGI.
The EDBG controls two LEDs on SAM HA1G16A Xplained Pro; a power LED and a status LED. The
table below shows how the LEDs are controlled in different operation modes.
Table 3-1. EDBG LED Control
Operation Mode Power LED Status LED
Normal operation Power LED is lit when power is
applied to the board.
Activity indicator, LED flashes
when any communication
happens to the EDBG.
Bootloader mode (idle) The power LED and the status LED blinks simultaneously.
Bootloader mode (firmware
upgrade)
The power LED and the status LED blinks in an alternating pattern.

For further documentation on the EDBG, see the EDBG User Guide.
3.2. Hardware Identification System
All Xplained Pro compatible extension boards have an Atmel ATSHA204 CryptoAuthentication™ chip
mounted. This chip contains information that identifies the extension with its name and some extra data.
When an Xplained Pro extension is connected to an Xplained Pro MCU board the information is read and
sent to Atmel Studio. The Atmel Kits extension, installed with Atmel Studio, will give relevant information,
code examples, and links to relevant documents. The table below shows the data fields stored in the ID
chip with example content.

External HV input 6V to 28V Voltage regulator in SBC
is specified for up to
85mA. This input also
supplies the LIN Bus

The kit will automatically detect which power sources are available and choose which one to use
according to the following priority:
1. External power.
2. Embedded Debugger USB.
3. External HV input
Note: The selection for the supply of the Target MCU has a separate connector. The above priority
selects which supply is used to power the EDBG and the VCC_P3V3_CON.
Info: External power is required when 500mA from a USB connector is not enough to power
the board with possible extension boards.
3.4. Xplained Pro Headers and Connectors
3.4.1. Xplained Pro Standard Extension Header
All Xplained Pro kits have one or more dual row, 20-pin, 100mil extension header. Xplained Pro MCU
boards have male headers, while Xplained Pro extensions have their female counterparts. Note that all
pins are not always connected. All connected pins follow the defined pin-out description in the table
below.
