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 that 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 that are connected through
a set of standardized headers and connectors. Each extension board has an identification (ID) chip to uniquely
identify which boards are mounted on a Xplained Pro MCU board. This information is used to present relevant
user guides, application notes, datasheets and example code through Atmel Studio. Available Xplained Pro
MCU and extension boards can be purchased in the
Embedded Debugger
The SAM4S Xplained Pro contains the Atmel® Embedded Debugger (EDBG) for on-board debugging. The
EDBG is a composite USB device of 3 interfaces; a debugger, Virtual COM Port and Data Gateway Interface
(DGI).
In conjunction with Atmel Studio, the EDBG debugger interface can program and debug the ATSAM4SD32C.
On the SAM4S Xplained Pro, the SWD interface is connected between the EDBG and the ATSAM4SD32C.
The Virtual COM Port is connected to a UART port on the ATSAM4SD32C (see section
implementation” on page 16
application through a simple terminal software. It offers variable baud rate, parity and stop bit settings. Note
that the settings on the target device UART must match the settings given in the terminal software.
The DGI consists of several physical data interfaces for communication with the host computer. Please,
see section
Communication over the interfaces are bidirectional. It can be used to send events and values from the
ATSAM4SD32C, 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. The DGI uses a proprietary protocol, and is thus only compatible with Atmel Studio.
The EDBG controls two LEDs on SAM4S Xplained Pro, a power LED and a status LED.

For further documentation on the EDBG, see the EDBG User Guide.
Hardware identification system
All Xplained Pro compatible extension boards have an Atmel ATSHA204 crypto authentication chip mounted.
This chip contains information that identifies the extension with its name and some extra data. When an
Xplained Pro extension board 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.
