4. Xplained Pro
Xplained Pro is an evaluation platform which contains a series of microcontroller boards (evaluation kits)
and extension boards. Atmel Studio is used to program and debug the microcontrollers on these boards.
Atmel Studio includes ASF and Atmel START, which has drivers and demo code, and Data Visualizer,
which supports data streaming and advanced debugging. Xplained Pro evaluation kits can be connected
to a wide range of Xplained Pro extension boards through standardized headers and connectors.
Xplained Pro extension boards have identification (ID) chips to uniquely identify which boards are
connected to the Xplained Pro evaluation kits.
4.1 Embedded Debugger
The SAM E54 Xplained Pro contains an Embedded Debugger (EDBG) for on-board debugging. The
EDBG is a USB composite device with the following interfaces:
• Debugger
• Virtual COM Port
• Data Gateway Interface (DGI)
The EDBG can program and debug the ATSAME54P20A with the help of Atmel Studio. The SWD
interface is connected between the EDBG and the ATSAME54P20A on the SAM E54 Xplained Pro.
The Virtual COM Port is connected to a UART on the ATSAME54P20A and provides an easy way to
communicate with the target application through terminal software. It offers variable baud rate, parity, and
stop bit settings. The settings on the ATSAME54P20A 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 ATSAME54P20A. If the
DTR signal is not enabled, the UART pins on the EDBG are kept in tri-state (high-z) to render
the COM Port not usable. The DTR signal is automatically set by some terminal software, but it
may have to be manually enabled in your terminal.
The DGI consists of several physical interfaces for bidirectional communication with the host computer.
Communication over the interfaces is bidirectional. It can be used to send event values, and data from
the ATSAME54P20A. Traffic over the interfaces can be timestamped by the EDBG for more accurate
tracing of events, but timestamping reduces the maximal data throughput. The Data Visualizer is used to
send and receive data through DGI.
The EDBG controls two LEDs on the SAM E54 Xplained Pro: a power LED and a status LED. The table
below shows how the LEDs are controlled in different operation modes.
