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 OLED1 Xplained Pro to an Xplained Pro MCU board and connect a USB cable to the
DEBUG USB port on the Xplained Pro MCU board.
When the Xplained Pro MCU kit is connected to your computer for the first time, the operating system will
perform a driver software installation. 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.
Once the Xplained Pro MCU board is powered the green power LED will be lit and Atmel Studio will auto
detect which Xplained Pro MCU- and extension board(s) are connected. Atmel Studio will present
relevant information like datasheets and kit documentation. The kit landing page in Atmel Studio also has
the option to launch Atmel Software Framework (ASF) example applications for the kit. The target device
is programmed and debugged by the on-board Embedded Debugger and therefore no external
programmer or debugger tool is needed.
2.2. Design Documentation and Relevant Links
The following list contains links to the most relevant documents and software for OLED1 Xplained Pro:
•Xplained products - Atmel Xplained evaluation kits are a series of easy-to-use evaluation kits for
Atmel microcontrollers and other Atmel products. For low pin-count devices the Xplained Nano
series provides a minimalistic solution with access to all I/O pins of the target microcontroller.
Xplained Mini kits are for medium pin-count devices and adds Arduino Uno compatible header
footprint and a prototyping area. Xplained Pro kits are for medium to high pin-count devices, they
features advanced debugging and standardized extensions for peripheral functions. All these kits
have on board programmers/debuggers which creates a set of low-cost boards for evaluation and
demonstration of features and capabilities of different Atmel products.
•Atmel Studio - Free Atmel IDE for development of C/C++ and assembler code for Atmel
microcontrollers.
•Atmel Data Visualizer - Atmel Data Visualizer is a program used for processing and visualizing
data. Data Visualizer can receive data from various sources such as the Embedded Debugger Data
Gateway Interface found on Xplained Pro boards and COM ports.
•Hardware Users Guide in PDF format - PDF version of this User Guide.
•Design Documentation - Package containing CAD source, schematics, BOM, assembly drawings,
3D plots, layer plots, etc.

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. 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.

Minimum Voltage [mV] uint16_t 3000
Maximum Voltage [mV] uint16_t 3600
Maximum Current [mA] uint16_t 30
3.2. Xplained Pro Headers and Connectors
3.2.1. 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.
The extension headers can be used to connect a variety of Xplained Pro extensions to Xplained Pro MCU
boards or to access the pins of the target MCU on Xplained Pro MCU boards directly.

4.1. Electrical Characteristics
OLED1 Xplained Pro can be connected to several Xplained Pro MCU boards and manually connected to
other hardware. Xplained Pro MCU board(s) that does not have 3.3V as its primary target voltage will
read all ID devices on connected extensions to check if they support the target voltage before enabling it
to the extension headers. The table below shows the static content written in the ID chip.

4.2.1. OLED1 Xplained Pro Extension Header
OLED1 Xplained Pro implements one Xplained Pro standard extension header marked with EXT in
silkscreen. This header makes it possible to connect the board to any Xplained Pro MCU board. The pin-
out definition for the extension header can be seen in the table below.

4.3. Peripherals
4.3.1. LEDs
There are three yellow LEDs available on OLED1 Xplained Pro. The LEDs can be activated by driving the
connected I/O line low.

4.3.2. Push Buttons
There are three push buttons available on OLED1 Xplained Pro. When a button is pushed the
corresponding I/O pin is connected to ground. There are no external pull-up resistors on OLED1 Xplained
Pro, so internal pull-up resistors have to be enabled in the target microcontroller.
Info: Remember to enable internal pull-up resistors in the target device to get a defined
electrical level on the I/O lines connected to the buttons.

4.3.3. OLED Display
OLED1 Xplained Pro features a 128 x 32 pixel white monochrome OLED display, UG-2832HSWEG04
from WiseChip Semiconductor Inc. The display has a SSD1306 display controller by Solomon Systech
built in and is controlled via a 4-wire SPI interface + reset with the signals described in the table below.
The datasheets for the display module or the display controller is not publicly available and has to be
acquired from the respective manufacturers.
Info:
Note that the OLED display does not have a SPI MISO signal. That means that data can only
be written to the display, not read.

Signal Name Description
16 SPI_MOSI SPI master out, slave in signal. Used to write data to the
display.
18 SPI_SCK SPI clock signal, generated by the master.
5 DATA_CMD_SEL Data/command select. Used to choose whether the
communication is data to the display memory or a command to
the LCD controller.
15 DISPLAY_SS SPI slave select signal, must be held low during SPI
communication.
10 DISPLAY_RESET Reset signal to the OLED display, active low. Used during
initialization of the display.

5. Hardware Revision History and Known Issues
5.1. Identifying Product ID and Revision
The revision and product identifier of Xplained Pro boards can be found in two ways; either through Atmel
Studio or by looking at the sticker on the bottom side of the PCB.
By connecting an Xplained Pro MCU board to a computer with Atmel Studio running, an information
window will pop up. The first six digits of the serial number, which is listed under kit details, contain the
product identifier and revision. Information about connected Xplained Pro extension boards will also
appear in the Atmel Kit's window.
The same information can be found on the sticker on the bottom side of the PCB. Most kits will print the
identifier and revision in plain text as A09-nnnn\rr, where nnnn is the identifier and rr is the revision.
Boards with limited space have a sticker with only a QR-code, which contains a serial number string.
The serial number string has the following format:
"nnnnrrssssssssss"
n = product identifier
r = revision
s = serial number
The product identifier for OLED1 Xplained Pro is A09-1769.
5.2. Revision 3
Revision 3 of OLED1 Xplained Pro is the initial released version.
OLED1 Xplained Pro boards with a serial number that ends with a number lower than 11148 may have a
wrong revision programmed into the Xplained Pro ID chip. This will only affect the information displayed
by the Atmel Kits extension in Atmel Studio. It will not affect the operation of the board.
