2. Getting Started 2.1 Quick-start 3 Steps to start exploring the Atmel Xplained Pro Platform 2.2 1 ● Download and install Atmel Studio ● Launch Atmel Studio ● Connect a Micro-B cable to the DEBUG USB port Connecting the Kit When connecting Atmel SAM4E Xplained Pro to your computer for the first time, the operating system will do a ® ® driver software installation. The driver file supports both 32-bit and 64-bit versions of Microsoft Windows XP and Windows 7.
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 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.
3.3 Data Field Data Type Example Content Minimum Voltage [mV] uint16_t 3000 Maximum Voltage [mV] uint16_t 3600 Maximum Current [mA] uint16_t 30 Power Supply The SAM4E Xplained Pro kit can be powered either by USB or by an external power source through the 4pin power header, marked PWR. This connector is described in “Xplained Pro Power Header” on page 10. The available power sources and specifications are listed in Table 3-3, “Power Sources for SAM4E Xplained Pro” on page 7. Table 3-3.
Pro Extension Header” on page 8. The extension headers can be used to connect a wide variety of Xplained Pro extensions to Xplained Pro MCU boards and to access the pins of the target MCU on Xplained Pro MCU board directly.

4. Hardware User Guide 4.1 Connectors This chapter describes the implementation of the relevant connectors and headers on SAM4E Xplained Pro and their connection to the ATSAM4E16E. The tables of connections in this chapter also describes which signals are shared between the headers and on-board functionality. 4.1.1 I/O Extension Headers The SAM4E Xplained Pro headers EXT1, EXT2 and EXT3 offers access to the I/O of the microcontroller in order to expand the board e.g.

The DGI can be used to send a variety of data from the SAM4E to the host PC. For further information on how to use the DGI interface see “Embedded Debugger” on page 6. Table 4-18.
5. Kit Specific Data One of the user pages in the EDBG is programmed with data specific to the SAM4E Xplained Pro. The data 2 can be read through the I C interface connected to the EDBG, for detailed information see the EDBG User Guide on page 5. All data is stored as little endian. Table 5-1.
6. Hardware Revision History and Known Issues 6.1 Identifying Product ID and Revision The revision and product identifier of Xplained Pro boards can be found in two ways, through Atmel Studio or by looking at the sticker on the bottom side of the PCB. By connecting a 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.
