USER GUIDE Atmel SAM4S Xplained Pro Preface The Atmel® SAM4S Xplained Pro evaluation kit is a hardware platform to evaluate the ATSAM4SD32C microcontroller. Supported by the Atmel Studio integrated development platform, the kit provides easy access to the features of the Atmel ATSAM4SD32C and explains how to integrate the device in a custom design. The Xplained Pro MCU series evaluation kits include an on-board Embedded Debugger, and no external tools are necessary to program or debug the ATSAM4SD32C.

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 an USB cable to the DEBUG USB port. Connecting the kit When connecting Atmel SAM4S 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 Maximum Voltage [mV] uint16_t 3600 Maximum Current [mA] uint16_t 30 Power supply The SAM4S 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 “Power header” on page 10. The available power sources and specifications are listed in Table 3.3, “Power sources for SAM4S Xplained Pro”. Table 3.3.

The kit will automatically detect and switch to the external power if supplied.
4. Hardware user guide 4.1 Connectors This chapter describes the implementation of the relevant connectors and headers on SAM4S Xplained Pro and their connection to the ATSAM4SD32C. 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 SAM4S Xplained Pro headers EXT1, EXT2 and EXT3 offers access to the I/O of the microcontroller in order to expand the board e.g.

One button is the RESET button connected to the SAM4S reset line and the other is a generic user configurable button. When a button is pressed it will drive the I/O line to GND. Table 4.11. Mechanical buttons 4.2.
4.3.3 Pin on SAM4S Function PB2 UART RXD (SAM4S RX line) Atmel Data Gateway Interface The Embedded Debugger features an Atmel Data Gateway Interface (DGI) by using either a SPI or TWI port. The DGI can be used to send a variety of data from the SAM4S to the host PC. For further information on how to use the DGI interface see “Embedded Debugger” on page 6. Table 4.15.
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, 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 6 digits of the serial number, which is listed under kit details, contain the product identifier and revision.
