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 ATMEGA256RFR2 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.

Pin on header ATmega256RFR2 pin 6 4.2 Peripherals 4.2.1 Crystals Function Shared functionality GND The ATMEGA256RFR2 Xplained Pro kit contains two crystals that can be used as clock sources for the ATmega256RFR2 device. Each crystal has a cut-strap next to it that can be used to measure the oscillator allowance. This is done by cutting the strap and adding a resistor across the strap. More information about 1 oscillator allowance and safety factor can be found in appnote AVR4100 Table 4-8.

The CE mark shall consist of the initials "CE" taking the following form: ● The CE marking must have a height of at least 5mm except where this is not possible on account of the nature of the apparatus. ● The CE marking must be affixed visibly, legibly, and indelibly.
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 6 digits of the serial number, which is listed under kit details, contain the product identifier and revision.
