Atmel ATmega256RFR2 Xplained Pro USER GUIDE 6, Atmel 42079E ATmega256RFR2 Xplained Pro User Guide 12 2015. 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 Embedded Debugger, The ATMEGA256RFR2 Xplained Pro contains the Atmel Embedded Debugger EDBG for on board. debugging The EDBG is a composite USB device of three interfaces a debugger Virtual COM Port and. a Data Gateway Interface DGI, Together with Atmel Studio the EDBG debugger interface can program and debug the ATmega256RFR2. On ATMEGA256RFR2 Xplained Pro the JTAG interface is connected between the EDBG and the. ATmega256RFR2, The Virtual COM Port is connected to a UART on the ATmega256RFR2 and provides an easy way to.
communicate with the target application through terminal software It offers variable baud rate parity and. stop bit settings Note that the settings on the ATmega256RFR2 must match the settings given in the. terminal software, Info If not set automatically data terminal ready DTR must be set in the terminal software. The DGI consists of several physical interfaces for communication with the host computer. Communication over the interfaces is bidirectional It can be used to send events and values from the. ATmega256RFR2 or as a generic printf style data channel Traffic over the interfaces can be. timestamped on the EDBG for more accurate tracing of events Note that timestamping imposes an. overhead that reduces maximal throughput Atmel Data Visualizer is used to send and receive data. through DGI, The EDBG controls two LEDs on ATMEGA256RFR2 Xplained Pro a power LED and a status LED The. table below shows how the LEDs are controlled in different operation modes. Table 3 1 EDBG LED Control,Operation mode Power LED Status LED. Normal operation Power LED is lit when power is Activity indicator LED flashes. applied to the board when any communication,happens to the EDBG. Bootloader mode idle The power LED and the status LED blinks simultaneously. Bootloader mode firmware The power LED and the status LED blinks in an alternating pattern. For further documentation on the EDBG see the EDBG User Guide. Atmel ATmega256RFR2 Xplained Pro USER GUIDE 7, Atmel 42079E ATmega256RFR2 Xplained Pro User Guide 12 2015.
3 2 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,Table 3 2 Xplained Pro ID Chip Content.
