• EVK1100
• Evaluation kit and development system for the
  AVR32UC3A family
• EVK1100 is a fully functional embedded computer
  system.
• Circuit board has a flexible power system that
  accepts 8-20V DC input and can be operable via
  USB port.
• The EVK1100 embeds an Atmel Data flash (8MBytes)
  and a SDRAM (32MBytes).
• Several communication interfaces are available on
  the EVK1100 RS232, USB and ETHERNET.

• Building a Project
• Select the project from the project plan (on left
  side of the window) and right click
• Click Build Project

Workspace creation Project creation Project
building Target Creation Loading program

• Build complete for project myproject
• Debug directory will be added in the workspace
• myproject.elf will be created in the Debug
  directory and is ready to be loaded in the
  controller

• For Programming EVK1100 there are three listed
  methods available, (Note we can use two among
  them)
• In system Programming (ISP)
• Programming Via JTAG port
• Self Programming via One chip BOOT program
• Tool for using programming is JTAG or USB cable
  (for ISP)
• JTAG ICE mkII

• For Programming EVK1100 we need to add a Target
• Scan the target as shown in Picture

• Configure the target device i.e JTAGICE mkII for
  downloading your program

21

• Loading Code in the Micro-controller
• Loading through USB DFU
• Loading through JTAG

building Target Creation Loading program
On EVK1100 Press the joystick downwards and hold
it. Now press the re-start button to put the
device in programming mode

• On AVR Studio
• Right-click on target for USB-programming and
  click program.
• Browse the target file and press ok in newly
  appeared window to start loading the program

22

• Loading Code in the Micro-controller
• Loading through JTAG

Application

• Our WSN Platform (Sentio)
• Number of different platforms targeting different
  application areas
• SENTIO a stackable platform developed in 2004
  (IEEE802.15.4 compatible(Zigbee), having three
  layers i.e communication layer, processing layer
  (Atmel Mega 128L 8-bit uC), and analog/digital
  interfaces to sensor layer. Sufficient for short
  range communication.
• SENTIO-HP high-precision wireless instrument that
  can be used for characterizing processes
• SENTIO-BT for urban sensing applications.
• SENTIO-e2 for  environmental monitoring,
  communicating at 433MHz at ranges up to 1 km.
  Global communication via GSM/GPRS or to a PC via
  USB

• SENTIO32
• A latest platform that is very compact with
  (IEEE802.15.4 compatible (Zigbee)) and processor
  (AVR32) on the same board.
• It is a Development Board, can be used for
  variety of wireless sensor applications
