Introduction to Development Board 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’

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

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

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

Application

Our WSN Platform (Sentio)o 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

23-04-21

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
