guys,
i am looking forward to read vibration data from triaxial accelerometer adxl335...which i bought from sparkfun. now i want to view these vibration signals sensed by the accelerometer on my pc.
so wat should i do?
can any body guide me through what i should do?

Unless you need a multi-node mesh network (not a star network) you don't want the high complexity of ZigBee.
IEEE 802.15.4 is the underlying protocol and that's what's prudent.

Contiki has a data collection example; the following is for a MSP430, IIRC, but the core of it is in C and XML:
http://www.sics.se/contiki/wiki/index.php/Simple_Contiki_Data_Collection_on_the_Tmote_Sky
The Contiki platform/board support for wireless AVR is: mega128RFA1 MCU, Raven boards, RCB board, ZigBit modules, STK500.
Edit: RCB correction.

Bluetooth (i.o.w. wireless USB) is another way (likely serial port profile (SPP)).
Atmel does not have much in this area except a Bluetooth accessory board for AVR32, software in Atmel's ASF, and USB sensor examples:
http://www.atmel.com/tools/SENSORXPLAINEDDEMONSTRATIONPROJECTS.aspx
Atmel Data Visualizer at that URL would run on the Windows PC.
Bluetooth has the advantage that it's built-in for a lot of laptops, netbooks, PDAs, and mobile phones and is easy to add to a PC.

Ajax push works on most web browsers, not IE however. The nodes can deliver tcp messages at timed intervals for processing in javascript. You can dump the data into comma separated values in a scrolling text box for copy/paste into a spreadsheet, or use a plotting library for realtime browser display (such libraries can be loaded from public web sites, no need to send a 400K .js file through 802.15.4 :) ). The big advantage is independence from operating system. Contiki has an example for an accelerometer on a ZigBee board, no fancy graphing though.

i want to connect my adxl335 breakout board to some device which is cheap and can send my signals in range of 2-5m to a cheap receiver connected to pc via usb.
and ii want to see all my vibration signals on pc.
so what should be my transmitter to which i should connect my breakout board and which software application should i look forward to.

i want to interface cc2500 with adxl335(breakout board from sparkfun). so can anyone provide me the schematic of the interfacing between cc2500 and my adxl335.
i will be very grateful to you.

As adxl335 has three signals coming out each for x y and z axis respectively.
so should i use an avr and an encoder before connecting to cc2500?

if yes then pls give me its schematic so that i am confirm ...

well will it be more convenient to use tx433 and rx433 instead of zigbee?
