i want to use a external crystal for my next project can anyone tell me how do i connect the crystal most probably to an atmega16 or32(circuit description) and also if any kind of programming needs to be done to initialize the crystal
using external crystal
How about reading the datasheet ?
Read the datasheet Unit "System Clock and clock options"
There are some fuse bits you have to set when you program the device.
Read carefully.

plzz can u explain me how to use fuse bits and how to change them i have got no idea abt them
which is the programmer that you use for programming AVRs?
iam using bsd parallel port programmer to program the device nad i dont have any idea how to change the fuse bits neither to disable jtag nor to use external oscillator
plzz help the data sheet seems kinda confusing
plzz can u explain me how to use fuse bits and how to change them i have got no idea abt them
Please, can you explain what part of the datasheet you did read in the last hour?
well the flash programming and memory programming those are the parts i read abt fuse bits
ok i know how to do it but wat are the commands for reading low and high fuse bits and writing these bits???
Try reading the documentation for your programmer!!
The process is different for each programmer.
And, watch out! Atmel uses a strange notation for "programmed" and some of the programmers have a history of users with problems. The worst is that you can accidently turn off the internal oscillator and have no way to program it again.

ok ill look about that
