Thanks for the offers of help and I have my first question...

2006-02-03 by lcdpublishing

Last night I was going over the documentation for the ATSTK500 board.  
As this thing seems to be the swiss army knife of programmers, it also 
comes with a lot of jumpers and cables.

I see that you can use either the clock signals from the board, OR you 
can put your own crystal on the board.  However, when I read through 
those directions, I could not make heads or tails of where to place 
the two related jumpers.

The jumpers I am referring to are XTAL1 and OSCSEL

Thanks

Chris

It depends on what you want to do, but using your own xtal directly is 
problematic due to the long transmission lines on that board. What I would 
suggest is using the board's clock circuitry. Here's how I have it set up:

xtal jump on. 
OSC jumper on the left two pins (if you can read the silkscreen)

There's a cheatsheet silkscreened on the bottom of the board for reference..

Thanks Micah,

Actually, I had it in my head backwards then.  When I read about the 
Xtal being problimatic dur to distance, I thought they meant the 
internal one which is what led me to think I should install the one 
I planned on using.

OKay, I will use the "standard" configuration to get going then.

Thanks

Chris
