<DIV><FONT face=Arial size=2>Well today was an educational and busy day with
the atmel website.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>It was also close but not quite a living hell
with WinDraft.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have posted a bmp with my current schematic
plans based on the AT90S2323 part. The only draw back to this part is
that it does not have a built in UART. So one will have to be written in
software, anyone with a good AVR background want to tackle that? I am
sure I can do it, but it might take me a while.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>If I can't come up with a software UART solution
I can change over to the 2313 part which has a built in UART. Of course
the part is also 20 pin instead of the tiny 8 pin 2323 with lots of left over
pins wasted.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I will be basing the software off of one of the
atmel application notes: AVR313. That note is for the 8515 part (a 40 pin
part) but I think I can adapt it well enough (once again assuming a software
UART can be written).</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Looking for feedback.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The bmp (and my schematic file and a start of an
atmel part library) are at: <A

<DIV><FONT face=Arial size=2>If anyone has more experienced with WinDraft and
wants to clean up the schematic I wouldn't mind a bit :) Or if you know
how to edit a part in a library after you have closed the dang library
file.</FONT></DIV>
