AVR309 USB - RS232 application note

2005-04-11 by Geo

Hi,

Apologies if this has already been mentioned but a search of the yahoo list 
did not find avr309.
Looks to me like a work of art - 1 small common avr, 1 crystal (ok 
overclocked) and a 1.5k resistor - virtually all that is required for a USB 
interface.

Do not bother with the original authors web site - it no work.
But there is a mirror at:-

pdf from:-
http://www.mikrocontroller.net/attachment.php/86320/AVR309_doc2556.pdf

all files from (watch any word wrap):-
<http://www.avrfreaks.net/index.php?module=FreaksFiles&func=viewFile&id=9
63&showinfo=1>

a modular (c and asm) implementation here with two example applications 
including circuit diagrams and source:-

Well I am impressed anyway...

luck,

George Smith
