Hello,

I have successfully programmed an arduino uno with these hex files. on a 16u2 based uno. I have gone out and purchased a couple 16u2 chips, and had wired them up based on the datasheet. I even tried to wire them up based on the Arduino schematic. I unfortunately unable to get them to accept programming. I was hoping maybe you've tried this and may have a schematic that works Thoughts?

Looks similar to what I tried I'll have to try again this weekend. Thanks.
