Title: Can't upload to UNO
Post by: cmcclellan on Jan 05, 2013, 03:58 am
I can't upload my programs to my uno board.  I was attempting to connect it to my iRobot Roomba and I think it short circuited the uno.  Any suggestions?

Try a new AtMaega chip with bootloader

I think the problem is the RX pin for the AtMega 16u2.  If so, how would I try a new AtMega chip?

If it is that, you need a new PCB

Why do you think that?

I think we might be able to use some details as to how it was wired up. Right now there's not enough information to make a good guess yet.
