I am totally new to programming AVR's. I just got the butterfly kit and book and have succesfully completed the first couple of steps in the tutorial. I just completed page 67 of the book, putting a bank of 8 switches on PortB and 8 LED's on PortD. I wrote the PortIO code, succesfully downloaded it and it all works OK. Next step is using the same hardware so I changed nothing. I wrote the code from page 70, compiled it, but now when I try to download it, all I get is a "No supported board found" error. I have been over it and over it and can't seem to figure what is wrong. The PortIO code is still on it and working. I do the usual, turn it off, turn it on, press and hold the button and select "AVRProg". Same error each time. I have checked battery voltage, they are brand new and are a touch over 3V.
Any advice would be appreciated.
