Hi all,
I am kinda new to this and it looks like I locked up a tiny 12, set the reset disable fuse.
I have read the articles about resurrecting oscillator problems but they don’t apply. I also saw the post from wileur, but I need serial high voltage programming …

Anyone have a schematic for a high voltage serial programmer I can use with AVRDUDE or AVR Studio4 ?
I don’t want to buy a programmer (OK, I’m poor).

I also don’t see how to setup AVRDUDE to use the High Voltage programming procedure verses ISP procedures.

Any help?

Thanks
