Re: AVR HV Rescue Shield Support

I'm very impressed by the investigation you've done into this issue. Glad that I'm the 'lucky' one to uncover the weird behavior. :- ) Thanks for the temporary, "hacky" fix, I'll give it a shot tonight and post my results. Don't worry about spending time over the holiday, we've all got holiday plans...

Re: AVR HV Rescue Shield Support

Jeff, thanks for the update. I only have one dip tiny13, the others are soic on my pcbs, and have too much other stuff on the circuit to work with HVSP. Yes, I did have debug mode enabled, while trying to figure out what was going wrong. I think I have a tiny24 or 44 lying around that I'll try later...

Re: AVR HV Rescue Shield Support

Also, I had trouble compiling when I changed to non-interactive mode by setting #define INTERACTIVE 0 . I think the issue is related to the curly brace on line 336 interacting (overlapping?) with the #if (INTERACTIVE == 1) block. Currently: else { // ATtiny2313: if I don't strobe OE here, the first ...

Re: AVR HV Rescue Shield Support

Hi Jeff, Just received my HV rescue shield 2.0 in the mail today, and soldered it up. I haven't bricked any AVRs yet, so I thought I'd try setting the fuses on an attiny13 I had lying around. I used interactive mode, and here is a short snippet of my serial session: Select mode: 1: ATmega (28-pin) 2...

Re: Looking for feedback...

Hey Jeff, I'm working on a handful of projects based on the tiny13a, which has only 6 IO pins, so I really need to use them all, including the reset pin. I've read that if I change the config fuses to use the reset pin as an IO pin, then I'll be unable to use my usbtinyISP programmer to reprogram th...
