Re: cannot rescue two 328P-PU chips

I spoke too soon -- those weren't the bad chips I'd been testing -- with 7 or 8 328's lying around it's easy to mix them up. I have recompiled the sketch for the Mega, but unfortunately it's still not able to read or write fuses to the two dead chips. Both respond: Insert target AVR and press button...

Re: cannot rescue two 328P-PU chips

I thought I had -- but I must have only tested both values (0, 1) when using a standard Arduino Uno. I did upload the sketch with the correct setting, and now I'm able to read the fuses. Both chips read FF and DE for low and high. I set the values to 62 and D9 to see if they would successfully write...

Re: cannot rescue two 328P-PU chips

Thanks for the reply ... When I attempt to set the values (using the sample values or the values found on a forum for a 328), the sketch indicates the values have been written, but the sketch still replies with 3 as the existing fuse values. I also tried to set them to FF. If the sketch is only able...

cannot rescue two 328P-PU chips

I am trying to use this board to revive two apparently dead 328p-pu chips. Neither can be placed into programming mode by a standard ISP board, both read 3 for the built in fuse values by the HV Rescue Shield, and neither will accept a sketch (on two different Uno boards). There are slight differenc...

Re: Looking for feedback...

Initial setup very clear, straightforward. I tested it by pressing the 28-pin socket into place, then soldered a ZIF socket into place. Nothing to comment on the instructions. Despite my Vulcan-sounding criticism, you have a great product. Keep up the good work! I purchased it to revive two apparent...
