Hello, I found your project by searching for a solution to reanimate an ATtiny85. I also do have some of the smallest ATtiny (4,5,9,10). Will there be an Update for these Versions of the ATtiny family?...

There wont be any support for TPI protocol. If you disable RESET pin then only difference in TPI programming is that you need to put +12V on your reset line instead of GND. You can add some NPN+PNP...

And your fw version is? 2.10 is bugged so it doesnt write high byte, use 2.11 if thats the problem.

Hi man. Thank you very much for the efforts on this project. I got ahold of a bunch of AT90S1200 chips with enabled locked bits, hope I will be able to put the fusebit doctor together :)

Jak się podłącza do układu doktora procek attiny13? Jego nota nie wymienia wysokonapięciowego programowania równoległego, jedynie szeregowe (chyba za mało nóżek :D ), pokazujesz go jako obsługiwany...

W załączniku masz projekt adaptera HVSP który należy wykonać aby móc odblokowywać procki HVSP.

Hi there! Thank you again so much! I’ve spent this entire day making the Fuse Doctor, and I succeeded (I think). After assembly I had only one bug on PCB (broken line), which I found and fixed pretty...

Lockbits in AT90S (and all AVR chips) can be erased by „chip erase” command via ISP programmer. HVPP is only needed when SPIEN was disabled. But it will also do the job. I disabled donations a lot of...

Thank you man, you’re the best! I’ve got a bunch of PCBs with AT901200-12PI chips on them, basically I’ve got them from trash. They have both lockbits set, SPIEN off and RCEN on. I’ve tried using...

Ok, im confused. Can you paste here repair log from terminal? And add some comments what should be and what actually is and why. What do you mean by it breaks first byte of ship signature? „1E” is...

I know, sounds strange, I probably messed up PCB or something. Now testing with tiny2313a. ISP programmer reads chip ID fine, fuses are E4:DF:FE, LOCK is FF, flash is programmed with small program. I...

Your comment was flagged as „waiting for moderation”, so it was waiting for my decision before it became public. Ok, so T2313 is working fine. And now AT90?

If I sent prev. comment twice, it was by mistake, sorry about that. Ok, trying AT90S1200 now. My ISP programmer says it has wrong signature (doesn’t display it though) and says fuses are 00:00. I think...

Upd: found this in documentation to AVRDude: «(****) The ISP programming protocol of the AT90S1200 differs in subtle ways from that of other AVRs. Thus, not all programmers support this device. Known...

Yes, i also had problems with this chip, i remember i was fixing this in 2 or 3 releases, but somebody tested it in real life and wrote that everything works ok. If fuse doctor reads signature...

That’s what I think happened – my ISP programmer definitely broke the chip signature. I’ve tried several versions of software, to no result. I’ll get my old PC that has LPT port and will try to program...
