[...] need to flash another firmware, you will need to reset the fuses using a High Voltage programmer; this one worked fine for me. AVR GNU toolchain is used for this project, so the code is written in GNU [...]

ATtiny84 wiring require more pins to be connected to GND:

hey , would this work on other atmel chips like atmega specially atmega8 ?
thanks

Hi,

Has anyone tried this on a bricked ATTiny2313?
Does the serial high-voltage programming mode program the SPIEN bits on the 2313?

Thanks

Thanks, this saved my butt

Glad to hear it worked for you Thierry. It looks like the absolute maximum rating for the reset pin is 13 volts if someone has an odd value transformer.

Hi,

I wanted to thank you for this excellent work and programmer, which I used successfully to revitalize two “broken” attiny45. For the 12 V source, I used directly (without regulation) a wall plug adapter which provided ~ 12.5 V. I also used a BC337 as a switch transistor instead of the 2N3904. Thanks again for sharing your work like this !

Glad to hear you got things working studio. I am indicating the equivalency between the Arduino pins on the schematic and the Teensy++ 2.0.

To be a little more clear:
Attiny85 pin 2 connects to Arduino pin 12 or in your case Teensy++ 2.0 pin C2.
Attiny85 pin 7 connects to Arduino pin 11 or in your case Teensy++ 2.0 pin C1.
etc.

Is this the way you wired it up? If not maybe a picture of the correct setup could help clear things up.

I am getting these pin mappings from this picture, http://www.pjrc.com/teensy/teensyduino.html and a table http://www.pjrc.com/teensy/td_digital.html

Thank you for your reply.

In the meantime while I was waiting for my post to be moderated I jumped in the deep end and wired it up. It all worked perfectly. If it helps anyone else, I used a 2N2222A transistor and a 12v power pack from a cheap USB->SATA/IDE converter and connected it following the pin numbers in the schematic. I have saved my first tiny85 :D happy days.

I must admit I didn’t quite follow your post, are you indicating the connection pins between the Arduino and Teensy++ 2.0 or the equivalents between them? In my case I simply connected using the same Arduino pin numbers as the schematic and it worked perfectly.
