I have purchased a batch of Attiny85s from Aliexpress. I normally use USBTiny device to program my Attiny85s. But these chips from Aliexpress could not be programmed in the usual way.
I built a circuit on a perfboard for high voltage programming using an Arduino Uno. My problem is that I can reset the fuses of my other Attiny85s but not of my new chips from Aliexpress. Can I say that the new chips are faulty or is there another way to recover them?
Thank you very much for your suggestions...
Why does HV programming of an Attiny85 not work?
