you need to replace the atmel with hot air and obviously program the replacement.
This is it. But even if I manage to replace the atmel, I cannot seem to find the program to flash. This Chinese clone of transistortester is not mentioned in the docs. Am I missing something?
Hey, I am back. I scourged the new pages of this topic to see if anybody encountered this Chinese clone but was surprised that I am still the only one
I now have a new atmega328 (sadly, only in PDIP package as SMD is unavailable around here), however, my concern is that the HW of this clone is customized for the LCD and not compatible with the open source software. The LCD only has 12 contacts on flex cable and is marked "LX-12864TS Z". AFAIK, the other documented graphical LCDs have 14 contacts. This LCD is pretty much unknown to google, no docs, nothing.
The clone is made by fish8840 but all clones when I search for it, look totally different than mine.
So now I am not sure what to do (to reiterate: the original AVR is probably fried as cause of charged capacitor testing and now the tester measures wrong values). Maybe I could replace whole PCB and DIY a new one, reusing only the LCD and use PDIP atmega328.
Does this LCD sound familiar to anyone?
Also, I would like to try downloading existing firmware from the original AVR, to see if it is possible that the protection fuse bits would not be set. I was able to connect via ISP connector but unfortunately, the stupid auto-off functionality turns the chip off before I can do anything. Can I force it on somehow?
