My TC1 comes with ATMega328p DIP IC. I am not an expert in but if I could get complied code, I would be able to fix it. Please help me :) :) --- End quote --- There are compiled versions out there. But on another note, while a pin or two might be fried, you may still be able to read the Flash and eeprom. (You need both) Then simply write it to a new chip. Depends on whether the chip has copy protect enabled or not. --- End quote --- Can you please provide the link of the compiled code for tc1 with dip Atmega328p?? And where to find the fuse bits?? I have tried to read but the mcu is read protected :-[ |

So I have to replace the atmega328p. But I need the compiled code and Fuse bits. I will be greatful if you please help me. :) --- End quote --- In case you're looking for an OSHW firmware: https://github.com/madires/Transistortester-Warehouse |
