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.

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. :)
