README.md

Code in this repository is for reading (more or less documented) ID bytes from the special section of the AVR chip memory. Based on the the 'speters' code and improved to read the whole part of the memory, including the Wafer ID and chip location on the wafer. Seems to be useful for identification of fake ATmega328 chips, where those bytes are usually intact (i.e. unprogrammed, 0xFF).

If you are interested on results of small experiment, here it is: https://senzor.robotika.sk/sensorwiki/index.php/FakeAVRchips

This is the result for the original and genuine Arduino Nano by Arduino S.r.l. (Italy) ``` 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 0x0000: 1E A9 95 FF 0F BA 00 26 FF 06 FF 17 FF FF 57 30
0x0010: 31 30 30 36 FF 0C 19 27 17 05 12 09 13 09 FF FF

Signature: 1E 95 0F (ATmega328P) Lot: 0W0160 Wafer: 12 X: 39 Y: 25 (Decimal) Fuses: Low: 0xFF High: 0xDA Ext: 0xFD Lock: 0xCF ```

Output for the counterfeit chip is similar to this one (note 0xFF on the Wafer ID an X, Y location bytes): ``` 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 0x0000: 1E AD 95 FF 0F FF FF 26 FF FF FF FF FF FF 58 FF
