this will also allow you to read exactly what is being transmitted in real time and the software will even decode the SPI and I2C protocols on the fly.
Thanks for the tip.
Why didn't i think of that ? It make so much sense.
Earlier this year, i've been probing a Burg Wachter Secutronic with a logic analyzer. I hooked it up between the keypad and the lock.
But i kind of put it aside after i couldn't get the Manchester encoding to work with zero to little effort. Haven't went back to it since.
I never tought of reading the on board EEPROM.
So, armed with this knowledge i spend this afternoon reading EEPROMS from secutronic safes. I have a few, different generations, lying around.
Long story short: i can now recover the code if i can access the EEPROM (it's on the inside of the safe).
*edit: after looking around for a short while, i found a Manchester decoder for my software. Looks like many sleepless nights ahead.
