Instead of expecting us to give you all the steps; try it out, fail a couple times and win a couple times. In theory it should react to some commands.

Select all 85 1 [cmd] [arg1] [arg2]. Data is transferred serially via the 1-Wire protocol, which requires only a single data lead and a ground return. DS datasheet and specification datasheet. D 1wire is really simple; the bus pirate does all the work all you have todo is send the correct commands and tell the bus pirate when to read the line Registers TA1 and TA2 must be loaded with the target address to which the data] This command allows the bus master to read the DS ‘s 8-bit family code, unique bit serial number.

The features of the DS and security of SHA-1 provide a low-cost method tosmall electronic pay systems, or create tamper-proof data carriers.

Engine to Compute Bit Message. All ROM function commands are eight bits long.

Applications of the DS include intellectual property security, after-market. The next 48 bits are a unique serial number. The DS has an additional ds2342 area called the scratchpad that acts as a buffer when writing to the main memory, the register page or when installing a new secret. The SHA-1 engine can also be activated to compute.
