Testcode to read/write data on a DS1961 SHA-1 iButton

Commands to query the ibutton over the serial connection:

  • P

    Poll for found iButton id numbers

  • S XXXXXXXXXXXXXXXX

    Write the 16 hex-digit secret to the iButton

  • C XXXXXX

    Do an authenticated read with the 6 hex-digits as 3-byte challenge Prints the data (all zero currently) and the 160-bit MAC, which is computed from the data, ibutton id, ibutton secret and challenge code.
