Does anyone have developed the code to check the CRC of an ibutton connected via one-wire to a quadi-directional port ?
I'm studing how to develop it, there's someone who want speak about ?
Note that there are (at least) two different CRCs used with iButtons and other 1-Wire (TM) devices:
There's the 8-bit CRC in the Serial Number;
Some devices also use a 16-bit CRC with their data "payload"...
See the sepcific device Datasheet for details.
