| CRC8 instead of CR32 | 01/01/70 00:00 | |
| I am talking about CRC-16 not CRC-8 | 01/01/70 00:00 | |

| how much data? | 01/01/70 00:00 | |
| approx 40-60 bytes | 01/01/70 00:00 | |
| I use 2 copies and a counter for that | 01/01/70 00:00 | |

| Here's one method | 01/01/70 00:00 | |
| another interesting scheme! | 01/01/70 00:00 | |
| Try the Dallas 1-wire CRC | 01/01/70 00:00 | |
| another good idea but... | 01/01/70 00:00 | |
| I just meant the CRC | 01/01/70 00:00 | |
