#92052 - Here is an idea... Responding to: ???'s previous message |
Put your few bytes of data into a data structure definition. Then add some kind of check code to it like a CRC or XOR-LRC code. Allocate a couple blocks of the card....say zero and one and write the copies of the data there...
For such a small amount of data I would really look into using a very low cost serial EEPROM such as a 93C46 or a Dallas I-Button 1-wire RAM/EEPROM product. Michael Karas |

| Thought about an EEPROM but... | 01/01/70 00:00 | |
| if only add data and read it all at once | 01/01/70 00:00 | |
| How big? | 01/01/70 00:00 | |
| FAT might be overkill... | 01/01/70 00:00 | |
| Another reason not to use FAT. | 01/01/70 00:00 | |
| I agree | 01/01/70 00:00 | |
| I found this too. | 01/01/70 00:00 | |
| Good! | 01/01/70 00:00 | |
| Are you sure? | 01/01/70 00:00 | |
| Hmmm | 01/01/70 00:00 | |

| I got three | 01/01/70 00:00 | |
| if what you are saying is | 01/01/70 00:00 | |
| Hard work? | 01/01/70 00:00 | |
I agree | 01/01/70 00:00 | |
| If you decide on FAT support.... | 01/01/70 00:00 | |
