#175582 - EEPROM need not be too slow. Responding to: ???'s previous message |
Eeprom writes are appallingly slow. Writing 1k will take between 5 and 10 seconds.
Most systems only have a few 'configuration' variables, so it is unlikely that you need 1k worth of EEPROM. When you do write to EEPROM, you read the contents first. And only write an altered value. This will make a very noticeable speed up. Eeprom has a limited endurance, so it is best to update your eeprom relatively infrequently. And critical values before a power loss. David. |

| i can,t understand what is the problem | 01/01/70 00:00 | |
| Either write less data to EEPROM or switch to 8-bit F-RAM | 01/01/70 00:00 | |
