Hi Andy,

I would never use I2C EEPROM like RAM.
Since its very slow on reading, extremely slow on writing. Also the write cycle are limited and page write should be preferred instead byte write.

Thus I use always a shadow memory to deal with data from the EEPROM. And only two functions (block read and write) are used to update the RAM or the EEPROM. Furthermore the block write routine checks first, if data are changed really to be most economical with the write cycle limitation.
