You can use the multibyte read and set size to 1. The code for a single byte read would be just about identical and just makes the lib larger.

The code for single and multi byte write on the other hand has more differences. BTW a quick look at the code shows that multibyte write is probably not very efficiently implemented. The memory address is set again for each byte. This should be auto-incremented by the EEPROM.

Great. I will look forward to optimize multi byte write and make a pull request. Will take some time until my pcbs arrive. Do you recommend any other lib for 24LC64 as a "standard"?

The component page has some examples https://developer.mbed.org/components/cat/storage/

The multibyte write didn't work as it didn't recognized page size. (You can not write over the page border). We have cleaned up and added a correct multibyte write to the library here: http://developer.mbed.org/teams/Akafugu/code/_24LCXXX/

Pull requests are pending.

Thank you everyone.

I'm not familiar with how to use the mbed web. I published a half-hearted Archives that made the time being. It seems to have become as they left the state.

Like I have in the code that was written there was a bug. I am grateful. you for correction.
