B4R Question keeping information on eeprom

[yaniv hanya]

Hello,

i use eeprom to save the username and password of wifi, using erel example.

now i need to keep wnother info (the keyboard situation- on or off. for cases of power off).
i need to "add" it to the previous info on the eeprom, without earesing it...

i can't understand how it wroks. can i keep it in another "HEADER" (in Erel example there is a header for SSID and password).

or should i read the previous info and then add it?

does any writing to eeprom erase all the info?

Not at all.

You can write it as a single byte, wherever you like. Just make sure that it is not at the beginning where the other values are stored.

The purpose of the MAGIC_EEPROM is to find out whether the data was already written once. You probably don't need it.
