Hardcode EEPROM size

[fg89o]

I think there should be a posibility to set EEPROM size in begin() method. Before your last merged I did a test with an EEPROM_offset and works correctly but changing the line

EEPROM.begin(512).

For example, If I need 400 bytes for my main project and I want another 512 bytes for INA library the begin method should set EEPROM to 912. Right?. You can expose antoher variable to set EEPROM size and initializate to a default value to have backwards compatibility.

In the other hand, you calculate max_devices including the EEPROM_offset variable ,If the library is not allowed to use the offset, the maximum devices should be:

maxDevices = (EEPROM_size - _EEPROM_offset ) / sizeof(inaEE);

instead of

maxDevices = (_EEPROM_offset + EEPROM_size) / sizeof(inaEE);

I did all the tests with an ESP32. Hope something of that help you to improve the library,

:thumbsup: I missed that, good catch and I've added the correct offset math to the code.

Are you going to create the EEPROM size variable too?.

I wanted to fix the actual bug first, before the new release was published.

I still need to think about changing the begin() method, which is why this issue is still open.

What I will do is add another public uint16_t variable "_EEPROM_size" which is only valid for the ESP32 and ESP8266 platform. It defaults to 512 but can be changed before the begin() is called.

Perfect! Thank you for your support.

OK, that should work!
