I apologize for the maybe stupid question. For the first time planning to use EEPROM for a larger number of calibration constants, saving operating modes (such as the number of starts) and logging errors. Seeking examples or libraries for this purpose. Pperhaps a graphical utility for assigning addresses and generating an address in EEPROM
then normal C optimization would add a pad byte
Optimizition may not have much to do with it. It may just as well be a necessity.
Well, it is a form of optimization to not have to treat the data as packed and split an access into multiple loads or stores :)
