Detailed Description

Data storage object for one entry.

Must be defined in the CO_driver_target.h file.

For more information on Data storage see Data storage base or CO_storage.h file. Structure members documented here are always required or required with Data storage in eeprom. Target system may add own additional, hardware specific variables.

Field Documentation

subIndexOD

uint8_t CO_storage_entry_t::subIndexOD

Sub index in OD objects 1010 and 1011, from 2 to 127.

Writing 0x65766173 to 1010,subIndexOD will store data to non-volatile memory. Writing 0x64616F6C to 1011,subIndexOD will restore default data, always required.
