How can I define constants with indart / assembler in the EEPROM.

Thanks and regards

With Cosmic compiler:

You can use @eeprom to declare variables in EEPROM

@eeprom char var1;

or you can use #pragma to declare all your variables in EEPROM

The compiler uses a runtime library for eeprom variable operations

With Metrowerks compiler:

You can define a different data segment for EEPROM variables and constants and then define this segment in .prm file

in source file use

#pragma DATA_SEG EEPROM_DATA

unsigned char var1;

in .prm file use

PLACEMENTS

EEPROM_DATA INTO EEPROM

refer to compiler manual for read write operations as they may require some EEPROM register settings.

Hope this Helps,

Best Regards,

Dear PraveenG

Thanks for Your answer.

My concern are constants (like look- up tables or character- strings) directly programmed in the EEPROM with InDart / Assembler.

Kind regards
