preprocessor command as CBLOCK in assembler

[Fabri]

Hi everybody,

I need to define a block string as constant.
In assembler I used CBLOCK to define a block of location as follow:

Nothing quite the same in terms of a 'named' list. Remember though, that #ROM, will allow you to place data of any type at a location, so a structure with named elements can be placed where you want. However in general, in C, you wouldn't bother. Why would you need to put something at a spcific location?. In general, much easier just to declare a const structure or array, and let the compiler put it where it wants.
#Defines,won't do this at all (they are only preprocessor commands, and do not actually store anything).

Hi Ttelmah,

I have to define some eeprom location where read and write specific data.

In my project there is over 200 eeprom location.

Actually i use #define, have you got any idea ?

Thanks,

I suppose you mean that you 'define' a symbolic 'name' for the location, to give it 'significance', and then access this with the read_eeprom function?.
This would be 'distinct' from what can be done using a structure defined 'at' a memory location (which would include the retrieval code).

You can do this with the C 'enum'.
So:

enum EEPROM_LOCN {one=100,two,three,four,five };

etc..

Best Wishes
