Hi oceanx,

if I understand what it is that you want maybe I can help you. If you want to give your data an offset en you have a base address, you should do it like this:

data = BASE_ADDRESS_OF_RAM_USED | 0x(hex-value);

this way your offset should be added with the base adress, which can be found in system.h. And data should be declared as a pointer....

Cheers,

Danny
